Hi! This is the friendly automated conda-forge-linting service.

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

Here's what I've got...

For recipes/cocotb:

• Non noarch packages should have python requirement without any version constraints.
• Non noarch packages should have python requirement without any version constraints.

@conda-forge/help-python-c need some help diagnosing behavior, it looks like the first build works fine but then subsequent versions end up with errors like:

ERROR (cocotb,lib/python3.9/site-packages/cocotb/libs/<all the libs>): lib/python3.8/site-packages/cocotb/libs/libgpi.so not found in any packages

e.g. during the build for 3.9, its looking for libs from 3.8.

on OS X its similar, except it builds 3.10 before 3.9

ERROR (cocotb,lib/python3.9/site-packages/cocotb/libs/libpygpilog.so): lib/python3.10/site-packages/cocotb/libs/libgpilog.so not found in any packages

Can't seem to build 3 versions at the same time so will limit to one until the feedstock is rendered.

I started trying to look at this because it's really weird. It has been a really long time since I looked at the overlinking checks code but I'm starting to think this is definitely an issue with how conda-forge's build_all.py is building multiple versions and state in the overlinking checks is bleeding from one build to the next. I don't know if I'll find time to look at this any more but there may be something really broken here in the infrastructure. I think restricting it to a single python until you're in the feedstock and the builds are isolated is a good idea.

@isuruf / @conda-forge/staged-recipes i opened conda/conda-build#4821 but seems it will be a wait, since this issue only effects in staged-recipes can we merge this and get the feedstock rolled out?

Merge when builds pass.
