Radeon Shaders Broken.

I did a few more tests... It appears libGLEW v1.5.2 does not properly detect, and that is what causes the framebuffer object to not work

Phew, glad that finally got sorted out.

vdrift: include/cartelemetry.h:63: void CARTELEMETRY::Update(double): Assertion `file' failed.

I think this is happening because it's trying to write telemetry to a file in whatever folder you're launching the executable from. It shouldn't be doing that (we should write any telemetry to the ~/.vdrift folder, and probably only with a command-line switch to enable telemetry). In the mean time you should be able to get this to work by running the executable from a folder where you have write permissions like /tmp or ~.

Should be fixed in R2842.

Same problem in today svn code and an nvidia geforce g103m, nvidia driver 256.53. GLEW v1.5.1.

Code:

glewinfo | grep framebuffer
GL_ARB_framebuffer_object:                            MISSING [OK]
GL_ARB_framebuffer_sRGB:                              OK
GL_EXT_framebuffer_blit:                              OK
GL_EXT_framebuffer_multisample:                       OK
GL_EXT_framebuffer_object                             OK  
GL_EXT_framebuffer_sRGB:                              OK
GL_NV_framebuffer_multisample_coverage:               OK
GLX_ARB_framebuffer_sRGB:                             MISSING
GLX_EXT_framebuffer_sRGB:                             OK

Dandel's fix is the only solution that worked for me.

I actually have a better fix for the overall problem... Integrate the latest release of glew into the source tree... glew v1.5.2 or older has bugs with GL_ARB_framebuffer_object.


also ilguido, you can download the latest release of glew instead of applying the patch i stated.

That's not a bad idea. I'll look into it.
