Your initial hunch was correct. Nonetheless, if you must build PyOpenCL from source, you should be able to use ./configure.py --cl-pretend-version=1.2 to force the version of the header that PyOpenCL uses. Alternatively, since (it seems) you are already using Anaconda, you might as well install our binary packages in conda-forge, see here: https://documen.tician.de/pyopencl/misc.html#installation (if that's an option) HTH, Andreas
