[LLVMdev] Purpose of LLVM_ENABLE_LIBCXX and LLVM_ENABLE_LIBCXXABI

[Schlottke-Lakemper, Michael]

Hi Martell,

I am wondering about the meaning of the cmake flags LLVM_ENABLE_LIBCXX and LLVM_ENABLE_LIBCXXABI. Are they used to indicate that if the C/C++ compiler for building LLVM is clang, and if this clang has support for libc++ with libc++Abi, that both lib++ and libc++abi should be used (instead of linking to the default, which at least on Linux is libstdc++)?

Yes that is actually what they are used for.

Thank you for the confirmation. I saw the help text in CMakeLists.txt but was not sure whether it refers to the build process itself or the behavior of the resulting compiler.

Michael
