[gentoo-user] Do we have to build gcc with fortran now?

I just did my updates and ran into this:

policykit userland_GNU
  * FEATURES:   preserve-libs sandbox

  * If you intend to use a different compiler then gfortran, please
  * set FC variable accordingly and take care that the neccessary
  * fortran dialects are support.

  * ERROR: sci-libs/blas-reference-20070226 failed (setup phase):

This is my gcc info:

So, does everyone need to turn on the fortran USE flag so that they 
don't break anything?   May I also add, the USE flag description is 
worth about as much as a screen door on a submarine.

fortran - Adds support for fortran (formerly f77)

That doesn't tell me very much.

Heads up for folks about to do their updates, check into the USE flag 
fortran to see if you need to add it to yours before updating a bunch of 
stuff.

If I had to guess, I'd say =sci-libs/blas-reference-20070226 requires
fortran (ebuild depends on it) and you don't have another fortran
compiler installed.

Could be wrong though.

That's right,

blas-reference is written in fortran.

We restructured the dependency chain for fortran support, which includes
a compile test now. The failure can be seen above.

The Problem was in short, USE=fortran was enabled by default for linux
arches, but people tend to disable it. Depending on gcc[fortran] doesn't
work completely as gcc:4.4[fortran] and gcc:4.5[-fortran] with gcc-4.5
select can be installed, which would full fill the dependency but
nevertheless doesn't give a working compiler.

So now packages depend on virtual/fortran and use an eclass to check for
a working compiler. So if you see this message, this means you somehow
worked around gcc[fortran].

One little note,

if portage requests that you should install dev-lang/ifc instead of
gcc[fortran], you most probably have an entry

sys-devel/gcc -fortran

in

your /etc/portage/package.use

Just remove that.

I noticed that if you don't add fortran to your USE flags and something
needs fortran, unless your profile is 64bit no-multilib, portage chooses
to install dev-lang/ifc, for which it downloads a huge (272MB) tgz file
(l_cprof_p_11.1.072_ia32.tgz) containing rpms like:

l_cprof_p_11.1.072_ia32/rpm/intel-cpromklib072-11.1-1.i486.rpm

Uninstall sci-libs/blas-reference I guess.  And probably whatever 
depends on it.  Please do an "emerge -pv --depclean blas-reference" and 
post the output so we can see what's pulling it as a dep on your system.

I didn't have fortran in my USE flags at all, yet portage requested to
install dev-lang/ifc

This is a strange artifact. All my test show that gcc[fortran] should be
emerged. Does it work if you manually emerge gcc with USE=fortran?

I found the culprit. It should be fixed now, so please resync later
today and everything is normal again.

Was ifc pulled in as a dependency for another package?

Yes, I have added fortran to /etc/make.conf (global) USE flags and then
portage didn't ask for dev-lang/ifc.
The profile is default/linux/x86/10.0 and it is chrooted.

Probably not directly, but as as a fortran requirement.

Here is the output:

root@fireball / # emerge -pv --depclean blas-reference

Calculating dependencies... done!
   sci-libs/blas-reference-20070226 pulled in by:
     virtual/blas-1.0

 >>> No packages selected for removal by depclean

Two things.  I read about this on -dev but didn't realize it was going 
to affect me until I saw the message.  After I added fortran to my USE 
line in make.conf, it only rebuilt gcc then revdep-rebuild rebuilt 
dev-lang/ifc-10.0.026-r1.  Everything appears to be clean now.

To think people wonder why my USE line is so big.  I keep having to add 
stuff when portage pukes but portage never tells me when one has fell 
off the reservation and needs to be removed. < sighs >  Over the years, 
it adds up.

That's because those are global flags. If you set package-specific flags
in /etc/portage/package.use, eix-test-obsolete will tell you when entries
can be removed.

That is no solution.  I highly doubt you need a Fortran compiler :-/  By 
adding more stuff to your make.conf as a work-around for problems like 
this, you add more and more stuff to your Gentoo install; stuff you 
actually have zero use for.  By that logic, you could enable every 
possible USE flag that exists so that you always have everything, just 
in case.  But then you should probably be using openSUSE or something :-P

I'm a bit surprised more people here haven't embraced package.use.
It really allows for a high degree of fine tuning, and without it 
the system would be horribly bloated like most other linux distros.
In fact, USE flags are (IMO) what sets gentoo apart and it's one of 
the the main reasons I switched to gentoo from FreeBSD for my main 
systems...

The first time I tried gentoo ithough I was utterly defeated by my 
lack of understanding of USE flags. Then I read the handbook and it 
all came together like magic. :)

IMO the USE line in make.conf really should only contain the universal 
stuff you can't live without, specifying everything else on a per
package basis is what makes it possible to run a system which is at once
full-featured and lean.

As with everything in life, YMMV.

But when something new comes out, I usually want to add it for all the 
packages.  I have a few things listed in package.use but I don't want to 
clutter the crap out of it and then have two files that needs cleaning.  
I have used the eix-test before but it seems to have waaaay to much 
output and it seems something changed and it makes less sense to me 
now.  Maybe I need to give it another whirl and check into some output 
options.

It'll have to wait until after garden time tho.

