Description Peter Waller 2019-01-08 07:02:07 PST 
LLVM was built like so:

Revision r348444

git clone --depth=1 https://github.com/llvm-mirror/llvm
cd llvm
mkdir build
cd build
cmake \
    -DCMAKE_BUILD_TYPE=MinSizeRel \
    -DCMAKE_INSTALL_PREFIX=$PWD/install \
    -DLLVM_INCLUDE_EXAMPLES=OFF \
    -DLLVM_ENABLE_ASSERTIONS=ON \
    -DLLVM_BUILD_LLVM_DYLIB=ON \
    -DLLVM_TARGETS_TO_BUILD='' \
    -DCMAKE_CXX_FLAGS='-march=native' \
    -DCMAKE_C_FLAGS='-march=native' \
    -DLLVM_ENABLE_PROJECTS='clang' \
    ..
make install


This installs LLVM to $DIR/llvm/build/install.

If I then run `$DIR/llvm/build/install/llvm-config --link-shared` I get: `llvm-config: error: libLLVM-7.dylib is missing`.

I expected it to report `$DIR/llvm/build/install/lib/libLLVM.dylib`, which does exist.

Judging by llvm-config, this can't work, since the code hard-codes a `-` separator:
