Question

I have some OpenCL kernels that aren’t doing what they should be, and I would love to debug them in Xcode. Is this possible?

If not, is there any way I can use printf() in my CPU-based kernels? When I use printf() in my kernels the OpenCL compiler always gives me a whole bunch of errors.

Answer 1

Casting the format string to const char * appears to fix this problem.

This works for me on Lion:

printf((char const *)"%d %d\n", dl, dll);

This has the error described above:

printf("%d %d\n", dl, dll);
