Made some progress: some (very few) demos are running now.
Here's my question:
Are most of the demos supposed to run in Windows only?
I've found most of them are using "GLWin32Viewer" which I suspect only works for Windows.
The few demos I found that work in Linux are all using GLLCLViewer instead (like e.g. ../bench/megacube).
Is this true or could there be something else wrong?
EDITMaybe I make it to No.1 canditate for the 1 million monkeys coding theory...
All I needed was to replace GLWin32Viewer to GLLCLViewer, that's all.
The first 2 demos which didn't run before are running now!
