### Building from Source with Cling Packaging Tool ### Building from Source
Cling's tree has a user-friendly, command-line utility written in Python called
Cling Packaging Tool (CPT) which can build Cling from source and generate
installer bundles for a wide range of platforms. CPT requires Python 3 or
later.
If you have Cling's source cloned locally, you can find the tool in
`tools/packaging` directory. Alternatively, you can download the script
manually, or by using `wget`:
```sh ```sh
wget https://raw.githubusercontent.com/root-project/cling/master/tools/packaging/cpt.py git clone https://github.com/root-project/llvm-project.git
chmod +x cpt.py cd llvm-project
./cpt.py --check-requirements && ./cpt.py --create-dev-env Debug --with-workdir=./cling-build/ git checkout cling-latest
cd ../
git clone <cling>
mkdir cling-build && cd cling-build
cmake -DLLVM_EXTERNAL_PROJECTS=cling -DLLVM_EXTERNAL_CLING_SOURCE_DIR=../cling/ -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_TARGETS_TO_BUILD="host;nvptx" ../llvm-project/llvm
``` ```
Full documentation of CPT can be found in [tools/packaging](tools/packaging).
