Building from source
You can download and run this build script.
Alternatively, you can build manually. Start by checking out llvm, clang and cling:
Then use CMake to configure & build cling:
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)|
