Hi all,
I’m new to libclang, recently I wrote a program for testing parsing, basically it output the ast to stdout. But when I run it over some source file, there are some statements missing? I can’t figure out what happened. The question was originally posted at stackoverflow, but no reply until now 
Can any one give me some hints? Thanks very much.

Sincerely Yours,

The problem is that parsing is failing due to missing a stddef.h, so
the lines that fail to parse aren't in the AST. I can get it to work
on my system by running it like this:
./parse_ast -I/usr/local/bin/../lib/clang/3.3/include tt.c
There is some info on this at
http://clang.llvm.org/docs/LibTooling.html#builtin-includes. This
problem comes up a lot, so you could also search the list archive for
stddef.h for more discussion of it.
you might want to add some error handling, see page 15:
