Subject: bug#49600: [core-updates] gcc-11 fails to cross-compile from x86_64-linux
Date: Fri, 16 Jul 2021 21:04:24 -0300 [thread overview]
Message-ID: <5098239.b5oAXHIL8O@popigai> (raw)
Hello,
On core-updates (at least as of commit 8456581375cf), the gcc package fails
to cross-compile. This can be seen in the following CI jobs:
• https://ci.guix.gnu.org/build/667365/details
gcc-11.1.0, arm-linux-gnueabihf.gcc.x86_64-linux
• https://ci.guix.gnu.org/build/667394/details
gcc-11.1.0, aarch64-linux-gnu.gcc.x86_64-linux
• https://ci.guix.gnu.org/build/667452/details
gcc-11.1.0, powerpc64le-linux-gnu.gcc.x86_64-linux
• https://ci.guix.gnu.org/build/667481/details
gcc-11.1.0, riscv64-linux-gnu.gcc.x86_64-linux
• https://ci.guix.gnu.org/build/667336/details
gcc-11.1.0, mips64el-linux-gnu.gcc.x86_64-linux
• https://ci.guix.gnu.org/build/667423/details
gcc-11.1.0, powerpc-linux-gnu.gcc.x86_64-linux
They all fail with a similar error:

In addition to that, arm-linux-gnueabihf.gcc.x86_64-linux has the following
error which doesn’t appear on the other arches:
no include path in which to search for stdc-predef.h
As a side note, gcc-11.1.0 also fails to build on
i586-pc-gnu.gcc.x86_64-linux¹, but with a very different error message,
so it appears to be an unrelated problem.
gcc-8.5.0 also fails to cross-compile on several arches, but with a
different error message as well, so it also appears to be a separate
problem.
