This is not, in the general case, a good idea.  This will enable the
static-libs USE flag for *every* package except those that have an
explicit -static-libs flag specified.  This will populate /usr/lib
and /lib with a plethora of *.a files that will never be used.

The static-libs USE flag should only be enabled on a case-by-case
basis, by specifying the package(s) in /etc/portage/package.use.

[gentoo-user] I can't understand an emerge error. Help, please!

[Alan Mackenzie]

Hi, gentoo.

When I try to run an emerge world, I get this error:

# emerge --update --deep -p world

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

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy "dev-libs/libgcrypt[static-libs]".
!!! One of the following packages is required to complete your request:
- dev-libs/libgcrypt-1.4.6 (Change USE: +static-libs)
(dependency required by "sys-fs/cryptsetup-1.1.3-r3[-dynamic]" [ebuild])
(dependency required by "sys-apps/hal-0.5.14-r4[crypt]" [ebuild])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])

What is this saying?  That I need to locate a use flag "static-libs" and
change it for package libgcrypt?  Presumably it is libgcrypt which is
dissatisfied.  I'm having difficulty parsing the mssage.

Next question: what should I do about it?

Thanks for the help!

One of the packages in your world requires dev-libs/libgcrypt which
was built with the "static-libs" USE flag. So, the line above is
telling you to add "static-libs" to your USE flag for that package.

These are the items that require libgcrypt with static-libs USE flag
set. Sometimes changing USE flags on thse packages will change the
dependency requirements. Sometimes it's just something new that the
maintainer added since a previous version.

If you don't already have one, you can set package-specific USE flags
in /etc/portage/package.use and in this case you'd add a line:
dev-libs/libgcrypt static-libs

OK.  I was getting confused by "dependency required", which sounds
tautological.  What it seems to mean is "package required".

I've done that.  It works.  :-)

It's worked, at least for that error.  I've had several more of the same
sort, and one or two blockages since.  I've got stuck rebuilding xfce,
but that will have to wait till tomorrow.

It really does mean exactly what it says. Look at it again:

(dependency required by "sys-fs/cryptsetup-1.1.3-r3[-dynamic]" [ebuild])

It's saying there is a dependency, and the package that requires it is 
cryptsetup. Read it like this::

(dependency, required by ..... )

OK, I think I've got it now.  What was confusing me is that in ordinary
English, a "dependency" is a relationship, but in emerge it's a thing.
Thanks for the help, it's appreciated.

I'm not the best at figuring out portages puke either but I get the same 
if I try to install cryptsetup as shown here:

root@fireball / # emerge -vp cryptsetup

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

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy 
"dev-libs/libgcrypt[static-libs]".
!!! One of the following packages is required to complete your request:
- dev-libs/libgcrypt-1.4.6 (Change USE: +static-libs)
(dependency required by "sys-fs/cryptsetup-1.1.3-r3[-dynamic]" [ebuild])
(dependency required by "cryptsetup" [argument])
root@fireball / #

I would try to figure out what is pulling in cryptsetup and see if you 
can adjust your USE flags.  Adding the -t option may help on that.

One thing I have learned, read portages error message backwards.  It 
starts spitting it up at one point then works its way back.  Most of the 
time, you don't need the waaaaay back part.

By the way, I don't have static-libs enabled here either.

Hope that helps.

You should: nano /etc/make.conf

and add the flag: static-libs

USE="static-libs"

Then try again: emerge -uDvaN world

I would do

  USE="static-libs" emerge -Dup libgcrypt

& if that works, add the flag to  /etc/portage/package.use .

That will also set the USE flag for any other packages in libgcrypt's
dependency tree. Additionally, it will add libgcrypt to @world, which
is also unwanted.

mkdir -p /etc/portage/package.use
echo dev-libs/libgcrypt static-libs

I might add, he has the -p option in there.  It's not going to *do* 
anything but show if it will work or not.  Then a person can adjust the 
USE settings the correct way and remove the -p option or add -a.  I do 
the later myself.

I hadn't noticed the -p, but what will it show? It certainly won't show
whether setting that USE flag globally will correct the error message, as
the pretend emerge is for one package, and not the one causing the
problem. You'd need to emerge -p world for that, and setting USE flags on
the command line for that is even worse.

I agree that setting about anything on the command line is a bad idea.  
However, it is just to test it to see what, if anything, it changes.

But it doesn't tell you if setting the flag solves the problem, because
it doesn't attempt to emerge the package that failed. As a test it fails.

sudo emerge -av flaggie

A package-specific useflag editor is _very_ useful for these kinds of problems.
Relevant files are /etc/portage/package.use, where cat/pkg use1 ...
useN does USE: +...
and /etc/portage/package.use.mask, where cat/pkg use1 ... useN does USE: -...
