Python2 Build fails with make: *** [Makefile:426: sharedmods] Error 139

Python version: 3.6

OS: Arch Linux

python-for-android version: 0.6.0

The command I use to build is:

p4a apk --private ~/Projects/Python/Mobile_Apps/BeerApp/ --package=org.drink.recommendations --name "Drink Recommendations" --version 0.2 --bootstrap=sdl2 --requirements=python2,kivy --ndk_version r9c

The error is:

make: *** [Makefile:426: sharedmods] Error 139

The build logs are in the following file. p4a_errors.txt

Initally I thought that this was a buildozer issue, as I attempted it that way first. So, I opened an issue on their github page and multiple users pointed out that they too were experiencing this issue. I’ve tried with both python3 and python2, the out come is the same. There is absolutely no unicode in any of my source files, I’ve also attempted the build with pygame instead of sdl2 (for python 2). There are also multiple simillar SO threads open about this.

Does anyone have any sugesstions or ideas as to why this is happening and how to go about fixing it?

It’s also worth noting that if I use the kivy buildozer vm, I can use buildozer to carry out a successful build. Just not on any other machine using either buildozer or p4a, using the same source and build commands.

The buildozer issue is here: https://github.com/kivy/buildozer/issues/673

The output from the dump file is:

Works with Python 2.7.15.

Long story short, issue was a longstanding in Python < 2.7.15, and recently triggered with recent compiler. They fixed it in 3.x, and backported into 2.7.15. So instead of just gathering the patch back, maybe it’s best to update our 2.x version to 2.7.15 with the cross compilation patches. I’m a little bit afraid of the implication (ssl certificates issues on 2.7.x at some point).

I’ll fix it anyway, last time i checked python 3, i wasn’t able to have sqlite3 + ssl working. And i have few customer old app that i need to maintain, and no budget to switch to Python 3 yet. So drop it is not a complete solution for now.
