See also "/tmp/qtc-cmake-yMRXIp/CMakeFiles/CMakeOutput.log". *** cmake process exited with exit code 1. Even when I remove the >=1.4 part of pkg_check.. I'm still getting the same error. I am lost, I really have no clue here. I've tried reading the information that's out there, but it does not make sense to me. I don't know if PkgConfig is just a place holder for an actual name of some package, if that is the actual value that needs to be passed in. I thought I had gstreamer-1.0 installed on my machine. Maybe I don't. Here is what I get when I search for gstreamer in Synaptic Package Manager and filter on things that are installed. <img alt="what is installed" src="cid:part1.70B05F00.1DFEFB0B@hotmail.com" height="750" width="888"> All I'm trying to do here is follow along with the gstreamer documentation so that I can ramp up on gstreamer and use it. Are there examples out there that are very explicit in how to: 1) figure out what version of gstreamer you have installed 2) shows you how to use CMake to compile against an app that is using gstreamer? Rather that is manually creating a cmake file or using the pkg-config options. 3) Lists out exactly what values you need in your cmake file? Thanks for additional assistance.

The library check is done by this line: pkg_check_modules(GST REQUIRED gstreamer-1.0>=1.4 gstreamer-sdp-1.0>=1.4 gstreamer-video-1.0>=1.4 gstreamer-app-1.0>=1.4) The list can be adjusted, the required version too.
