gcc-objc++-4.8.2.mips64el-linux fails to be built because of:

building of `/gnu/store/avdn8phqm44v33p6k42pipybcgjs92mb-gcc-objc++-4.8.2.drv' timed out after 72000 seconds
@ build-failed /gnu/store/avdn8phqm44v33p6k42pipybcgjs92mb-gcc-objc++-4.8.2.drv - timeout

I think it simply takes more than 12 hours...

Do you think there might be a way of compiling all gcc languages in one go
instead of in several packages? Maybe enable all languages in gcc? Or would
this create too big a gcc package? Also, maybe we could drop one of the three
gcc versions.

And finally, why are there two gcc-4.8.2 packages, and where are they actually?
$ guix package -A gcc
gcc     4.7.3   out     gnu/packages/gcc.scm:95:4
gcc     4.8.2   out     gnu/packages/gcc.scm:95:4
gcc     4.9.0   out     gnu/packages/gcc.scm:95:4
gcc     4.8.2   out     gnu/packages/gcc.scm:95:4

Is there a way of printing not the line 95 in which the base gcc package is
defined from which all others inherit, but the line where the actual package
is defined?

Ahah.  :-)

That would be too big.  Plus, when you say “all”, do you really mean Ada
and Java for instance?  These make things definitely bigger.

The default package does C and C++.  We could imagine another one that
would in addition to Objective-C and FORTRAN, yes.  That would save
build time, at the expense of being somewhat confusing to the user IMO.

One of the GCC 4.8.2 is ‘gcc-final’ in base.scm.

Yes, good idea.

I’ve just committed this patch:

Okay.

Sorry, here I meant the version numbers 4.7.3, 4.8.2 and 4.9.0. Maybe we could
drop 4.7.0?

> One of the GCC 4.8.2 is ‘gcc-final’ in base.scm.

So this is the one that is used for compiling all our packages? Could we
then not drop the gcc-4.8.2 from gcc.scm and let the user install gcc-final?
Or otherwise, give it a different NAME?

Hm, I meant in all generality for all packages that are inherited. Would
this be easily possible?

Eventually yes, but for now I think it may still be useful to have 4.7
around (for instance, as a developer it’s sometimes useful to test with
older compilers.)

Yes.

It’s been discussed several times, but there’s no satisfactory solution
so far.  Changing the name seems like a bad idea, because it’s really
gcc.  Making either gcc-final or gcc-4.8 private isn’t an option because
they’re referred from elsewhere.

Maybe package objects should have an extra property that says whether
they should be hidden?

Hmm, define-record-type* could be augmented with an inheritable? flag,
and the ‘location’ field would be marked as non-inheritable, something
like that.

Sorry for my forgetfulness. So the references to gcc-4.8 could not be replaced
by references to gcc-final? Notice, for instance, that gcc-toolchain-4.8 does
not use gcc-4.8, but gcc-final already.

No.  It’s a bit tricky but the idea is: gcc-4.8 is the “abstract” recipe
for GCC, whereas gcc-final is a specialized recipe for use in the
bootstrap process.

The abstract recipe has useful properties:

  • it is a “normal”, self-contained package recipe, and thus easier to
    grasp;

  • it can be cross-compiled (whereas gcc-final cannot, because it is
    anchored in the bootstrap dependency DAG);

  • it can easily be derived (for gfortran, etc.);

  • it remains valid even when the default GCC version changes.

So we need that abstract gcc-4.8.

At the same time, for native compilation, we only ever want to use
gcc-final, because gcc-4.8 is just the same compiler built once more
with itself.

So ideally, ‘guix package’ would magically ignore the abstract gcc-4.8
(and coreutils, grep, etc.) and favor their -final variant.

I hope I’m being clear, but I’m not sure.  ;-)
