pycrypt's Issues

Error installing pycrypt on Raspberry Pi 3

So after the latest commit, the -march=native argument when compiling with gcc is causing an error on Raspberry Pi 3 due to cpu auto-detection not working there (see https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=139091&p=922980)

It says I could update gcc to gcc6, but then the gcc6 command must be used, as gcc will still be the old one. It also says this fix is backborted to gcc4, but raspbian has not updated it yet.

Would it be possible to check if using a Raspberry PI 2/3 after setup.py:11, then instead of adding "-march=native", add "-march=armv8-a" for RPi3 only or "-march=armv6" (or just remove -march=native option) to build for all RPis. (copy pasted from url above)

Add Cython as requirement

Most of us have it installed from one source or another but RocketMap Travis is complaining because of using Cython without being installed first as it is not required.
For example: https://travis-ci.org/RocketMap/RocketMap/builds/222553820
