pyinform issue

[VWE22]

I'm working on a project that uses the lib "pyinform".
I don't have any issue when I install the lib but at the moment of execution I have the above message appear:

OSError: dlopen failed: library "libm.so.6" not found: needed by /data/data/com.example.a_example/files/chaquopy/AssetFinder/requirements/pyinform/inform-1.0.0/lib/linux-x86_64/libinform.so.1.0.0 in namespace clns-6

The none-any wheel of this package on PyPI contains pre-compiled libraries for Linux, Mac and Windows, but none of those will work on Android.

If you'd like to try building an Android wheel yourself, follow the instructions here. And if you're successful, please make a pull request so we can add the package to the public repository.

If anyone else wants this package too, let us know by clicking the thumbs-up button above.

Hello,
Thanks for your answer. I'm trying to follow the instruction [to build pyinform] but I have this error:

Installing NDK: this may take several minutes
/home/ab/Desktop/android-sdk/ndk/22.1.7171670/toolchains/llvm/prebuilt/*/bin/llvm-ar does not exist

BR

I've had several other reports of this NDK installation issue, so I've created a new issue for it: #1084. Please continue the discussion there.

The NDK exist now with the command that you give me.
Now I'm facing another error:

The yaml file is:

And I have a LICENSE file in the directory:

~/Desktop/PyInform$ ls ../chaquopy/server/pypi/packages/pyinform/
build  
LICENSE  
meta.yaml

Thanks

Apparently they forgot to include the LICENSE file in their sdist on PyPI, even though their setup.py script uses it. I suggest you report that to them.

Meanwhile, you can work around this by adding the LICENSE file yourself. See "If any changes are needed to make the build work" in the build-wheel README.
