[cfe-dev] How to build a clang-tool out of the build tree?

[Laurent Thévenoux via cfe-dev]

Hi,

I’m trying to develop a clang-tool, following such kind of tutorial : https://clang.llvm.org/docs/LibASTMatchersTutorial.html <https://clang.llvm.org/docs/LibASTMatchersTutorial.html>.

I’m using GitHub with Travis-CI and I can’t build clang/llvm on Travis because of the free-plan constraints. I’m wondering if it is possible to build such a tool without having to build clang/llvm, i.e., is there a way to simply install clang (from any package manager) with its LibTooling and LibASTMatchers, to which I could link my tool with?

Regards,
Laurent
