Facebook Clang Plugins

This folder contains the Infer frontend plugin to the clang compiler used to process the syntax of source files and export AST information to the Infer frontend.

Structure of the repository

  • libtooling : frontend plugins (currently a clang-to-json AST exporter),

  • clang-ocaml : OCaml libraries to process the JSON output of frontend plugins,

Quick start

The plugin requires recent version of the clang compiler, re-compiled from source.

To compile and use the required version of clang, please run ./clang/setup.sh.

Caveat:

  • Because of the nature of C++, clang and the plugins need to be compiled with the exact same C++ libraries.
  • Also, the default stripping command of clang in release mode breaks plugins.

Once the target compiler is installed, make test should run the unit tests.

OCaml users may also run:

make -C clang-ocaml test  #requires proper ocaml libraries, see included clang-ocaml/README

Additional configuration options are available in Makefile.config.
