Where could I get _ctypes module except libffi-dev? - Snake - Jan-10-2020
I have an issue with Buildozer while trying to build Kivy program for Android, when I run buildozer android debug deploy run it says no module named _ctypes . On AskUbuntu I've seen the solution for people was installing libffi-dev - a system=wide package, not package of pip. But it seems there is no such package for some other Linux distributions (like Manjaro). So, where could I get _ctypes module?
Output: .buildozer android debug deploy run

Though may be I'll figure that out myself tomorrow, after getting some rest.

You asked where to find the file.
I provided that, but sorry to say that I don't use Kivy, so can't help on that end.
Check back, another moderator may pick up.
I did run into a similar problem some time back when trying to install wxpython on Linux mint. (was failing on _ctypes)
I'll go back and check my notes to see how I over came that and if it appears that my solution will fit your case, I'll report back.
I am running Linux Mint 19.1 Cinnamon, and it seems to be related.
RE: Where could I get _ctypes module except libffi-dev? - Larz60+ - Jan-10-2020
I found my notes for the wxpython install.
USE WITH EXTREME CAUTION
this may or may not help.
First, make sure the right version of python dev is installed. I was using 3.7 when I installed wxpython
second, replace wxpython with appropriate Kivy equivalent.
you will have to find a wheel for Kivy
but once I installed all of the packages (with the apt-get) it seemed to do the trick.
This mess took me several months to get right.
finally good luck.

RE: Where could I get _ctypes module except libffi-dev? - Snake - Jan-17-2020
I was able to get Kivy working. On Manjaro I made it without any libffi.
But strange that after I tried to uninstall some pip packages and reinstalled them again I got message no _ctypes .
Why that happens with Python? I have put back what was uninstalled, it should be the same.
1.I installed these system packages (with OS package manager): make gcc jdk8-openjdk zip python-pip .
2.Then python3.7 -m pip install --user --upgrade pip wheel setuptools virtualenv (reinstallation of which caused the problem).
3.Created a virtual environment and pip install kivy gave me no _ctypes .
