Publish libtfr on conda-forge? / set up cibuildwheel?

[NickleDave]

Hi @dmeliza I'm working with @theresekoch to get this library working: https://github.com/vocalpy/sappy

Therese is on Windows and gets an error when we try to pip install libtfr.
We tried using the wheels linked in the README but it looks like those are only for 2.7 and 3.4?
https://pypi.anaconda.org/carlkl/simple/libtfr/
And just doing a direct pip install libtfr fails because there's no compiler set up, I think.

One relatively quick route to let people use on Windows might be to make a conda-forge package?
Would you be okay with me doing that?
I have done it before but only with pure Python packages.
I did test whether it would even be possible using grayskull and was able to generate a recipes/meta.yaml without failure but I would need to test more whether it actually builds.
Just wanted to run 5his idea past you before I go down the rabbit hole.

I don't have experience building wheels but if @carlkl was willing to share how they built them then I'd be open to helping you automate with something like cibuildwheel

Some time ago I proposed to use the UCRT64 environment from msys2/mingw-w64 (that is integrated into Github actions for some time now) to this project: hibtc/cpymad#81
You may take a look what they have done here: https://github.com/hibtc/cpymad/tree/master/.github

Very helpful to know, thank you @carlkl !!!

Hi @NickleDave I would be thrilled if you wanted to set something up for automated wheel builds. Right now I am doing it manually, hence the lack of anything new in the last few years.

[NickleDave]

🙌 @dmeliza glad to hear it!
Only one problem: I have no idea what I'm doing.
I know you're probably busier than ever right now, but any chance we could chat for ~0.5h and you could sort of point me in the right direction?
If you talk me through what you do by hand, I can try to take it from there and get help from cibuildwheel people I am acquainted with in US-RSE and SciPy communities.

[dmeliza]

Sure, we can find some time to chat this week. Shoot me an email and we’ll set something up.

Hi again @dmeliza sorry for the slow reply, I am recovering from SciPy conference -- I sent an email to your cdmj8 address from nicholdav, please do let me know if there's a time next week that works for you

[dmeliza]

Okay, so the good news is that I figured out how to use github actions and cibuildwheel to build and publish wheels.

The bad news is I've only got it working for Linux and MacOS, and I'm not at all sure how to make it work for windows. The standard practice for the windows users in my lab is now to install a Linux VM. But let's still chat next week and see if there's a way to get windows wheels or conda recipes out there, as I would be happy to see this library get wider use.

[NickleDave]

👍 excellent, I see the published wheels.
That at least lets me move forward with testing what we're working on with Unix.

For sure, happy to talk and see if I can be of service.
I know it would be good to have the library accessible on Windows too

Notes from talking:

• For future reference: https://github.com/melizalab/libtfr/wiki/Windows-Compilation
• How to "vendor" fftw + lapack
• Just build wheel w/in a conda env?
• and/or just use conda -- just use binaries that conda gives us
