Application quit abnormally! RuntimeError

[maximereinhart]

Hi I try to make iOS app. First I'm testing with pong game from kivy tuto. I can build it but when I try to run it, the app quit suddenly. Thx for help.

In console :

File "kivy/_event.pxd", line 1, in init kivy.properties (kivy/properties.c:24779) File "", line 29, in load_module File "kivy/properties.pxd", line 3, in init kivy._event (kivy/_event.c:6585) File "", line 19, in find_module File "/Users/me/kivy-ios/build/python/lib/python2.7/posixpath.py", line 68, in join RuntimeError: maximum recursion depth exceeded in cmp 2014-11-04 13:45:28.228 pong[322:30918] Application quit abnormally! 2014-11-04 13:45:28.259 pong[322:30918] Leaving

Which cython version did you use, @maximereinhart ?

[maximereinhart]

Cython version 0.21.1 Cython/Build/Dependencies.py looks good. dir = os.path.dirname(os.path.abspath(str(filename))) if dir != filename and path_exists(join_path(dir, 'init.py')):

Same problem here with cython version 0.21.1(this app runs fine on android when build with buildozer):

File "kivy/properties.pxd", line 3, in init kivy._event (kivy/_event.c:6585)
   File "<string>", line 19, in find_module
   File "/Users/lele/code/p4a/.buildozer/ios/platform/kivy-ios/build/python/lib/python2.7/posixpath.py", line 68, in join
RuntimeError: maximum recursion depth exceeded in cmp

I think 1.8.0/stable (default) is not compatible with cython 0.21, but not sure if this is the problem here.

Maybe try to downgrade (i'm currently using 0.20.1 for ios builds), or alternatively try KIVY_BRANCH=master (which has fixed the cython incompatability)

[schemacs]

no luck after downgrade cython to 0.20.1.

I just tested building the pong app here, works as expected.

@schemacs are you also trying to build pong, or something else? Did you remove the compiled kivy and run build-kivy (or build-all) after the downgrade?

[maximereinhart]

Ok I did: $ pip uninstall cython $ pip install cython==0.20.1.

I built again kivy iOS: $ tools/build-all.sh

And pong app: $ tools/create-xcode-project.sh pong /path/to/your/appdir

And It works on my Ipad. Tthx for help !

[schemacs]

Yes, after I rebuild everything with cython==0.20.1, this run on my iPad.

Had the exact same issue and this solved it. Thanks!

Having this same problem in 2022.

Currently using Cython==0.29.28.

Tried downgrading to Cython==0.20.1 but no luck.
