I think you mean svn co http://lambdacube.googlecode.com/svn/trunk

I didn't do anything yet, except running the sample program. I get to see an ogre head and this:

Until this point it is OK. (sorry for the lots of debug info, i'll remove them later)

1 frames in 13.45548 seconds = 7.431916215549353e-2 FPS

The FPS calculation is wrong at first frame. I have a geforce 7300 GS and its running at ~670 FPS in 640x480 sized window. The example uses glsl shader. (if you remove robot from the scene then it will be compatible with older graphic cards too) Please press ESC to exit from example program instead of closing the window. The screenshot (http://code.google.com/p/lambdacube/) is taken from example1, you should get same one.

zsh: abort ./example1

I _think_ example1 is killed by SIGABRT, but I could be wrong, I've never seen this before. Anyway, it's a strange thing.

Does the program exit immediatly after the first rendered frame?
