Kivy(Buildozer) compilation with Openssl stop due to a peculiar building error

[Samy Lahfa]

So I am trying to build(with buildozer) a simple app for android, with Openssl and it doesn't work, I'm on Archlinux, and I use Python 2.7, I have another Python, Python 3.6 but I don't think they're colliding.

I have replaced my account's name by xxxxx just for security purposes, and I'm not using any Virtualenv.

I have this error that shows up at the last lines of the log :

It seems it is from the building of openssl but if someone could help me get further down this issue and get the root of the problem it will be a big help.

Also, I need to build openssl because my app needs to import _ssl, if there is another way to import _ssl feel free to tell me.

Try to add futures and requests after openssl in your buildoser.specs

It is still the same error, it seems to be while building the pyopenssl module the build fails due to some weird declaration in the building of the module.

So apparently the fix to this issue is here : https://groups.google.com/forum/#!topic/kivy-users/Qt0jNIOACZc

It works now just by changing the  C code, and rebuilding.
