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

I think the problem comes from this bug in GCC: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106271 Actually, I see that the file: gentoo/tmp/var/tmp/portage/sys-devel/gcc-13.2.1_p20240113-r1/work/gcc-13-20240113/gcc/config/riscv/t-linux looks like: # Only XLEN and ABI affect Linux multilib dir names, e.g. /lib32/ilp32d/ MULTILIB_DIRNAMES := $(patsubst rv32%,lib32,$(patsubst rv64%,lib64,$(MULTILIB_DIRNAMES))) MULTILIB_OSDIRNAMES := $(patsubst lib%,../lib%,$(MULTILIB_DIRNAMES)) So, probably applying this patch: https://gcc.gnu.org/git/?p=gcc.git;a=blobdiff;f=gcc/config/riscv/t-linux;h=a6f64f88d25c989159207cbef19778b703c95797;hp=216d2776a183d13ade76642b73b9bf04b0c4694e;hb=47f95bc4be4eb14730ab3eaaaf8f6e71fda47690;hpb=0698c9fddfc5a41dd7f233928b7a486cb044fea3 would solve the problem.
Do we know if applying this patch actually makes the compilation go through?
Happy to add it to patchset etc if it's confirmed to work.
(In reply to Fabian Groffen from comment #4) > Do we know if applying this patch actually makes the compilation go through? Yes, I added the line manually after the bootstrap script downloads and decompress gcc and the compilation definitely goes through this point.

OK, will do. Thanks!
