This package contains native components, so it would have to be built into an Android wheel file. If you'd like to try doing this 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.

From the error message, it looks like this package uses the Meson build system, which the build tool isn't compatible with yet. If there's an older version that uses Setuptools instead, you should probably try building that first.

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

@mhsmith Can you please explain this in the Chaquopy packages Readme

Use pip to install the requirements.txt in this directory.

Use your distribution's package manager to install the following build tools:

patch patchelf Depending on which package you're building, you may also need additional tools. Most of these can be installed using your distribution. Some of them have special entries in the build requirements section of meta.yaml:

fortran: You must install the Fortran compiler from here. Create a fortran subdirectory in the same directory as this README, and unpack the .bz2 files into it.

Is there any example of this step-by-step process?

thanks

[mhsmith]

I'm not sure how I can make these instructions any clearer. But there's no need to install Fortran unless the package actually needs it, which is unlikely.
