            Bug ID: 755864
           Summary: C++ Linker problem for gst_app_src_push_sample
    Classification: Platform
           Product: GStreamer
           Version: 1.6.0
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: kjrusscher at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Please describe the problem:
GCC C++ Compliler can create the .0-files for .cpp-files with the function
gst_app_src_push_sample, which is in gst/app/gstappsrc.h. But the GCC C++
Linker returns an 'undefined reference' for gst_app_src_push_sample. The linker
has no problem finding other functions that are in gst/app/gstappsrc.h, like
the function gst_app_src_push_buffer.
The sample file ./gst-plugins-base/tests/examples/app/appsink-src2.c, which
also contains gst_app_src_push_sample is build completely when building
gstreamer-1.6.0.

Steps to reproduce:
1. copy the file ./gst-plugins-base/tests/examples/app/appsink-src2.c to
appsink-src2.cpp
2. make the file with the needed include path's and libraries

Results:
GCC C++ Linker returns: undefined reference to 'gst_app_src_push_sample'


Does this happen every time?
Yes.

Linux 3.16.0-50-generic Ubuntu 14.04.1 x86_64
