[llvm-dev] Linker errors after installing/compiling LLVM/CLANG

[Neil Nelson via llvm-dev]

Joan, For ninja here I would do the following, noting 
https://llvm.org/docs/GettingStarted.html

cd llvm-project

rm -rf build

mkdir build

cd build

Your cmake line might be

cmake -G Ninja -DLLVM_ENABLE_PROJECTS=clang 
-DCMAKE_INSTALL_PREFIX=/Users/joan/LLVM-9/install 
-DLLVM_OPTIMIZED_TABLEGEN=On ../llvm

I would use

cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_USE_LINKER=lld 
-DCMAKE_BUILD_TYPE="Release" 
-DCMAKE_INSTALL_PREFIX=/Users/joan/LLVM-9/install ../llvm

ninja

ninja install

I am not familiar with Xcode. But if the above works you might be in a 
position to use the executables and libraries in the just installed 
directory in an Xcode project.
