Bug 900871 – sys-devel/gcc: fails to build with sys-libs/musl-9999 (musl-1.2.4) because of LFS changes (sanitizer_platform_limits_posix.cpp:182:31: error: invalid application of 'sizeof' to incomplete type '__sanitizer::stat64')

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description immolo 2023-03-11 14:47:35 UTC]

While doing 23.0 profile testing on riscv I've come across an issue where GCC will no longer compile GCC and as Musl 1.2.4 is needed for the 23.0 profiles it might wise for someone else to test and confirm this to see if we need to upstream it or if it's just certain systems that his this as mipsel, aarch64 and amd64 don't seem to hit this issue. 

Reproducible: Always

Steps to Reproduce:
1. enable 23.0 profile default/linux/riscv/23.0/rv64/lp64d/musl1. e
2. add `sys-libs/musl **`` to /etc/portage/package.accept_keywords/musl
3. emerge -va sys-libs/musl
4. emerge -va sys-devel/gcc
Actual Results:  
configure: creating ./config.status
config.status: creating Makefile
config.status: creating libgfortran.spec
config.status: creating config.h
config.status: executing default-1 commands
config.status: executing depfiles commands
config.status: executing libtool commands
config.status: executing gstdint.h commands

make: *** [Makefile:24850: bootstrap-lean] Error 2


emerge --info isn't completely useful as I dropped profiles and downgraded musl to confirm where the errror is for me but still included incase any other information is important.

[Comment 2 Sam James 2023-03-11 14:59:36 UTC]

This is to do with the LFS changes in musl master/1.2.4. It needs to be fixed in libsanitizer.

[Comment 3 Sam James 2023-03-11 15:00:17 UTC]

IIRC this is fixed on the LLVM side already but I haven't confirmed.

[Comment 4 immolo 2023-03-14 03:37:34 UTC]

For completion sake of the report I have selected random GCC version to test this up the latest snapshot of gcc-13 checked out the 12th of march 2023 and all version have the same failure.

[Comment 5 Sam James 2023-03-17 03:58:27 UTC]

We likely need https://github.com/llvm/llvm-project/commit/a5519b99bc73d50f362d6fb306411e9fcb758b53 backported into gcc.
