Problems building libc++ with clang for memory sanitizer #97281

Open Desperado17 opened 4 days ago

Desperado17 commented 4 days ago

I try to build an instrumented libc++ to avoid false positives with memorysanitizer according to this manual: https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo

Clang 14, Ubuntu 22.04, x64

After some modifications I came up with an updated command but it yielded errors:

cmake -G Ninja -S runtimes -B msan_out  \
    -DCMAKE_BUILD_TYPE=Release \
    -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind" \
    -DCMAKE_C_COMPILER=clang \
    -DCMAKE_CXX_COMPILER=clang++ \
    -DLLVM_USE_SANITIZER=MemoryWithOrigins

ninja -C msan_out cxx cxxabi

ninja -C msan_out cxx cxxabi
ninja: Entering directory `msan_out'

Any ideas what I can do? Regards!

philnik777 commented 4 days ago

How about you don't ignore warning: "Libc++ only supports Clang 17 and later" [-W#warnings]? Did you just miss it? If that's the case, maybe we should upgrade this to an error or even fatal by default.

Desperado17 commented 4 days ago

Ah I see. Too much output I guess.

Strangely, I have a libc++ for my clang-14 installed on my Ubuntu 22. How could this have been compiled? Even the llvmorg-14.0.0 branch prints this same warning for me with clang 17.

EugeneZelenko commented 3 days ago

Could you please try 18 or main branch?

Desperado17 commented 3 days ago

I just now had success with 17. Is there a reason for going to 18?
