Compile QT app in Ubuntu

[Mikl]

Hello,

I have this errors when compiling c++ QT project in Ubuntu 16.

and 217 more of the same type

What is wrong?
How to fix it?

------------------------------------
that's how i include gstreamer headers:
extern "C" {
//gstreamer library
#include <gst/gst.h>
#include <gst/app/gstappsink.h>
#include "gst/app/gstappsrc.h"
}

------------------------------------

Do you need something else?