This is my one strange, mystery global use flag. It's been turned on
in make.conf on every Gentoo machine I've run since I started with
Gentoo in 2002. I've been paranoid to turn it off! :-)

Well, it appeared to only affect gcc here.  We all know I have to have 
that.  lol  Do you really want me to send you my USE line in make.conf?  
I copied it from my old install on another rig and it has been added to 
ever since oh about 2003.  It has some size to it.  Keep in mind, they 
didn't have package.use for a long time too.

I really need to clean out some stuff but want to have time to finish it 
when I start.  I don't have that sort of time during garden season.  I 
need food more than I need a puter.  ;-)

If eix-test-obsolete is outputting waaaay too much there there's an
opportunity there for you to clean things up, if not today then over
time. Once you get it right it outputs almost nothing.

Note that I run stable and then use ~amd64 in package.keywords rather
liberally where I currently have 20-30 testing packages selected.

I haven't cleaned anything up in months.

I suppose you got the idea by now ;-)  Do you need dev-lang/R?  If not, 
then "emerge -pv --depclean dev-lang/R".  Do you need the package(s) 
that this brings up?  If not, continue --depclean those until you reach 
something that has no other dependencies; meaning you reached the top 
level.  Do you need *that*?  If not, unmerge it, then depclean 
everything (just "emerge -a --depclean".)

This should get rid of all stuff you don't actually need/want.

GCC is a compiler collection.  You usually only need gcc and g++. 
Fortan, Objective-C, Objective-C++, ADA, Pascal, Java, whatever else is 
usually something you don't install unless you know you need it.

What is your make.profile?

Here it is not set:

Although gcc seems to have it hardcoded:

Use a directory for package.use, it makes it far easier to manage. All
of /etc/portage/package.* are directories here.

Yeah, I don't suggest I need it. I'm just saying I've had it selected
for nearly 10 years. I think it was in a lot of example docs, as Dale
say, waaaay back. I put it in mine and just left it there. It became
almost a superstition with me! ;-)

As I am a user type and not a dev, I didn't know then, and actually
don't now, that something on the system isn't actually programmed in
Fortran and that removing it would cause a problem so I've just left
it in forever. It never seemed important enough to go figure out since
it only directly effected gcc ebuilds which is a big build and not
done very often.

I guess I can stop playing scaredicat and remove it. :-)

Time is the problem right now.  I got about 50 mater plants, 15 
eggplants, about 100 pepper plants of different kinds, three rows of 
okra, two rows of peas, and just planted three rows of snap beans, 16 
hills of squash, 5 cucumber hills, 5 cantaloupe hills, and a few others 
that I forget.  Did I mention I have nutgrass?  I make rounds every day 
for that.  THAT is some work.  Since it just rained, it will be popping 
up real good now.  This next week will be so much fun. < roll eyes >

I did have a time that it returned nothing.  It took me several days to 
get there tho.  Right now, I don't see that happening.  What would be 
nice is if portage would print a little message when a USE flag goes 
away.  It does a good job of letting us know when one is missing.  It's 
half way there now.  lol

Short version since it is sooooooo long:

root@fireball / # eix-test-obsolete -d | grep Found
Found 19 matches.
Found 8 matches.
Found 41 matches.
Found 2 matches.
Found 28 matches.
Found 354 matches.
Found 4 matches.
Found 27 matches.
root@fireball / #

354 !!  That could take a while.  O_O   Maybe start on the small ones 
first.

But gcc is the one that got rebuilt when I changed the USE flag.  So, it 
needs it because the other package needs it and in the end, KDE needs 
all that stuff.  So, the flag is added and I guess it is needed by 
something I want to keep.  Sort of like my GUI and all.  ;-)

Funny thing is, it appears the dev changed it back so after the next 
sync, I can shorten my USE line by one flag.  Progress.  lol

I have done that for package.keywords and unmask.  In ways it is easier 
but in ways, it is a nightmare.  If something is unmasked, I have to go 
find the file that unmasked it.  I have several since I use autounmask 
for most of it.  Then add in that the new autounmask part of emerge 
seems to pick a random file to add too.  At that point, not much makes 
sense anymore.

I think the dev added it back.  So, if you really don't need it, put the 
minus sign in front.

If you use KDE like me, be prepared to put the thing back tho.  Some KDE 
packages depend on things that seem to need it enabled.

And KDE wants Fortran because you have that USE flag enabled in 
make.conf :-D

I'm on KDE too, and it doesn't need it.  Probably because my make.conf 
explicitly says "-fortran" in it.

Actually, for me it's a non-issue. I've had it in all along. Even when
I remove it from make.conf and package.use it still shows up in gcc:

c2stable ~ # emerge -pv gcc

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] sys-devel/gcc-4.4.5  USE="fortran gtk mudflap
(multilib) nls nptl openmp (-altivec) -bootstrap -build -doc
(-fixed-point) -gcj -graphite (-hardened) (-libffi) -multislot -nocxx
-nopie -nossp -objc -objc++ -objc-gc -test -vanilla (-n32%) (-n64%)"
61,647 kB

Total: 1 package (1 reinstall), Size of downloads: 61,647 kB
c2stable ~ #

so nothing is getting rebuilt on my system by removing it. As not
every system here uses the KDE profile I'll investigate removing it
later, or just leave it in case they start using KDE.

