pyv4l2's Issues

Unable to install in ARM

Hi,
I've downloaded this module in odroid xu4 of ubuntu 16 with kernel 3.10. I'm not able to install this module in python2.7. My error is: arm-linux-gnueabhif-gcc failed with exit status 1.
Thanks for help.

Can't find all Cython dependencies

Trying to cythonize the v4l2.pyx complains about not finding cmman and cselect. Are these custom made bindings that should be included in the repository? I can't find any references to such Cython libraries anywhere.
