Solution: Add CL_PRETEND_VERSION = "1.1" to siteconf.py. Problem: If you feed PyOpenCL headers for CL 1.2 and then compile against an ICD loader that doesn't implement 1.2 functions (e.g. clCreateSubDevice), then you get this breakage. The above fixes that, by forcing PyOpenCL to ignore 1.2. Andreas _______________________________________________ PyOpenCL mailing list [email protected] http://lists.tiker.net/listinfo/pyopencl
