After spending a lot of time trying to figure out how to use libclang in my C++ project in NetBeans, here’s the recipe that did it:

1) Install LLVM and Clang sources.

2) Build LLVM. This took about 3-4 hrs.

3) Include the library generated from clang:

- Go to Project Properties > Build > Linker.

- Add the path to libclang.so to the Libraries path using “Add Library File...” option.

- In case code editor is giving trouble, add the path to /include in the sources using Tools > Options > C/C++ > C++ Compiler > Add > <path to /include folder in llvm src>
