Building from sourcePermalink

Build scriptPermalink

You can download and run this build script.

Manual buildPermalink

Alternatively, you can build manually. Start by checking out llvm, clang and cling:

git clone -b cling-llvm16 https://github.com/root-project/llvm-project.git src
git clone https://github.com/root-project/cling.git

Then use CMake to configure & build cling:

mkdir build
cd build
cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_TOOLS=Off -DLLVM_EXTERNAL_PROJECTS=cling -DLLVM_EXTERNAL_CLING_SOURCE_DIR=../cling -DLLVM_ENABLE_PROJECTS=clang -DLLVM_TARGETS_TO_BUILD="host;NVPTX" src/llvm
cmake --build .
cmake --build . --target install

See also README on the repository.
