Description

I use numpy in my code, and use buldozer to build app, building is ok, but app broke when run my app in Android.
And this error disappear if not import numy.
I have try numpy 1.15, 1.16, they are same, but 1.14 build fail!

It seems like Issue 1678, but I have not use opencv.

Thanks for the report, not sure what's wrong here - the error is clear enough, but I don't know why that symbol would be missing and didn't find anything in a quick google. I'll try to reproduce.

I use python-for-android and get the same issue:

dlopen failed: cannot locate symbol "__fixunstfsi" referenced by .../numpy/core/multiarray.so"

python-for-android is installed from git repository using pip. Arch of armeabi-v7a works well, but arch of arm64-v8a gets runtime error as mentioned above.

My building scripts:

export ANDROIDAPI="26" # Target API version of your application
export NDKAPI="26" # Minimum supported API version of your application
#export ANDROIDNDKVER="r17c" # Version of the NDK you installed

p4a apk --arch arm64-v8a --private $HOME/build/wvhellopy --package=org.example.myapp --name "My application" --version 0.1 --bootstrap=sdl2 --requirements=python3,kivy,numpy,opencv,setuptools,pytz,pip

I've tried the following ways:
1 Googled without results
2 Run "strings multiarray.so" and get symbol __fixunstfsi, no other .so files having this symbol
3 Grepping source code of numpy, no symbol __fixunstfsi found
4 Set LD_LIBRARY_PATH to every .so paths(including /system/lib64)
5 Changing init.py which is in recipes/numpy directory, adding '-lm -lcompiler_rt' without success

Maybe it is a stub function added by compiler, but I cannot figure out how.

Look like related to soft float

I ran into the same error. It only happens on for me arm64-v8a which is a problem, since to release an app you have to provide both armeabi-v7a and arm64-v8a APKs to publish in google play...
