Hi !I manually loaded NBOpenGL from SmalltalkHub and SourceCity on moose 4.8, with the default vm proposed on moose's website and it works.There is a sourcecity and GLTest example.I tested it on win 8 64bit. It'll not work on linux. I don't know about mac os.I will update the ConfigurationOfSourceCity, but i have to write my internship's report for the moment.Sorry for the unexpected troubles_______________________________________________2013/6/6 Alexandre Bergel <alexandre.bergel@me.com>
