Hi all,
I need to include some .h files into .cl OpenCL kernels but I haven't found a way to solve it.
My problem is described as follows:
1.
(1) a kernel in example.cl file:
__kernel void example_kernel(length m, length n){
....
}
(2) type length is defined in test_header.h (in the same directory of all the other files)
typedef int length;
(3) According to OpenCL Spec, adding -I when building program
ciErrNum = clBuildProgram(cpProgram, 0, NULL, "-I ./", NULL, NULL);
But this doesn't work, the program got crashed at this line, the log of building program showed:
"/tmp/OCLkQF3NK.cl", line 2: error: overloaded function "length" is not a type
name
__kernel void example_kernel(length m, length n)
^
"/tmp/OCLkQF3NK.cl", line 2: error: overloaded function "length" is not a type
name
__kernel void example_kernel(length m, length n)
^
2 errors detected in the compilation of "/tmp/OCLkQF3NK.cl".
Internal error: clc compiler invocation failed.
2. I tried again to include test_header.h in .cl file (I know this is forbidden in OpenCL Spec)
The program still got crashed when building, and the log became:
"./test_header.h", line 2: error: "length" has already been declared in the
current scope
typedef int length;
^
1 error detected in the compilation of "/tmp/OCLmy1VZ1.cl".
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Previously I just redefined them as Macros in the kernels to avoid including headers. But now, too many functions from the headers are needed, so I need to find a way to import the headers for kernel.
Is anyone seeing what could be the problem? I really need help with this.
thanks
