Update : I started over again using a fresh install, and got to the same point. The GL sample still fails to load with the same error as before, but the console and C# samples are different now. I hadn’t mentioned it before, but I followed the instructions given here for the glut setup.
The nuitrack_console_sample works perfectly fine now, and I get the following error when attempting to run the nuitrack_csharp_sample :
Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'nuitrack.net, Version=1.0.7173.22851, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
at nuitrack.Program.Main()
Now the fact that the C# sample doesn’t work doesn’t really bother me, as I do not intend to use the language. So if this error doesn’t help finding the cause of the problem preventing nuitrack_gl_sample to work, it can safely be ignored.
