Hi Andreas,
gave it a quick try on a Mac (OS X 10.10.3) with Anaconda Python 2.7. My
observation when building pyopencl master branch:
* you need a recent cffi
* on a Mac, the OpenCL headers reside in <OpenCL/…>, changed this in
cffi_build.py.in
* same for OpenGL headers, live in <OpenGL/…>
* still building fails with an error (only showing first error):
…

seems you are using C++ language features too recent for a Mac :-(
my result for 'gcc -v'
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.3.0
Thread model: posix
I also tried a more recent gcc (4.9, installed with homebrew) without success:
$export CC=gcc-4.9; python setup.py build
gives a huge amount of compile errors similar to:
/var/folders/4x/v77nr78x5cs7l2rjscx147th0000gn/T//ccHwGSd1.s:8:bad register
name `%rdi)'
/
I have no clue how to proceed.
thanks for your work
Gregor
