Running Ubuntu 10.10 with automatically installed nvidia-current driver, version 260.19.06.
Installed CUDA Toolkit for Ubuntu Linux 10.04 64 bit from CUDA Toolkit 3.2 Downloads | NVIDIA Developer
http://www.nvidia.com/object/thankyou.html?url=/compute/cuda/3_2_prod/toolkit/cudatoolkit_3.2.16_linux_64_ubuntu10.04.run
Installed “GPU Computing SDK code samples and more” from OpenCL | NVIDIA Developer http://developer.download.nvidia.com/compute/cuda/2_3/opencl/sdk/gpucomputingsdk_2.3a_linux.run into default directory ~/NVIDIA_GPU_Computing_SDK
Built CUDA stuff via “cd ~/NVIDIA_GPU_Computing_SDK/C/ ; make”. Got 6 files in /NVIDIA_GPU_Computing_SDK/C/bin/linux/release, all run, and generally say things like “TEST PASSED”.
Built OpenCL examples via “~/NVIDIA_GPU_Computing_SDK/OpenCL/ ; make”. No errors. Everything in ~/NVIDIA_GPU_Computing_SDK/OpenCL/bin/linux/release says something including “!!! Errror # -32 at line…”

Hey look, a pattern.
Any idea what the problem is?
Using Device 0: “GeForce 9300 GE”
$ lspci | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300 GE] (rev a1)
Somebody else was able to get OpenCL working on Ubuntu 10.10: The Official NVIDIA Forums | NVIDIA
“Error code -32 means CL_INVALID_PLATFORM, so I think you can run oclDeviceQuery sample to check if you are working on a valid platform.”
“You’re passing null in for the platform. You now have to pass in a valid platform object to create a context.”
$ ./oclDeviceQuery

OpenCL Device Info:
There are no devices supporting OpenCL (return code -32)
http://www.nvidia.com/object/cuda_gpus.html#Q2
GeForce 9300 mGPU, GeForce 9300M GS, GeForce 9300M G are listed as supported. Is my 9300 GE really not supported?
