Subject: gcc -m32 can't find stubs-32.h  
Date: Sat, 7 Jul 2018 20:55:44 +0200 (CEST)

I tried to run gcc to compile a simple c program which fails:

gcc -m32 -o m32test m32test.c
In file included from /home/user1/.guix-profile/include/features.h:388,
                 from /home/user1/.guix-profile/include/stdio.h:27,
                 from m32test.c:2:
/home/user1/.guix-profile/include/gnu/stubs.h:7:11: fatal error: 
gnu/stubs-32.h: No such file or directory
 # include <gnu/stubs-32.h>
           ^~~~~~~~~~~~~~~~
compilation terminated.

with -m64 it compiles correctly. In ~/.guix-profile/include/gnu/ I have 
the files:

libc-version.h
lib-names-64.h
lib-names.h
stubs-64.h
stubs.h

Expected result is that it silently works.

Are you using the “gcc-toolchain” package?

I reproduce that bug with gcc-toolchain.

If you’re trying to compile for i686, should you not be using the i686
variant of gcc-toolchain?  You can build it with

    guix build --system=i686-linux gcc-toolchain

(I don’t really know much about this, but we don’t build GCC with
multilib support.)

How would you install that variant?

This option is in the gcc manual that we package, so I think it should
be supported.

Currently you’d have to do:

  guix package -i `guix build -s i686-linux gcc-toolchain`

which is not ideal.

Yeah.  The problem is that currently we don’t build glibc with multilib
support.  Something for the next ‘core-updates’ cycle if you feel like
working on it!  :-)

I can't work on it and I also don't need it at all.  I'm just confirming
what David says :-)
