Set up a conda-forge feedstock

[msyriac]

I have no idea how to do this, but given that lots of people use conda, addressing #44 in #94 (pip wheels) is not enough to realize our dream of distributing binaries. So I'm adding it as an issue.

@msyriac, @JBorrow, @amaurea please check here: conda-forge/staged-recipes#27279

If you want to be a maintainer, otherwise let me know to remove you.

[JBorrow]

We need a fortran compiler as well as a C compiler

[msyriac]

Happy to be listed as a maintainer

[iparask]

I will add the fortran compiler. Can you add the maintainer acceptance comment in the PR? The reviewers will check there

[iparask]

Does pixell assume a specific fortran compiler version: https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=1014635&view=logs&j=6f142865-96c3-535c-b7ea-873d86b887bd&t=22b0682d-ab9e-55d7-9c79-49f3c3ba4823

Line 12674.

Also the whole code has warnings for tabs. I will try to silence it, but I would prefer spaces.

[msyriac]

It does not; it has worked with many recent versions of GNU and Intel. I haven't looked at it in detail, but a quick glance looks like this error isn't related to the compiler but how the build has been set up (it's trying to find calc_weights which is defined in interpol.F90)

[iparask]

I silenced all the warnings with - FFLAGS=-Wno-tabs -Wno-conversion -Wno-unused-variable and it still fails.

Lines 1505 - 1523

The function is wrapped and that shows in line 1432. There is something else here that is happening which I am not sure. I'll try a few more possible solutions and I'll see

The conda-forge recipe was merged. That sets pixell to be part of the conda forge channel.

Their bots have already created a feedstock repository (https://github.com/conda-forge/pixell-feedstock). As soon as that is populated it will create the image.

This will be the repo that we need to keep up to date for pixell to continuously be part of conda-forge
