Add atool2

[jonashaag]

I don't know why we need this

/configure --prefix=$BUILD_PREFIX

but it works. It doesn't work with

/configure --prefix=$PREFIX

• Package does not ship static libraries. If static libraries are needed, follow CFEP-18.
• Build number is 0.
• A tarball (url) rather than a repo (e.g. git_url) is used in your recipe (see here for more details).

I wanted to let you know that I linted all conda-recipes in your PR (recipes/atool2/meta.yaml) and found some lint.

Here's what I've got...

For recipes/atool2/meta.yaml:

• noarch packages can't have skips with selectors. If the selectors are necessary, please remove noarch: generic.

Note that noarch packages are built on Linux and installed on macOS and Windows. What is happening with the Windows build here? Anything that is arch specific won't allow this to become a noarch package later.

[jonashaag]

Could it be the case that noarch: generic packages are not built on Linux? This is the failed pipeline https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=991382&view=logs&j=240f1fee-52bc-5498-a14a-8361bde76ba0&t=7c0f8eae-6d6f-51bf-636f-73a1a7fb1bc4

It is missing automake:

Encountered problems while solving:
  - nothing provides requested automake

Could it be the case that noarch: generic packages are not built on Linux?

They are built only on Linux in the feedstock. If you are sure this can be noarch generic, we can ignore that Windows failure and make it noarch here. We just need to be sure there are no compiled stuff there and that the files will be placed in sane directories for all OSes.

[jonashaag]

This is how it's done for atool (which is an abandoned version of atool2) https://github.com/conda-forge/atool-feedstock/blob/main/recipe/meta.yaml

Which I guess is what you're suggesting here

[ocefpaf]

The original atool seems to be a perl script dropped in a bin directory, right? Did you ever try to use that on Windows? My guess is that it won't work b/c it should be in the %PREFIX%\Library\bin. On Linux and mac that is $PREFIX/bin.

TL;DR I'm not sure how to best make this noarch generic. You can try OS-noarch and build it once for Linux+mac and they another build for Windows. However, all that won't matter here b/c your Windows build is not working. Can you propagate this comment to an issue in the feedstock. We can merge this as-is for now.
