Cling Build Instructions

Community support

You can get cling 1.2 from conda-feedstock and there is a user providing an external PPA for debian.

Building from source

Build script

You can download and run this build script.

Manual build

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

git clone -b cling-llvm18 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
