YouCompleteMe doesn't show errors when non standard header is included

Question

When I try include gst.h YCM start innoring all error

For example:

#include <math.h>
//#include <gst/gst.h>

main (){ //ycm show error here
int a=0;
int b    //and here
}

but

#include <math.h>
#include <gst/gst.h>

main (){ //ycm don't show error here
int a=0;
int b    //and here
}

path to gst.h included to .ycm_extra_conf.py . What i miss?

Answer 1

:YcmDiags show all warning and error YCM messages. You must include all nested headers and then YCM parse your code right. Also you must install clang lib correct for C/C++ language.
