lxml and requests recipe: build interrupted, "_ctype" error
See original GitHub issueVersions
- Python: 2.7.15
- OS: Ubuntu 18.04
- Kivy: master
- Cython: 0.28.6
- Buildozer: 0.40 dev
- p4a: master (date: 9-10/02/2019)
Description
The apk build completes successfully with the following requirements: python2, openssl, lxml, requests, kivy. When I try to build with python3 instead, the build fails with error:
ModuleNotFoundError: No module named '_ctypes'
The error is produced while the “setuptools” recipe is being built. The problem seems to be with “lxml” and “requests” modules and/or their dependencies. Without them the apk builds fine.
I wish I had a better explanation. I don’t, I am sorry. I run quite a few tests changing the order of the requirements, messing with the recipes themselves but I always got a ‘dependency graph’ issue.
I have been following tickets, #1576, #1590, #1617 and #1564. This one seems to be directly related to them.

#[app@demo]
#title = My Application (demo)

#[app:source.exclude_patterns@demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

Building the apk succeeded!!
So, I have to correct myself: lxml and requests recipes are fine. However, hostpython requires libffi-dev so libffi-dev should be installed on the system. If so, setuptools gets build and so do lxml and requests modules, since they depend on setuptools.
One thing remains to be checked: If cffi module is needed. I guess not(?) I will check this tomorrow.
@AndreMiras, thanks for the help. Your last post was a revelation!