Cheers,
Mark

That's actually the correct statement. When I removed the fortran flag
it didn't change anything because (I suppose) the KDE profile has
included it as a default.

R is a mathematical language similar to Matlab/Octave... only
specialized for statistical computing. I assume if something in KDE is
using that it must be optional; check your USE flags.

Actually, I didn't have it in there until the update this thread 
references back too.  It was there by default but it was removed by a 
dev and portage puked.  So, maybe I need to do -fortran and see what 
happens.

Mine never had fortran in it at all.  I still don't really know what 
fortran is.

Well, I don't have fortran use enabled

mail-proxy ~ # euse -i fortran
global use flags (searching: fortran)
************************************************************
[-      ] fortran - Adds support for fortran (formerly f77)

local use flags (searching: fortran)
************************************************************
no matching entries found

However, kde-base/kde-meta-4.6.4 pulls in kde-base/kdeedu-meta-4.6.4
which pulls in kde-base/kantor which pulls in dev-lang/R (since my profile
has the R use flag enabled) which pulls in virtual/blas which pulls in
sci-libs/blas-reference-20070226 which then craps out since I don't have
the fortran use flag enabled.

My solution is to force -R in make.conf

It's a programming language.  You know, C, C++, stuff like that.  Except 
that it's a zombie-relict from the 1950's that refuses to die because 
people still programming in it are too lazy to learn a proper, more 
modern language :-P

When you enable the fortran USE flag for GCC, you are telling it to 
compile and install the GNU Fortran compiler.  Sometimes USE flags can 
have more dramatic effects than just enabling some extra functionality; 
in this case for example, a whole compiler and supporting runtime 
libraries are built and installed.

That was what I liked about autounmask, the tree version not the portage 
one.  It gave them some names at least.  Still felt like looking for a

Well he double hockey sticks.  That's why gcc compiles faster when 
fortran is disabled.  :/   Now I know.  I wasn't even born in 1950 so I 
had no clue.  Dang, that was when puters were made out of vacuum tubes.

When I did that, it complained that cantor was built with no backend.  
Did you get the same thing?  It said this here:

WARN (postinst)

You have decided to build cantor with no backend.
To have this application functional, please do one of below:
     # emerge -va1 '='kde-base/cantor-4.6.4 with 'R' USE flag enabled
     # emerge -vaDu sci-mathematics/maxima

So, I did the later and it needs to emerge several packages that I 
didn't have before.  Looks like I can either have a bit of bloat on one 
side or a bit of bloat on the other side.  o_O

I mention just in case you didn't notice the message and then something

Do correct me if I'm wrong, but wasn't blas-reference pulled in by
merging gcc with USE="fortran"? Or did you install blas-reference for
another reason?

Fortran put Armstrong on the moon.

NASA wouldn't dare let Windows try that, they take one look at Air 
Traffic Control or nuclear submarines or Aircraft Carriers or even, 
god forbid, Airbus's latest and greatest, and know exactly what NOT to 
do

Yes, it complained about the same thing.  Since I don't know what cantor
is I figure I don't much care if it has a backend or not.  :-)

Seriously, I haven't noticed any issues yet not having the backend.

If I find something broken I need then I'll do as you did.

No clue.  I just -c'd some stuff and kept running revdep-rebuild and 
emerge -uvDNa world until it all got sorted.  It took a few times but I 
finally got a clean result.

The funny thing is this.  I removed about 3 packages but had to install 
close to a dozen to satisfy what was missing.  Cantore, or something 
like that, was left with no backend when I removed R.

So, removed some bloat then installed some more bloat.  Ain't that a peach?

For kicks I decided to give -fortran a try. I find it interesting that
with Fortran installed using either the fortran flag in package.use,
or just not setting the flag at all, I apparently do not need the c++
libraries that I do need when I choose -fortran. However it seems that
-fortran doesn't eliminate the need for installing a Fortran compiler.
It simply shifted it from the GNU gcc Fortran package to the Intel
Fortran Compiler (dev-lang/ifc)

c2stable ~ # emerge -pvDuN @world

These are the packages that would be merged, in order:

No actually blas-reference fails to build unless gcc is built with the
fortran use flag enabled (since there's no fortran compiler available.)

The deps pulling in blas-reference are in my previous mail.

I have a calculator I got from Radio Shack when I was in high school.  
It's a EC-4020.  I read it has more computing power than the puters that 
were on Apollo or something to that effect.  It's hard to believe they 
had such whimpy puters but could do so much.  Funny thing is, I'm not 
sure we could go to the moon now.  I know I wouldn't get on one.  Then 
again, I don't fly either.  I have told people that if they see me on a 
plane, close the lid on my coffin.  That's the only way I would get on a 
plane.

It's amazing how far things have come but how far off some things still 
are.

Hi justin.  Just want to say thanks for being a gentoo dev, and even

If you have virtual/fortran installed then portage will pull in a
different Fortran compiler. (ifc on my machine)

I emerge -C ifc and revdep-rebuild rebuilt some stuff but it is gone 
now.  So, you may have to work with it but it *might* be removable too.

I think the point we're trying to arrive at here is why you need a
FORTRAN compiler installed in the first place. Given that you didn't
even know you needed one until recently, it seems odd that you've
installed packages that require f77 to build.

Did you install R on purpose? If not, what pulled that in, and did you
install *that* on purpose?

Odds are one of your 1.5quadrillion USE flags is pulling in FORTRAN when
you don't even need it.

Maybe we have something different then.  I don't have blas-reference on 
here anymore either.  My point was, disabling fortran to remove it only 
lead to other stuff being required.  I think there is more on here now 
than there was before.  So, removing fortran to get rid of bloat didn't 
help any because it just required a different set of bloat.

The odds of you ever needing to use cantor are practically nil. And if
you did, you'd probably already have R installed and know what FORTRAN
was.  So, don't worry about it.

So why are you installing it, and all its dependencies, on the one hand,
and complaining about bloat on the other? Surely installing stuff you
don't need is the very definition of bloat.

Thanks Walt,

the user list is a valuable source to get a feeling what is going on.
And to catch bugs and breakages quickly. When changing things, it is not
always possible to foresee everything and thus things like this fortran
breakage occur. So it is always good to follow what happens to the
broader audience.

In the end of the day we are all user,

Hi Dale,
   For me this was more about following along with the thread and
learning about this flag. I had no real intention of changing
anything. I do use R in Windows & sometimes in Linux so apparently I
need a Fortran compiler. I see no advantage and many disadvantages to
switching to ifc from gcc-fortran so I'll just leave things alone.

Cheers,
Mark

But it installed stuff either way.  Instread of ABD, I got WXYZ because 
of dependencies.  It's not that I want them, it's that portage needs 
them to make a package that I do want happy.  This reminds me of the six

My question was why are you installing cantor if you don't need it?

You don't use it, you don't need it, it drags in a bunch of dependencies
that require other packages to install more files too, yet you still want
it there.

Hint: I don't have cantor installed and the sky hasn't fallen in, at
least not yet.

Oh, I see.  It was pulled in by kde-meta.  I know I can have KDE other 
ways but it is much easier to emerge kde-meta than to emerge < some huge 
amount of packages >.  There are times when I am looking through the 
menu and find something interesting that I didn't know about before.  So 
far, Cantor isn't one of them.  lol

Yes of course.  Sorry for the imprecise statement.  But the point is my
profile turns on R by default so just by emerging kde-meta I end up with
the GCC fortran compiler and packages that require a fortran compiler.

And if the fortran use flag was turned off (either by changes on ~x86 or
if I turn it off myself) then I get build failures.

It seemed ironic that a recent training helicopter crash near here
resulted in the survivor being taken off in an air ambulance helicopter.

Though most of those I know of are twin engine turbines so chances are
good you won't lose both engines at once...

Helicopters are for those who are pigheaded enough to want to beat the
air into submission.  :-)

Agreed 100%.

It's very strange (to me) that kde-meta builds R at all. TTBOMK it's
not even remotely a KDE project and of absolutely no value that I can
see to the average KDE desktop user. I run R, mostly in a Windows VM
because I prefer the GUI, but sometimes in Gentoo also.

The "Scorpion 2" helicopter kit ads in my dad's Popular Mechanics mags 
way back in the day made a big impression on me. Way more risky than 
a simple fixed wing or autogyro, and not terribly fuel efficient
either...

It refuses to die because it's still very useful in certain niche areas

I saw a guy on a TV interview once.  He said the only way a helicopter 
can fly is by brute force.  A airplane wants to fly but a helicopter 
just wants to crash.  He said that can be proven by taking your hands 
off the controls.  Down it goes.

Having twin engines does help tho.  I just don't like the cheapest

either.  That is really true on my brakes.  That I want good stuff for.  
I want good brakes even if the engine runs like crap.  I can always stop

Well, it was working before just fine.  I was able to plead ignorance 
until the dev changed the USE flags on me.  That's when it hit the fan.  
I was better off being ignorant on this one.  I could have left it the 
way it was and looking back, maybe I should have.  I dunno.

True, that's why helicopters are more risky -- especially a home-built
single-engine ultralight helicopter. But the maneuverability is amazing 
in the hands of a well-trained pilot.

Of course there's a place for Cobol, a classic one is in the bank my

I use sets for this. I want KDE but not all of it, so I have a set 
with just the -meta packages I want:

When I stand on the balcony at work having a smoke, I look straight at 
the only helipad within 30 miles (there is one more in the CBD, but 
it's strictly medical airlift only). Below my feet is the entrance to 
the parking garage.

My house has a flat roof, wouldn't take a lot of effort to erect a 
platform over it.

See where I'm going with this?

I was seriously considering importing a single seater heli kit, they 
are classed as ultralights and do not need a pilot's license. But 
there's an obscure clause in the rules that states ultralights cannot 
be flown within 50m of a dwelling.

So now I have to be content with only going to work on the V-twin bike

We won't ask :-)

Heli pilots are insane, but have serious flying skillz.
Interceptor pilots are not even human, but then again if you bolt a 
big enough engine onto a brick, it will fly too.

Wow, how do you maintain that lot and keep it all straight?

KDE devs love adding and removing and renaming stuff between minor 
versions, mostly just for the hell of it. You could end up with 
KDE-4.2 packages in there if you don't keep an eye on it :-)

I'm with you, Dale. I have no /etc/portage/package.* directories here on 
this amd64 box - I just keep entries in alphabetical order in single files. I 
find it easier.

I've also found it much easier to manage flags etc by setting the kde profile 
(this being a kde box, of course - gnome is too arrogant for me). It makes 
for a nice, simple USE line in make.conf.

So it seems. I've just tried "USE=-fortran emerge -upDvN world" and the only 
thing that would be remerged because of fortran is gcc. So I'm going to put 
-fortran into make.conf and see what breaks.

My point was, you can install cantor without R (or maxima) and it will
complain loudly that "I'm installing myself broken!"... but it *will*
install. And if you never run it, you never need R, thus you never need
+fortran, and your gcc will be much happier.

"FORmula TRANslator". it keeps your lights on, as likely as not. Last I 
looked, electricity power grids were kept alive with fortran doing the

The KDE ebuilds barf if you try to mix versions, if a package is removed
or renamed from a later release, portage lets me know!

If means I don't get to know about any new additions, but I can read
about those on kde.org

That doesn't help with linked packages with different names. If foo
requires libbar with USE="snafu", I put it in/etc/portage/package.use/foo
Then if I remove foo, I remove the use file. If they were alphabetically
sorted, and therefore separate, in one file, I wouldn't make the
connection. And I don't have to worry about sorting package.use every
time I make a change, ls does that for me.

It may not be. I have only four USE flags in make.conf, and still I have the

It will break several things.  This is what I just went through.  It 
appears that if you emerge kde-meta, you have to have a fortran type 
compiler.  So, you may as well keep what you got if it is working.  When 
I started going down this road, I thought I could just disable fortran 
and have less packages installed.  That is not the case.  I removed 
fortran then had to replace that with even more packages than I had to 
begin with.

If it works with fortran turned on, I'd leave it alone.  With hindsight, 
I should have left well enough alone anyway.  It wasn't hurting a 
thing.  Watch the elog messages.  It will tell you at some point to 
either enable fortran or emerge some other package that I forget the 
name of.  That one package pulled several dependencies on my rig.  YMMV.

Just my $0.02 for whatever that's worth.

My method is to put a USE flag into make.conf if it's described in use.desc; 
otherwise it goes into package.use if it's in use.local.desc.

Seems to keep me out of trouble most of the time.

I was hoping to trim a little fat not break things.  I may never need 
cantor but if I do, I would like it to work without me having to figure 
out why it is broke.  Plus, next time a upgrade comes along, I got 
issues again.  It's going to pull in a update that fails to compile and 
its going to upset me greatly, much more so than having fortran or 
whatever installed.

Maybe you wasn't around during the GREAT hal and xorg mess I ran into.  
Trust me, it wasn't steam, it was flames.  I would like to avoid that.  
I wanted to wring that nerds neck for rendering my keyboard and rat 
useless.  :-@

Maybe it's time to make a backup, then remove all USE flags from make.conf 
and package.use, set your profile to default/linux/<arch>/10.0/desktop/kde 
and rebuild. Alan and Neil's idea of a set of the meta-packages you want 
sounds good to me too.

Then you'll really have a clean system.

I may follow suit - I built this system with kde-meta for simplicity, but of 
course it now has a lot of stuff I don't want, including Fortran. I tried 
rebuilding with -fortran as I said a few minutes ago, but portage wanted ifc 
instead.

I install with kde-meta.  It pulls about all things KDE in with that.  
For me, it is better to use kde-meta than to do it any other way.  Even 
with kde-meta, I think there is a few that I still had to emerge manually.

YMMV tho.

You will have whatever system the profile maintainer thinks the 
average user should have, bloated to whatever degree said maintainer 
thinks is a good idea.

No USE flags set does not mean no options set, it means default. And 
default sets plenty flags ON

kde-meta gives you all the stuff that's useful on the average system, 
plus all of accessibility, kdebindings, kdeedu, games, the sdk, toys 
and maybe even webdev.

I can't think of the kind of user that truly does actually need all of 
that.

It's one package (cantor) that has one dependency (R) that is optional
(USE=-R) that falls squarely into the "if you aren't sure if you need it
then you probably don't" category. So for most users, no, you don't need
to build gcc with fortran. Dale's just playing it safe, I guess, after
the admittedly scary "I'm all broken and stuff!" warning message cantor
throws at you.

kde-meta say (to me) 'I want everything KDE has to offer'. This seems
completely inconsistent with 'I was hoping to trim a little fat'.

An occasional use of eix-test-obsolete does well enough for me. I ran it 
just now after several months, and it found one redundant entry in 
package.keywords (for libreoffice).

I don't sort it; I put entries in in the right order to start with. An 
occasional entry put there by autounmask is demarcated anyway, so they're 
easy to see, and to delete when no longer needed.

It works well for me, but we all have different foibles.

