While doing a make on the recently checkout version: I got the following errors: [ 68%] Built target dd [ 68%] Built target compiler-rt-headers [ 68%] Building C object projects/compiler-rt/lib/builtins/CMakeFiles/clang_rt.builtins-x86_64.dir/x86_64/floatdidf.c.o In file included from /home/tthtlc/llvm/llvm/projects/compiler-rt/lib/builtins/x86_64/floatdidf.c:9:0:

Has the autconf build an option similar to LLVM_ENABLE_PEDANTIC ? If yes, what's its default?

Yes that

Hi, 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++)? If not, what is the canonical way of

That seems to work (see below). $ cd
