I had to add some more stuff to accomodate apple's weird define for the
context property, also with apple you can't use createContextFromType to do
GL sharing, so the user has to pass in an empty device array if on apple.
(also we don't pass in the platform to the properties array when doing GL
sharing on apple)
I do like the improvements with pyopencl.tools function call, makes it much
nicer for the user!
Also as a side note, when building from git
git submodule init
git submodule update
did not seem to get all of the dependencies for pyopencl (it was missing
ptr_container) so I manually pulled from bpl-subset.git and replaced the
bpl-subset folder inside pyopencl
Should be fixed in git.
This still didn't work for me =\ I checked out a fresh copy of the repo to
test the changes and bpl-subset still seemed to be missing files:
src/wrapper/mempool.hpp:12:43: error: boost/ptr_container/ptr_map.hpp: No
such file or directory
src/wrapper/mempool.hpp:14:28: error: boost/format.hpp: No such file or
Copying the actual bpl-subset directory worked again tho.
Thanks for your contribution!
