import gevent -> ImportError: cannot import name core

[alanjds]

Trying to port the interactive console to "minimal" bootstrap, got an issue importing gevent:

ImportError: cannot import name core

Researched, and looks like "gevent is being imported from its build folder": http://stackoverflow.com/a/2312205/798575

Follows my main.py and logs:

# main.py
__version__ = '0.1'

print 'Trying to import gevent'
try:
    import gevent
    from gevent.backdoor import BackdoorServer
except ImportError:
    print 'Failed. Trying to fix the path'
    import os
    print 'PATH:', os.sys.path
    print 'PWD:', os.getcwd()
    os.chdir("..")
    print 'PWD:', os.getcwd()
    print 'Trying to import again'
    import gevent
    from gevent.backdoor import BackdoorServer

print 'Success. Trying to bring the console shell'
server = BackdoorServer(['127.0.0.1', 5001],
                        locals={'foo': "From defined scope!"})
server.serve_forever()

Bash commands used to build the APK:

./distribute.sh -b minimal -m 'python gevent pyasn1 pycrypto pyopenssl'
./build.py --package org.minimal.test --name _MINIMAL --version 1 --asset --private ~/src/git/p4a-minimal-shell/ debug installd

I dont see this "fixed", but looks like nobody cares anymore. If redoing it, I would go with Python3+asyncio anyway.

Yes to be honest, this was probably closed as stale since as you said nobody seemed to care.
But if you've tried again and confirm it's still an issue then maybe we/you should take a look.
As far as I remember I've already played with gevent in one of my apps. Well it was a sub dependency and I haven't tried importing it directly.
So do you confirm this is still an issue? On p4a master? If so please reopen with updated debug log and way to reproduce
