clang: ToolChains/Gnu.cpp: search also in lib32 #851

Closed shr-project closed 1 year ago

shr-project commented 1 year ago

Draft, because this is still just part of the fix, now the GCC installation is found, but the default libdir still doesn't allow to find Scrt1.o or libgcc_s.so.

I've tried to add:

-DLLVM_LIBDIR_SUFFIX=${@d.getVar('BASELIB').replace('lib', '')}

because of:

clang/CMakeLists.txt:set(CLANG_LIBDIR_SUFFIX "${LLVM_LIBDIR_SUFFIX}")
clang/CMakeLists.txt:set(CLANG_INSTALL_LIBDIR_BASENAME "lib${CLANG_LIBDIR_SUFFIX}")

which seems to be added to default search paths in most places.

I've added it to native build as well (it was only in target build - just to verify, because we don't want to have different clang-native for different MACHINEs with different BASELIB (lowercase baselib is set to "lib" in native.bbclass).

But that also doesn't work well:

Will keep it in my branch for a bit longer to test full image build and also build with arm and aarch64 without multilib to see if there are some unexpected side-effects.

lgtm. Can you also port them to clang-17 which is in yoe/mut branch releasing in a weeks time

I've checked that the issue is still reproducible with clang-17: lib32-compiler-rt-17.0.0-r0 do_configure: http://errors.yoctoproject.org/Errors/Details/736239/

lib32-libclc-17.0.0-r0 do_compile: http://errors.yoctoproject.org/Errors/Details/736240/

The same changes work for clang-17, I've cherry-picked them on top of yoe/mut and pushed to jansa/mut (or your yoe/mut branch rebased on top of this PR as jansa/lib32-clang-17)
