To install the program :
sudo dpkg -i gcode-ripper-installer.deb
This will install the files in the ~/opt/ dir. And it will create a lightning menu starter in the programming section.
When starting fails, try a sudo ldconfig $PWD from inside the extracted
~/opt/gcode-ripper/ directory to let linux know where to search for library's.
When using the source code, the project was build inside the ~/opt dir.
The gcode-ripper-source.tar.gz contains a presious opencascade qt project library.
Visit it by sniffing into ~/oce-upstream-V7_5_0beta/adm/qmake/
If you search for glbegin when the qt project is loaded, you will find the opengl intrusions.