Yep.  On my machine, it pulled in about a dozen or so new packages to 
replace R and fortran being disabled on gcc.  I'm not sure I made my 
system any leaner or cleaner.  I actually may have done the opposite.

Yes, of course. My point is that you can forget about maintaining all those

I know, and I used to take the time to find all the things I did want and 
just install those. I used kde-meta this once just from laziness. Now I get 
to keep the whole hog-roast.

Me neither. So maybe the time's approaching when I go and slim the whole 
shebang down. It'll have to wait until I've finished the current round of 
redesign of my website though. 177 pages to modify - that should keep me off 
the street corners for a while.

  Actually, it was what non-professional programmers used before
computer spreadsheet programs existed.  It was just the thing for
crunching numbers and text.  It was because it was used by
non-professional programmers that so many old Fortran programs are
spaghetti code.  A properly-written, structured Fortran program is quite
usable and easily followed.

"package.accept_keywords"?

2) what does "package.env" do?

3) does "package.cflags" specify package-specific cflags?  What about

  Years ago, I changed to starting my USE line with "-*" and adding what
I needed, either in /etc/make.conf or in /etc/package.use.  This was
right after ipv6 was added to the defaults.  The ipv6 fiasco was "an
interesting experience", to say the least.

I use that as a general rule too, although there is the situation where a

That's not the only one. Digikam has a hard depend on clapack, which
requires virtual/blas and thus a Fortran compiler.

Well, as I said in another post, I do have -fortan in my make.conf and 
there are no problems.  I do not have programs installed that need a 
fortran compiler.  And I do not have kde-meta installed; that's a waste 
of resources.  I only install what I actually need.

I seem to recall you having -fortran all the time tho.  It's the change 
that breaks things.  I mentioned it in case he is using kde-meta since 
it should pull in the same packages as on mine.  If that is so, he will 
end up with broken stuff and will need to fix them.

This is one of those situations where it depends on what you have 
installed and if you are changing something.  This doesn't apply to 
everyone just those have not had -fortran set before and installed kde-meta.

This may not apply to you but it may apply to others.

Mine isn't sorted, but it's only 20 items or so and it's grouped into "categories" of related programs. A few months ago I cleared out entries for a few programs that I no longer use - I would guess I will notice to do so again in another year or so.

Any packages which are listed because they're dependencies of something else, I add that as a # comment at the beginning of the line.

I like the idea of package.use as a directory of indie files, but haven't bothered switching over because this works so well for me. The package.use directory system seems too simple to be true - is it really no more complex than a directory of any-named files of the same format?

What seems strange then is that if everyone keeps telling Dale that he
most likely doesn't need cantor and R then why is R enabled in the
profile by default?

Seems it should be -R by default?

Hrm. I installed kde-meta and it didn't pull in Digikam. But 
I don't remember turning it off (though I would have). I 
have a completely unreasonable and unjustifiable dislike for 
FORTRAN so I go out of my way to keep it off my system :)

Yes, its just directories ... but I switched one system over to it and
ran for a year or so in parallel with systems that are original - I am
going to switch back as its teeing me off big time.

"Sounded a good idea" - sucks in practise, making management more time
consuming and harder than it needed to be for absolutely no gain.  Think
of it this way, do you want to manage one keyword file or dozens.  The
heirarchal idea sounds good, but its just more work, more letters to
type, more files to search for packages, etc.

On a small, heavily managed server it might work, but ...

It's not enabled in the profile, it's enabled in the ebuild:

IUSE="debug ps +R"

and likely for the same reason there's a scary warning. If 
you're installing cantor, because you plan to use it (and 
not because kde-meta is a bloat monster), you need one of 
the two backends to make it work. R is the preferred option 
there, so the cantor maintainers assume "if you want cantor, 
you probably want R", and the cascade begins.

I saw that before and got really excited until it dawned on me there's
no way that thing can be controlled the way it's built. :)
No doubt why the only videos he seems to have of it "hovering" it's
tethered. Otherwise it'd surely kill somebody.

He also claims it will achieve altitudes up to 10k feet, which
obviously would require generating a "cushion of air" 10k feet tall.
Because being a hovercraft it's got fans, not rotors.

Or have I missed something?

Or maybe 'kde-meta as currently constructed by someone somewhere is a
bloat monster in some other people's opinions'. And, we're not
required to use it.

Maybe it happens somewhere but I don't know of any truly interactive
user driven process that decides what gets included in any ebuild. It
is driven more by our kind devs by whatever decision process they use.
I'm *perfectly* fine with that.

To some Gentoo users anything on the system that they don't actively
use is bloat. I understand. To others, myself included, I don't mind
if there's a bunch of extra stuff on my system if it makes some
developer's life easier. 95% of what I do in KDE is run Firefox or a
VM for trading futures and the balance is mostly use a terminal to
maintain my systems. I use Skype a little, backup to a few different
external hard drives. Sometimes I play solitaire. Nearly all of my
media watching is done in a VM due to NetFlix not supporting anything
that runs native on Linux, although I do use xine to watch the
occasional DVD from NetFlix that only I want to watch.

