clGetDeviceIDs returned -32

Accelerated Computing CUDA CUDA Programming and Performance

Hi everybody,

I downloaded and installed from [url=“http://developer.nvidia.com/object/cuda_3_1_downloads.html”]http://developer.nvidia.com/object/cuda_3_1_downloads.html[/url] the driver and the cuda toolkit. Both for ubuntu 9.10. with a Quadro FX 580.

I ran make to create the examples and they work without problems.

Then I tried following example code - [url=“http://svn.clifford.at/tools/trunk/examples/cldemo.c”]http://svn.clifford.at/tools/trunk/examples/cldemo.c[/url] - which resulted in an error message: " OpenCL Error: ‘clGetDeviceIDs(NULL, CL_DEVICE_TYPE_GPU, 100, devices, &devices_n)’ returned -32! "

How can I solve this problem? What steps do you recommend to debug?

You can’t pass NULL for the platform ID; you have to query available platforms with clGetPlatformIDs and use one of the returned platforms.

Thank you, it seems to me the example is not up to date anymore.
