Successful Compilation under Android Termux

[defencedog]

I had installed previous version without any error but upgrading gives this error. Current installed version

~ $ pip list| grep phase
phasepy                            0.0.51

New version error...

Hey!

This is compilation error that comes from the cython part of phasepy. As you can see here, I have uploaded pre-compiled versions of phasepy for Python 3.6, 3.7, 3.8, and 3.9 for Windows. In any other case, pip will not find the wheel and attempt to compile. Which Python version and OS are you using? If using Windows, you could get the pre-compiled wheel if you use Python <=3.9. If using linux/mac os, you could easily get the compilers (and then the installation should proceed without any issues).

Regards, Gustavo

I am on Android arm64 with python3.9

Hi, I'm not sure how to proceed here. I don't think arm64 should be any issues, as phasepy works just fine on the M1 processor. However, I'm not sure how to compile specifically for an environment on Android e.e
