3 years ago Thanks - that makes things a little clearer. It looks like maybe the build of nativesdk-clang is trying to use gold but not finding it and reverting to the system gold. Where should the yocto-built glibc and binutils get its copy of gold?

3 years ago It would appear that removing the -fuse-ld=gold in clang_git.bb "fixes" this problem for me, though it seems unlikely that it's the best solution.

3 years ago that would fix it since ld.bfd is already modified to address relocatable interp section, but we also had this done for gold recently so it seems this might not be working in gold then.

3 years ago I have tried building Clang in SDK for riscv64 and 0001-binutils-crosssdk-Generate-relocatable-SDKs.patch didn't help (using master of meta-clang) and a month old oe-core/meta-oe.

3 years ago I think it was a workaround to avoid ld/gold relocation not working I think it could be reverted can you paste errror message you see ?

Not sure what's the status of ld.lld (I think it might not be on the level as ld.bfd yet). Sticking to ld.bfd might be the best option right now for riscv, but again I don't follow ld.lld development closely.

3 years ago ok lets stick to ld.bfd

I could see the below patches are present in my repository. But still I could see relocation errors (may be these are irrelevant for rust pkg). meta/recipes-devtools/binutils/binutils/0001-binutils-crosssdk-Generate-relocatable-SDKs.patch 0005-nativesdk-glibc-Raise-the-size-of-arrays-containing-.patch
Also, in 'meta/recipe-devtools/rust/' I couldn't find and LDFLAGS/Linker info to implement similar patch. Anyway, I tried to modify the _scripts/relocationsdk.py (_changeinterpreter function) to increase the path size, but the installed SDK binaries are corrupted and not working.
Any clue where I should modify the size of .interp section to increase the sdk relocation path size and fix this issue for rust tools?
