libclang

Bindings / wrapper API for libclang in the D programming language.

Build Instructions

Note: for a reproducible and cross-platform build environment, you can run setup-cpp with --llvm=11.0.0. This will set up LLVM 11.0.0 and the proper environment variables.

Windows

Install LLVM into C:\Program Files\LLVM\, making sure to tick the "Add LLVM to the system PATH for all users" option.

If libclang.lib was not found, put the lib folder of the llvm directory on the PATH.

Linux

If libclang.so was not found, link it using the following command (adjust the installation path and the llvm version):

sudo ln -s path_to_llvm/lib/libclang-12.so.1 /lib/x86_64-linux-gnu/libclang.so

MacOS

If using an external LLVM installation, add these to your ~/.bash_profile

LLVM_PATH="/usr/local/opt/llvm/" # or any other path
LLVM_VERSION="11.0.0"
export PATH="$LLVM_PATH:$PATH"
export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)
export LD_LIBRARY_PATH="$LLVM_PATH/lib/:$LD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH="$LLVM_PATH/lib/:$DYLD_LIBRARY_PATH"
export CPATH="$LLVM_PATH/lib/clang/$LLVM_VERSION/include/"
export LDFLAGS="-L$LLVM_PATH/lib"
export CPPFLAGS="-I$LLVM_PATH/include"
export CC="$LLVM_PATH/bin/clang"
export CXX="$LLVM_PATH/bin/clang++"

(adjust the clang version and the external llvm installation path.)

Then run source ~/.bash_profile

If libclang.dylib was not found, link it using the following command (adjust the installation path):

ln -s path_to_llvm/lib/libclang.dylib /usr/local/opt/llvm/lib/libclang.dylib
