Hi,

I’m a newbie here and I’m trying to figure out an error in my kernel, I got this log:

ptxas application ptx input, line 17; fatal   : Parsing error near '.str': syntax error

ptxas fatal   : Ptx assembly aborted due to errors

error   : Ptx compilation failed: gpu='sm_13', device code='anonymous_jit_identity'

: Retrieving binary for 'anonymous_jit_identity', for gpu='sm_13', usage mode=''

: Considering profile 'compute_10' for gpu='sm_13' in 'anonymous_jit_identity'

: Control flags for 'anonymous_jit_identity' disable search path

: Ptx binary found for 'anonymous_jit_identity', architecture='compute_10'

: Ptx compilation for 'anonymous_jit_identity', for gpu='sm_13', ocg options=''

Here my kernel:

#pragma OPENCL EXTENSION cl_khr_byte_addressable_store : enable

__kernel void OutputTest(__global char* outBuf, int sizeX, int sizeY) {

	unsigned int idx = get_global_id(0);

	if(idx >= sizeX)

		return;

	outBuf[idx*sizeX] = "Hello me\n";

}

Thank you for your help:)

The error message may not be the best one to describe the actual error. The problem is that outBut[idxsizeX] is of type ‘char’, while “Hello me\n” is of type char. This should be and error in ordinary old-school host C code as well. OpenCL it not intended to work with strings, but what you want could be achieved with something like

outBuf[idx*sizeX + 0] = 'H';

outBuf[idx*sizeX + 1] = 'e';

outBuf[idx*sizeX + 2] = 'l';

.

.

.

outBuf[idx*sizeX + 8] = '\n';

outBuf[idx*sizeX + 9] = 0;

Oh thank you for your help. I was fixed on multidimensional array yet, and I forget to change the way I wrote to buffer, The compile error is not very helpful its true:\

Thank you:)
