Reporting unnecessary inclusion of header files.

Reporting unnecessary inclusion of header files.

Hi All,

 I am looking for someone help on header file inclusion in C/CPP code. Can
gcc help me to report the unnecessary inclusion of header files in my
project? If not what are the other ways I can do it?

Thanks,
-Rajeev

No, gcc can't help with this. But there's a clang-based tool for it:

Thanks Jonathan. I have C++ code as well in my project, it looks like iwyu
is compatible with llvm+clang compiler, any idea it will work with gcc as
well?

Thanks,

I'm not sure what you mean. As I said, it is a clang-based tool. It works
with both C and C++.

No, it won't work with GCC. It uses clang libraries.
