I am looking at making use of the Clang's AST for my C code and do some analysis over the AST. Some pointers on where to start, how to obtain the Clang's AST, tutorials or anything in this regard will be of great help!!!

I have been trying to find some and I got this link which was created 2 years back. But for some reason, it is not working for me. The sample code, in the tutorial, gives me too many errors. So I am not sure, if I build the code properly or some thing is wrong with the tutorial. But I would be happy to start from some other page as well.

Start with the tutorial linked by sharth. Then go through Clang's Doxygen. Start with SemaConsumer.

Read a lot of source code. Clang is a moving target. If you are writing tools based on clang, then you need to recognize that clang is adding and fixing features daily, so you should be prepared to read a lot of code!
