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-llvm13 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
cling patches?
Cling needs a couple of patches on top of clang (but can work with an original build of llvm). These are the commits that above build instructions correspond to - which is mostly interesting to package maintainers:
cling release | upstream llvm and clang | cling-patches on clang | |||
---|---|---|---|---|---|
0.5 | 5.0 release series | 287240.. 27d2d5 (aka cling-patches-rrelease_50) | 0.7 | 9.0 release series |
