I have been having a bit of trouble compiling a kernel with a static array of integers. When compiling the kernel (see code below) on the GPU, I receive the following:
For test only: Expires on Sun Feb 28 00:00:00 2010
CL Error: clBuildProgram (-11)
Build Log:
Link failed

And, when compiled for the CPU, I receive:
For test only: Expires on Sun Feb 28 00:00:00 2010

Any ideas? Note that if the only line of code in the kernel is the array declaration, the same result is obtained.
__kernel void combination(const int n, const int k, __global int *out) { size_t gid = get_global_id(0); int a
; int index = gid*100; for(int i = 0; i < k; i++) a = gid+i; while(index != -1) { for(int i = 0; i < k; i++) out[index++] = a; int j = k - 1; if(a < n - 1) { ++a ; continue; } while(a - a[j-1] == 1) --j; if(j == 1) { index = -1; continue; } int z = ++a[j-1]; while(j < k) { a = ++z; ++j; } } }
