Question

I recently added -pedantic and -pedantic-errors to my make GCC compile options to help clean up my cross-platform code. All was fine until it found errors in external-included header files. Is there a way to turn off this error checking in external header files, i.e.:

Keep checking for files included like this:

#include "myheader.h" 

Stop checking for include files like this:

#include <externalheader.h> 

Here are the errors I am getting:

Answer 1

You could fix the headers and submit a patch to FFmpeg; compatibility with -pedantic is a worthy goal, so I’m sure they’d consider it, especially if it just involved removing trailing commas and suchlike.
