Description Bob Dröge 2023-01-13 09:38:32 UTC

I'm trying to do a Prefix bootstrap on a Starfive VisionFive 2 (RISC-V), and during the 2nd stage the build of sys-devel/gcc-12.2.1_p20221231 fails due to:

In file included from /nvme/gentoo/tmp/var/tmp/portage/sys-devel/gcc-12.2.1_p20221231/work/gcc-12-20221231/libgcc/../gcc/tsystem.h:87,
                 from /nvme/gentoo/tmp/var/tmp/portage/sys-devel/gcc-12.2.1_p20221231/work/gcc-12-20221231/libgcc/libgcc2.c:27:
/usr/include/stdio.h:27:10: fatal error: bits/libc-header-start.h: No such file or directory
   27 | #include <bits/libc-header-start.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

The file is available (on the host, at least; I don't know if it should be somewhere in the Prefix build dir?) in:
/usr/include/riscv64-linux-gnu/bits/libc-header-start.h


Reproducible: Always
