    Hi, if you tested a vanilla Ubuntu 16.04.1, perhaps it needs an update to be able to display graphics properly:

    sudo apt install libglu1-mesa-dev

    (If that's not done, I cannot compile Qt programs. Perhaps that update helps displaying them as well.)

        Hmmm, you could try installing Qt/Qt Creator in that Ubuntu VM, see if you can build and run any of Qt's OpenGL examples, for example Shader Effects (works ok on my Ubuntu VM).

          Installed Qt on the deployment test system and it appears to be be able to run examples. However, the software I am deploying still does not function appropriately and I get the same error message when I enter that portion of the program.

            What exact OS are you running ? What graphic card is the machine using ?

                The Virtual Machine to which this program is being deployed (and having issues):
                alt text
                The Virtual Machine which it was developed on:
                alt text
                As you can see they are almost identical except that the software runs properly on the development machine, and generates errors on the deployment machine:
                What it is doing:
                alt text
                What it should be doing:
                alt text
                The Actual Machine these VM's are running on is equipped with a GeForce GT635.

                  Hi just a wild guess but have you tried increasing the amount of RAM available on your troublesome VM, from 975.0 MB to say 2 GB?

                      Are there any differences between the two machines ?

                        Good news everyone! I figured it out. I needed to bring over the folder "xcbglintegrations" from the development plugins folder in Qt on the dev machine into the folder colocated the deployed program. Thank you again for all your help!

                          Add
                          export QT_QPA_PLATFORM_PLUGIN_PATH=/pathtoQT/5.x.0/gcc_64/plugins
                          to ~/.bashrc

                          source ~/.bashrc

                          This works for me.