I don't share desktops, share or mount anything natively Windows. I
don't use Konqueror or KDE Mail. I use almost nothing in the KDE Menus
for Development, Education, Games, Graphics, Multimedia or Office.

And I also don't care enough to do anything about trying to maintain a
'smaller' KDE footprint on my machine because the code builds plenty
fast and I don't want to use my time that way.

This is just my 'life can be simple' strategy. It works for me and has
allowed me to drop about 40 pounds of bloat in the last 8 months.
Blood pressure is down. I sleep better. I don't sweat the small stuff
as much.

Again, this is just me...

You have no programs, that *need* fortran, but it could well be, that you have 
programs installed, that perform better when compiled with a fortran compiler.
I think of sci-libs/fftw here as an example. It's used by programs like 
blender, imagemagick and maybe some others. The developers of said library use 
fortran, because they benchmarked it. If you disable fortran, you use the 
slower C fallback solution. If you disable fftw in those packages, you get a 
slower implementation too afaik.
After all, gentoo is a source based distribution. We all already have a couple 
of languages installed. There's a C compiler a standard user will never use. 
There's a C++ compiler only used by programmers. We all have them, only to 
compile programs, that need them.
Why not enable fortran, even if it's only optional, to get the best of the 
available implementations? In the end it's only one programming language more 
installed on your system.

Michael

Just to add some further prophecy to this: with GCC 4.6 the gfortran
compiler became a complete implementation of Fortran 2003.  This allows
for Object Oriented Programming (OOP), the fashionable style of
designing code these days.  This means that there could well be more
new software written in Fortran; without a Fortran compiler a user will
be unable to install this code on a source-based distro like Gentoo.

Indeed, the ability to compile as many languages as possible is almost
a necessity for users of a source-based system like Gentoo.

I just wonder if that is why Cantor was set up to use fortran by 
default.  Not because it is smaller, requires a few less package but 
that it is what it is designed to run off of.  It may well work with 
something else but not as fast, not as good or something else we don't 
know about.

Just makes me think again on this one.

cantor uses R as default backend. R uses fortran. And yes, that's because of 
its speed, when it comes to mathematics and numerics.

I put it back like it was.  Heck, if I don't, something else will need 
it later on and portage will puke on my keyboard about it being 
disabled.  As it is now, portage will do what is best since the devs 
tell it what to do.  I know they know more about this than I do.

I guess my first post was correct after all.  Enable fortran USE flag 
and keep things as it was before it got changed.  It was working fine.

Yes, but don't ask me what happens if you have both files.

It's a more logical name, because it contains per-package overrides for
ACCEPT_KEYWORDS, so it now follows the same naming convention as the
other package.* files.

kde-meta is, by definition, a bloat-monster. It's sole purpose is to
install everything KDE you could possibly need without you needing to
work it out for yourself. It fulfils that need well, but if space usage
or compile times are important to you, it is the wrong choice.

I didn't say it would. I meant that installing Digikam also requires
blas-reference, and therefore a Fortan compiler. Digikam is here because
I chose to install it, gcc{fortran] is here as a consequence of that
choice.

Because if you do need cantor, it works best with R. But the point is
that he doesn't need cantor, and therefore not it's dependencies, like R.

  Which brings up the question, why are you using KDE in the first
place?  It's a pointie-clickie-touchie-feelie-oowie-gui that emulates
Windows, but doesn't do anything for me.  I run Icewm as my WM.

You seem to have forgot the dev had changed it.  Since it got noticed 
and all the dev changed it back in about a day or so.  So, it was 
enabled, got disabled by a dev then got enabled again by the same dev.  
That was the reason this whole thread started to begin with, to alert 
people that a USE flag got disabled and SOME of us need to enable it 
again if we want things to stay the same.

ISTR reading some mention of that. Do you mean the profile was changed?
That sounds a bit naughty, changing a profile should be done on a version
bump IMO.

Hi,

as most of you do not like to have fortran enabled by default, we tried
to find a way around. We created a virtual/fortran which should depend
on a working fortran compiler so that only ebuilds which need fortran
compiler will build it. With that situation it was possible to remove
USE=fortran from the profile (btw profiles cannot have a version bump
and don't need it) so that most of you could drop the fortran support
from gcc except a ebuild depends on it.

However I wasn't aware that there is no hierarchy in the dependencies in
an ebuild and portage will choose a solution w/o a USE change first.
That is the reason why many of you saw that ifc should be installed,
instead of gcc with USE=fortran. That was the point where I added it
back to the profile as a default enabled USE.

The solution for the average user is leaving all default USE on. This
will gcc build the fortran support and you will have no problem. (Libs
and compiler are 1.5MB on my system)

Or remove add -fortran to your make.conf and add sys-devel/gcc fortran
to your /etc/portage/package.use.

Trying to avoid any fortran at all is stupid, because as already
mentioned many math operations are faster if programmed in fortran.

Cheers justin

Whether "many" operations are written in Fortran is immaterial. What matters 
to me is whether any on my system are. If they aren't, I don't need a 
Fortran compiler and I'd rather not waste system resources on building one.

Feedback from the consumer end of the producer-consumer link :-)

The motivation is fine and well, it didn't quite work out, we call 
this a "bug".

