[gentoo-user] Can't emerge gnash

[gentoo-user] Can't emerge gnash

[Ezequiel Garcia]

Hi,

I was trying to emerge gnash but failed. Here's the output....

The problem seems to be boost_thread not present. I'll try to emerge
that, but in any case this
looks like a gentoo bug in gnash ebuild.

If anyone helps me filling a new bug, I'll appreciate it.

Thanks!

It seems this is a different bug.

Before filing a new bug, I should do emerge --sync,
(to have latest ebuilds), right?

I wonder why they've used boost! (I'm not a big fan of it)

Ezequiel.

For me, I'd go:

# In case there's something already broken I don't know about.
revdep-rebuild

# Remove 'theoretically' unused versions of things.
emerge --depclean

# Because we ran --depclean, something may now be broken.
revdep-rebuild

# does an emerge --sync
eix-sync

# Perhaps specify the particular package, instead of @world
emerge --update --deep --newuse @world

# Again, remove old versions of things.
emerge --depclean

# Again, because --depclean can break things.
revdep-rebuild

...and then see if I can reproduce it.

Boost probably had some code in it they didn't want to reinvent
themselves. It's also pretty common, which makes things easier for a
developer who wants to get into more distributions' repositories.

Of course. But then again, this is arguable.

In theory reusing code is a great thing,
in practice I've seen it leading to big bloating problems.

Also as a developer I don't really like to force my users
to have a monster library installed to use my code.

But that's just my humble opinion.

Developer here, too. Mostly C++ on Windows, though I far prefer the
way Linux does things. :)

In theory, using in-house code seems like a great thing. Having
written it, I understand it, I understand its API, and it's not a big
blob of unknowns for me to fear when debugging my programs.

In practice, I've seen more time (and money!) spent reinventing the
wheel for any given project than it would take to pull in a library.
I've seen and participated, designed and/or led in the redevelopment
of locking mechanisms, nested image compositing engines, database
abstraction layers, deferred I/O abstraction frameworks and probably a
half-dozen other things I'm forgetting right now.

Each and _every_ time, a great deal amount of developer time is
consumed at the outset with development, and then over the life of the
code as bugs (some of which simply come from underestimating or
misunderstanding the resulting complexity of the system) turn up.

NIH costs. I'd rather use a widespread library than write my own,
wherever possible.

But, of course, that's just _my_ humble opinion. And each circumstance
warrants its own cost/benefit analysis.

  Change the jobs option in /etc/make.conf to 1, i.e...

MAKEOPTS="-j1"

  You'd be surprised how many "unreproducable" bugs that fixes.  I
simply leave it at that setting all the time.  Yes, it takes a little
bit longer to build, but the compiled binary runs just as fast.  And any
time you "save" building will be lost the first time you spend a few
hours trying to figure out mysterious build failures.

This is off-topic now :-( But it's a nice discussion :-)

I agree with you mostly. I think you're a bit biased against
rolling-your-own, perhaps
because working on windows enforces that -there are less open
libraries/programs you can reuse-.

Again, it's a great thing to re-use and it's evil to reinvent the wheel.
It has all sorts of advantages, we all know that.

On the other hand, as you say, each circumstance needs its own analysis.

Let me use an example: I'm writing a middle-size application in C++ that
will run on an embedded device, linux only.
Let's say I need some threads and some mutexes.
Heck, I'm not going to use boost if I can just wrap pthreads around
some lightweight classes.

Ezequiel.

In that circumstance, you're mostly going to be distributing firmware
blobs. I'd probably rip the relevant code out of boost (perhaps set up
a script to do this), drop it somewhere in my project folders, and tie
it in with my build system. Respecting, of course, the license
requirements of boost.

It's unfortunate that boost's build system isn't modular, and
especially that it won't parallelize. I'll probably look at it at some
point to figure out if I know enough to rewrite it in autotools. I
could totally see a "--with-this-module=yes" per-module, as opposed to
an "--enable-all" for those users who don't know which parts they do
or don't need.

It's something that needs to be done. The question is who's going to
have the time and inclination.

Good observation. I usually look at the build log and file bug reports
when I see that happen. It can take a while to learn to recognize, but
it usually takes less than a minute to spot. I could probably automate
it with a shell script and grep. Hm.

(Parallel building cuts my build time for a full system two a mere few
hours, IIRC. A serial build of a full system takes could be started
before I go to sleep, and wouldn't be done before I went into work the
next day.)

(I tried tricking genlop into giving me the build time of an emerge
-pe by putting -e in EMERGE_DEFAULT_OPTS, but it appears to be hung.
:( )
