Re: Missing files from libclang-common on ports

Hi John, all,

I've built LLVM HEAD using:

cmake -DLLVM_ENABLE_PROJECTS="clang;compiler-rt" -DLLVM_TARGETS_TO_BUILD="X86;PowerPC" -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" ../llvm

And it does seem that there is no libclang_rt.asan-powerpc.a being generated. The clang docs are a bit vague, though they do state that "most sanitizers are only supported on Linux X86-64". So it seems that indeed it's not supported.

The ASAN docs did suggest support: https://github.com/google/sanitizers/wiki/AddressSanitizer

For now this seems to solve the confusion though.

Cheers,

Thom

Looking at the build log, it seems that libclang_rt.asan-powerpc.a is not being built on powerpc:

I'm not sure why. Have you tried checking out LLVM from git and see if it gets build there?

Just use the regular Debian bug tracker:
