ARMv7l wheels

[ColdHeat]

Sorry if this is obvious but is it possible to use cibuildwheel to create an armv7l wheel for manylinux2014?
I've been trying it for awhile and it doesn't seem like it's doable even with the qemu emulated builds?

hey! so, the Manylinux project doesn't publish armv7 Docker images, that would be your first problem. I guess they might not be all that keen to add one at this point, armv7 is a 32bit arch and they seem to be phasing out the 32 bit archs due to spotty compiler support. But you could go ask :)

If there was a armv7 Docker image, then cibuildwheel would also need to add support for the new architecture. Not a big job, assuming it all goes smoothly! I don't think there would be a problem emulating armv7 through qemu.

I'm curious - what's your use-case for compiling armv7?

[ColdHeat]

Yeah I figured that was the problem. Perhaps there's an alternative Docker image that could be used?

My use case currently is getting Raspberry Pi wheels for https://github.com/ColdHeat/pybluemonday. Piwheels isn't building it properly b/c it uses golang and I'm trying to see if this is something I can automate myself.

[joerick]

Ah yes, I had forgotten about Piwheels! Thanks for the reminder. That's probably a better way to go for this sort of thing, I think. I see you're making some progress in piwheels/packages#197 :)

Perhaps there's an alternative Docker image that could be used?

Yes, perhaps. If you were able to find/create one, you could try plugging it into one of the CIBW_MANYLINUX_*_IMAGE options (perhaps CIBW_MANYLINUX_I686_IMAGE as that's also 32-bit). But we're getting pretty hacky at this point :)

Another idea for you, if you're interested - I just came across https://github.com/messense/manylinux2014-cross-arm, which could perhaps be used to cross-compile, here's an example usage: messense/fasttext-wheel@b6bd26d. However, I don't know how this would interact with the go binding...
