Cross-compiling bootstrap tarballs fails on core-updates

Cross-compiling bootstrap tarballs fails on core-updates

Hello!

Building 'bootstrap-tarballs' for other architectures fails on
core-updates.  Here is the comparison to the previous core-updates
evaluation in December:

https://hydra.gnu.org/eval/109945?compare=109875#tabs-now-fail

There seems to be a couple of different problems here.

'patch' fails to build due to a conflicting declaration of
'__mktime_internal':

--8<---------------cut here---------------start------------->8---
  CCLD     patch
/gnu/store/9v09kidvqykyk2kh26q297di3lkjc8vy-glibc-cross-arm-linux-gnueabihf-2.27-static/lib/libc.a(mktime.o): In function `__mktime_internal':

collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:1230: patch] Error 1
--8<---------------cut here---------------end--------------->8---

Note that there is a warning about __mktime_internal earlier:

--8<---------------cut here---------------start------------->8---

timegm.c: In function 'rpl_timegm':

timegm.c:39:10: note: in expansion of macro '__mktime_internal'
   return __mktime_internal (tmp, __gmtime_r, &gmtime_offset);
--8<---------------cut here---------------end--------------->8---

Then we have 'ncurses' failing in the install phase with:

--8<---------------cut here---------------start------------->8---
make[1]: Entering directory '/tmp/guix-build-ncurses-6.1.drv-0/ncurses-6.1/progs'

make[1]: *** [Makefile:201: install.progs] Error 1
--8<---------------cut here---------------end--------------->8---

The error message here is odd: /gnu/store/.../bin/tic is not installed
yet at this point.  The built binary looks fine however.  Quoth `file`:

/dev/shm/guix-build-ncurses-6.1.drv-0/ncurses-6.1/progs/tic: ELF 32-bit LSB executable, ARM, EABI5
version 1 (SYSV), dynamically linked, interpreter /gnu/store/jiw5wrjvcipfxnpl56572x4bf6gdvypf-glibc-cross-arm-linux-gnueabihf-2.27/lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, with debug_info, not stripped

I'm not sure why these failures happen only when cross-compiling.  The
respective native builds are okay.  Thoughts?

For those following along at home, you can reproduce these failures by
checking out the core-updates branch, and then run:

./pre-inst-env guix build --target=arm-linux-gnueabihf bootstrap-tarballs

(or any other target triplet, they fail in the same way)

Could this be related to the following bug report?

This is fixed by these commits:

  c77835db0 * gnu: tar: Work around a cross-compilation issue.
  b0ff3606b * gnu: ncurses: Do not use "install -s" when cross-compiling.
  d3878d3d5 * gnu: patch: Work around a cross-compilation issue.

Thanks for the heads-up!
