[cfe-dev] Building clang 5 (for coroutines)

I'm not too familiar with building with the monorepo, but does adding
libcxxabi to LLVM_ENABLE_PROJECTS change anything? The missing references are
to c++abi functions.

    I've been doing some tries. I thought I could just run cmake with 
    different projects listed and it would re-write the build files. Turns 
    out it doesn't work like that. So, I've done some builds like this:
    
    CC=gcc CXX=g++ cmake ../svn/llvm -DLLVM_ENABLE_PROJECTS="llvm" 
    -DCMAKE_BUILD_TYPE=Release
    
    CC=gcc CXX=g++ cmake ../svn/llvm -DLLVM_ENABLE_PROJECTS="llvm;clang" 
    -DCMAKE_BUILD_TYPE=Release
    
    These first two work, but this one:
    
    CC=gcc CXX=g++ cmake ../svn/llvm 
    -DLLVM_ENABLE_PROJECTS="llvm;clang;libcxx" -DCMAKE_BUILD_TYPE=Release
    
    This one fails, so the problem is in building the library. The errors 
    look to me like things that are in the library itself are missing. I've 
    included the full list below this time, and you can see, way down at the 
    bottom, the errors are in linking libc++.so.1.0
