Description

I was trying to add to my project a shazamio-core recipe which is a rust project, so I used the recipe class RustCompiledComponentsRecipe and wrote my own recipe, which is this:

from pythonforandroid.recipe import RustCompiledComponentsRecipe


class ShazamIoCoreRecipe(RustCompiledComponentsRecipe):
    version = "1.0.7"
    url = (
        f"https://github.com/shazamio/shazamio-core/archive/refs/tags/{version}.tar.gz"
    )
    site_packages = "shazamio_core"


recipe = ShazamIoCoreRecipe()

It compiles fine, but in android, when I launch my app I get this import 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"...

then the app crashes

buildozer.spec

Maybe you try to play with linking flags in get_recipe_env and add -lstdc++.

Something like:

    def get_recipe_env(self, arch, **kwargs):
        env = super().get_recipe_env(arch, **kwargs)
        env['LDFLAGS'] += ' -lstdc++'
        return env

Hi @T-Dynamos,
thanks for the hint, I changed the recipe in this way, like you suggested:

from pythonforandroid.recipe import RustCompiledComponentsRecipe


class ShazamIoCoreRecipe(RustCompiledComponentsRecipe):
    version = "1.0.7"
    url = (
        f"https://github.com/shazamio/shazamio-core/archive/refs/tags/{version}.tar.gz"
    )
    site_packages = "shazamio_core"

    def get_recipe_env(self, arch, **kwargs):
        env = super().get_recipe_env(arch, **kwargs)
        env['LDFLAGS'] += ' -lstdc++'
        return env


recipe = ShazamIoCoreRecipe()

I deleted buildozer home and build folders and built again, with new recipe, it builds successfully, but I still get same behavior: app crashes and on log there is same error.

Hi,
mantainer provided in a release in github some whl files https://github.com/shazamio/shazamio-core/releases , for example this: https://github.com/shazamio/shazamio-core/releases/download/1.0.7/shazamio_core-1.0.7-cp311-cp311-manylinux_2_17_aarch64.manylinux2014_aarch64.whl

How can I create a recipe that install from there ?

@magowiz This can't be used, as it's compiled for glibc, but android is bionic.

(Only wheels compiled with android-ndk will work)

I believe this error can be easily solved, I will try work on it ASAP.

[magowiz]

thank you very much!
