doesn't work with buildozer/kivy : ImportError: dlopen failed: cannot locate symbol __gxx_personality_v0

[magowiz]

Hi,
I'm trying to build an android app with kivy/buildozer, using architecture arm64-v8a, shazamio-core build is fine (no error on compile), but when running on smartphone the app crashes with this error:

ImportError: dlopen failed: cannot locate symbol "__gxx_personality_v0" referenced by "/data/data/net.magowiz.musenote/files/app/_python_bundle/site-packages/shazamio_core/shazamio_core.so"...

What I miss?
from python-for-android (here: kivy/python-for-android#3030) they suggested me to add -lstdc++ to LDFLAGS but I still get the error.

Hi @magowiz,
Can you do uname -a in termux and show the result? Perhaps I will try to check and build a package for your device.

Sure, here it is:

Linux localhost 4.14.186-g7c18952d3c68 #1 SMP PREEMPT Wed May 25 19:55:45 WIB 2022 aarch64 Android

Sure, here it is:

Linux localhost 4.14.186-g7c18952d3c68 #1 SMP PREEMPT Wed May 25 19:55:45 WIB 2022 aarch64 Android

i see aarch64 in output.

And select the wheel for the desired python and aarch64 version

install command:

python -m pip install file_name.whl

[magowiz]

are they available via pypi ? In buildozer I can only put a package name, if it matches a recipe (specific instructions for that package) it will use it, otherwise downloads using pypi, I'm trying to get some information about how to use those whl inside a recipe. By the way thank you very much for providing me those packages.

I'll add them to pypi within tomorrow, I'm working late today

Sorry I forgot to update you about this: I thought that somehow since I cited the python-for-android issue 3030 (kivy/python-for-android#3030) you get some notification about that.

T-Dynamos told me that those wheels are not going to work on android, here's reference to his comment : kivy/python-for-android#3030 (comment)

So currently I'm waiting for instructions from T-Dynamos to fix my p4a recipe or some evolution in p4a to handle this.
