list of all header files included by a C file

Question

I am trying to \"arm\" compile a C file,it includes lot of header files recursively..i am trying to find the list of these header files..is there a easier way to find the li

Answer 1

You can use the GCC C preprocessor with it's option to dump a list of headers recursively included:

cpp -M

That will show you all headers included.

You will probably need to give it the roots of all include directories used in your regular build. Run it iteratively, adding more include paths until the errors stop.

The full form of this command in this usage is:

cpp -M [-I include_directory *] path_to_c_file.c