The only real mistake was trying to slipstream it in without 
notification or warning. devs all agree we should never do this, but 
it is so ... tempting.

I've made the same mistake myself many many times, and each time it 
came back and bit me hard :-)

Try euse -I fortran.
If anything besides gcc pops up, you should have one.

What I like is the speed it got corrected.  People that don't sync often 
most likely didn't even know it ever changed.

Another like, a dev that at least reads some of this stuff on -user.  
It's a good way to get feedback.  If you change something and it doesn't 
get mentioned, most likely all is well.  If it does get mentioned, may 
want to rethink the change.

I am getting confused:


$ euse -I fortran
global use flags (searching: fortran)
************************************************************
[+  D   ] fortran - Adds support for fortran (formerly f77)

Installed packages matching this USE flag: 
sys-devel/gcc-4.4.5

local use flags (searching: fortran)
************************************************************
no matching entries found


Two days ago or so, virtual fortran installed itself.  A day later it 
uninstalled itself.  Now fortran is set in USE as default.


I don't know if the film I was watching on TV about aliens has something to do 
with this, but I seem to have lost some time ...  ;-)

Yes. He's saying they didn't change the USE flag, they 
changed the fortran dependency test to actually do a 
run-time check for fortran because the USE flag alone wasn't 
sufficient.

Which means you most likely had a non-working cantor and no 
fortran compiler before and just didn't notice :)

I got bit, on a 6 monthly major update across multiple systems - what

Despite that, its small potatoes in the scheme of updating perl/python

My understanding, USE flag was there and had been for a long time, got 
changed, this thread was started, discussion was had, USE flag was put 
back the way it was.  So actually it was only not working while I was 
messing with it.  That would be true ONLY if you were using the 
defaults.  If you had -fortran then nothing should have changed as would 
having fortran enabled.  It was only folks like me that didn't have any 
mention of fortran that were affected.

Just one of those things.  ;-)   As someone else posted, this was minor 
compared to some things we have ran into.

Please don't bitch out the devs - we have few enough of them as it is.

I have a number of bugs open (on b.g.o), one or two of which have not moved in months. The others are newer, and I assume they're are not going to get fixed much faster, and I assume the reason is that there just aren't the developer resources available. I mean, I could assume that the devs just hate me, but that seems a pessimistic attitude. I'm pretty sure they're not breaking things out of spite.

None of my bugs are fixed as easily as recompiling a couple of packages - I don't whine about trivial stuff like that - they all require manual intervention and that I modify ebuilds myself and keep them in local. I sunk several hours into this this weekend.

I would be glad to bitch out the devs and say "why aren't you doing it this way?", "why isn't this fixed yet?" but I don't feel I have any right to. I'm reserving bitching out the devs until I can afford to pay them money on a regular basis. What's your entitlement?

That doesn't appear to work like it should then.  I get this:

root@fireball / # euse -I fortran
global use flags (searching: fortran)
************************************************************
[+ CD   ] fortran - Adds support for fortran (formerly f77)

Installed packages matching this USE flag:
sys-devel/gcc-4.4.5

local use flags (searching: fortran)
************************************************************
no matching entries found
root@fireball / #

Thing is, I know a couple packages use it on this rig because I just had 
to recompile them.  Cantor and R are two that I recall.

Maybe it is because it is not a option in the list?  The USE flag that is.

Iirc you had problems with -fortran, because you have packages that really 
need fortran. My suggestion was for people like Peter, who have no problems 
without fortran. It shows only packages which could perform better, if a 
fortran compiler is available and otherwise fallback to a C implementation. At 
least, I think it does :)

Thing is, I switched it back and programs on here now need fortran to 
build.  So, euse is not reporting it but R and Cantor won't build 
without fortran.  Basically, euse should also report R and cantor but it 
isn't.  If mine isn't reporting that, then Peter's may not either.

That's because R needs a fortran compiler to compile. It does not have a C 
fallback solution for its maths. cantor depends on R per default. So it won't 
build until a working R is installed.
Peter is not having problems without fortran. Everything compiles fine. So I am 
quite shure he has neither R nor cantor installed or any other program that 
needs a fortran compiler to build at all.
This euse command shows only packages where fortran is optional. This means 
better performance, when enabled, in all (at least almost all) cases.

That's impossible, I think. euse reports USE-flags. These programs don't have a 
fortran-USE-flag. R needs it unconditionally..

Neither of those packages has a "fortran" USE flag, and 
cantor doesn't "know" anything about FORTRAN.

cantor has an R USE flag, to switch it's R backend on/off. R 
doesn't have a USE flag for FORTRAN because that would be 
pointless -- it *requires* an f77 compiler, so it depends on 
virtual/fortran unconditionally.

You would probably be better off using

root@platypus ~ # equery depends virtual/fortran
dev-python/numpy-1.6.0 (lapack ? virtual/fortran)

You will probably have both R and blas in that list as well. 
If so, you will need to continue to enable gcc[fortran] to 
build those.

(The fact that gcc has a fortran USE flag is only relevant 
because it's the default compiler; you could also 
potentially have ifc installed to satisfy virtual/fortran, 
rendering gcc's USE flag irrelevant.)
