Hi all,

I believe there's been a recent regression w/re MAKE-GCC-TOOLCHAIN. I'm unable
to guix build the following minimal reproducer:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages commencement)
             (gnu packages gcc)
             (gnu packages base))

(make-gcc-toolchain gcc glibc-2.27)
--8<---------------cut here---------------end--------------->8---

My guix describe output:
Generation 33   Oct 22 2019 15:07:03    (current)
  guix f5d6c88
    repository URL: https://git.savannah.gnu.org/git/guix.git
    commit: f5d6c88d0f5e1556295c1a19c46ddfcb7a23107f

The build failure logs can be found here:

So we see tons of things like:

The ‘configure’ phase shows that ‘strsignal’ and ‘sbrk’ were not quite
found, but this is confusing:

--8<---------------cut here---------------start------------->8---
checking for strsignal... no
checking for pstat_getstatic... yes
checking for sysconf... no

checking for wait3... no
checking for strerror... yes
checking for wait4... yes

[…]
checking whether sbrk is declared... yes
--8<---------------cut here---------------end--------------->8---

Does it work with ‘glibc-2.28’?

We’re not building any such toolchain in CI but we probably should…

Hi Ludo’,

> Does it work with ‘glibc-2.28’?

Curiously... glibc-2.28 also doesn't work:

I think so too, happy to contribute a patch for the CI after we figure this out.

Hi all,

Looking closer at the code, the regression seems to be in MAKE-GCC-LIBC in (gnu
packages base), rather than in MAKE-GCC-TOOLCHAIN.

New minimal reproducer:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages commencement)
             (gnu packages gcc)
             (gnu packages base))

(make-gcc-libc gcc glibc-2.28)
--8<---------------cut here---------------end--------------->8---

I tried this today as of commit 49d19b35cebd749510b7dddd773d76a3a96d1358
and it seems to build.

Are you still experiencing this issue?
