Thanks @dvd101x!

You'll need to merge main to get #4396 which fixes the build.

Thanks! I did the merge.

Hi Hood,

Thanks for the help with the merge suggestion.

Sadly I might need help on this one. I'm really new to this. Could you give me some pointers on my mistake?

Error building sourmash.

Not sure, looks unrelated to you since sourmash doesn't depend on coolprop. I restarted the CI, hopefully it was a flake. If not a flake and there was a change outside of this repo that caused sourmash build to persistently fail, then you could try disabling sourmash to see what happens with coolprop.

Okay on rerun we get an actual failure:

FileNotFoundError: [Errno 2] No such file or directory:
'/root/repo/packages/coolprop/build/coolprop-6.6.0/wrappers/Python'

I guess when I get a chance I'll have to try to build it locally and see what happens. Did you build it locally and succeed or are you unable to do local builds?

I can reproduce the failure locally. It seems that Coolprop does some file rearrangement on its sdist when you run setup.py and somehow our build system isn't reproducing it properly. Maybe one of the Coolprop maintainers (cc @ibell, @jowr) could give us some guidance, or maybe comparing the build logs between building a native wheel and a Pyodide wheel will show the steps that we're missing.

Could you try removing these two line and see what happens?

The coolprop archive from Sourceforge and from PyPI have different structures. I guess the line above was to workaround for the Sourceforge archive so you might not need it for PyPI archive.

I tried removing the lines for setup.py but it seems to fail quicker.

I don't have a setup ready to reproduce locally, but there is also a newer version in sourceforge that I could try instead of the one from GitHub.

Most recent failure was in scikit-image with:

http.client.IncompleteRead: IncompleteRead(11534336 bytes read, 11186083 more

Which looks like another flake regarding some sort of failed http request unrelated to this PR. I don't know why we're getting so many failed requests on this PR, it's not usually very common.

Anyways I reran it.

The build was successful, but there are test failures. Could you check and fix the test failure?

It seems it was missing some sources as mentioned in here, had to revert back to sourceforge
