[cfe-dev] Problem parsing a simple C++ file.

[Manuel Klimek]

Instead of using CompilerInstance yourself, you could try writing either a
clang plugin or use libtooling (see
http://clang.llvm.org/docs/Tooling.htmlfor when to use what).

If you cannot do that for some reason, you can take a look at:
http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Tooling/Tooling.cpp?view=markup
for a working (rather minimal) example on how to set up a CompilerInstance.

Cheers,
/Manuel
