Hey! I've forked and now have my repo following HEAD (or at least, LKG HEAD from when I built last, as HIDAPI updates frequently :) ) of the hidapi repo, building against it directly. I'm also adding in more function support (I need things like path-based opening and feature report getting). I also brought in parautenbach's patch, and am going to try to shore up the setup.py to get this pip-worthy. It's at http://www.github.com/qdot/cython-hidapi Thanks so much for getting the base of this going! :D |

Can be changed to the following code to support 64 or 32 bit system
import struct
if struct.calcsize("P") == 8: # 64 bit
os.environ['LDFLAGS'] = "-L/usr/lib/x86_64-linux-gnu -lusb-1.0 -ludev -lrt"
else:
