Getting started with clang

Clang Frontend
1

Hello everyone,
I am quite impressed about the clang project but I have problems in getting started with it. Actually I want to use clang as a component, thus embed the parser, static analyzer and rewriting mechanism into another program.

I can't find any examples about that, at the moment I can run the clang parser from the command line but it's not what I really need! :slight_smile: I don't even know which are the header files I should include in my project. Could you please give me a pointer to something (even an header file should be great) where I can start? How can I build the AST starting from a source file?

thanks in advance for the help!
best regards,

Simone Pellegrini

After compiling you will have clang's include files in
llvm/tools/clang/include
and llvm's include files in
llvm/include

To begin see what the clang program itself does checking the files in the
folder llvm/toots/clang/Driver .

We can give some other hints if you tell us what you need to do.

Hi Simone,

I would suggest you look at "ASTConsumers" in the Driver subproject and "ParseAST" in lib/Sema.
