Hi,
I’m new to CUDA. I have limited access to a desktop machine containing a GTX280 however the plan is to do most of my developing on a MacBook (2007) running 10.5.4 in emulation mode. The MacBook has an Intel GMA 950 integrated graphics card.
I’ve downloaded and installed the Mac CUDA Toolkit and SDK, and I’ve been able to build and run some of the sample applications. However, I’m getting errors with some of the OpenGL sample applications. Although I can run “FluidsGL”, when I run other OpenGL samples such as simpleGL or oceanFFT I get an error:
ERROR: Support for necessary OpenGL extensions missing.
For example, if I try the following:
./boxFilter
Loaded ‘./…/…/…/projects/boxFilter/data/lena.ppm’, 512 x 512 pixels
Error: failed to get minimal extensions for demo
This sample requires:
OpenGL version 1.5
GL_ARB_vertex_buffer_object
GL_ARB_pixel_buffer_object
What I don’t get is that OpenGL Extensions Viewer says that I have these extensions (see below).
Any idea what’s going on here?
Cheers,
Chris

Latest version of display drivers found
According the database, you are running the latest display drivers for your video card.

No compiled vertex array support
This may cause performance loss in some applications.

Multitexture support
This feature accelerates complex rendering such as lightmaps or environment mapping.

Secondary color support
This feature provides an alternate method of coloring specular highlights on polygons.

S3TC compression support
This feature improves texture mapping performance in some applications by using lossy compression.

Vertex array range support
This feature improves performance in some applications by using AGP for dynamic vertex transformation.

Texture edge clamp support
This feature improves texturing quality by adding clamping control to edge texel filtering.

Vertex program support
This feature enables a wide variety of effects via flexible vertex programming (equivalent to DX8 Vertex Shader.)

Fragment program support
This feature enables a wide variety of effects via per pixel programming (equivalent to DX9 Pixel Shader.)

Texture anisotropic filtering support
This feature improves the quality of texture mapping on oblique surfaces.

Point sprite support
This feature improves performance in some particle systems.

OpenGL Shading Language support
This feature enables high level shading language for shaders.

Frame buffer object support
This feature enables render to texture functionality.
