Missing wheels for M1 (Mac ARM) architecture

[thomasaarholt]

Expected behavior and actual behavior.

I expected to be able to install fiona with pip in python 3.9 on an M1 (arm architecture) Mac.

Steps to reproduce the problem.

pip install fiona raises the following error:

❯ pip install fiona

Operating system

Mac OS X 12.2.1.

This is in the same vein as #1028. It would be great to add arm architecture support so that fiona and its 247 downstream packages can be used on arm :)

The linux arm package is of interest for mac as well, since docker images that run on the M1 architecture will run arm arch linux. (So if you run a docker image natively on M1 mac, the current linux package will not be installed)

Fiona 1.8.21 wheels for x86_64 manylinux2014 and macos (10.10) only were built on GitHub actions using https://github.com/sgillies/fiona-wheels.

I get it @thomasaarholt, and I'm sorry to have no good news for you today.

In the M1 case, we're mainly blocked by the lack of free CI with native M1 workers. Cross-compilation is, in theory, possible, and I've done it for the GEOS library, but there are a lot of unknowns for the deep stack of libraries that GDAL depends on.

For the time being: use packages from conda-forge. The conda-forge project's mission is to build packages. You can even sponsor the project with money to do it. The Fiona project is not currently on a mission to build packages for every available platform. This is a software code project, not a packaging or distribution project.

I'm also running in to issues with installation on Apple Silicon (and MacOS 13 Ventura). Looks like Github have M1 runners in beta (see here). Using conda-forge is simply not an option for me at the moment sadly. The very nature of being a software project means it should run on an array of architectures. I don't think that's an unreasonable requirement. Any way round this other than "use conda-forge" in the meantime would be a great help to quite a few folks I'm sure!

@thomasaarholt I encountered the same issue. As you mentioned the installation complaints about a missing GDAL config. Try installing gdal with brew before pip-installing fiona again. Have a look at this thread on stack overflow :)
