<pre>Compiling OpenCL code with clang requires the headers from libclc library.
Otherwise, e.g.
__kernel void test()
{
int i = get_global_id(0);
}
yields: "implicit declaration of function 'get_global_id' is invalid in OpenCL"
Including the clc headers via
#include <clc/clc.h>
works correctly with -cl-std=CL2.0 and defines the required symbols (such as
get_global_id), but it gives plenty of compile errors with -cl-std=c++,
starting with:
/usr/include/clc/math/fract.inc:23:62: error: unknown type name 'global'
_CLC_OVERLOAD _CLC_DECL __CLC_GENTYPE fract(__CLC_GENTYPE x, global
__CLC_GENTYPE *iptr);
For reference, I am using the master branch of libclc from
<a href="http://libclc.llvm.org/">http://libclc.llvm.org/</a></pre>
