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

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

[Tobias-Fischer]

All builds except for Windows now succeed.

@conda-forge/help-osx-arm64 @conda-forge/mumps @traversaro - could you please have a look?

[traversaro]

Random guess: set FC=flang?

[traversaro]

Actually I installed locally and even if I installed the same version used in https://github.com/conda-forge/mumps-feedstock/runs/3253545563 (last successful build) I do not have any flang.exe installed, just flang1.exe and flang2.exe, not sure why.

We could try to pass flang1 or flang2 as compiled, but it is a shot in the dark. Perhaps @conda-forge/flang may know something more.

conda-forge/conda-forge-repodata-patches-feedstock#226 should fix it

An explanation is given in mamba-org/mamba#897 (comment) . TL;DR: It is related to a difference in how conda and mamba resolve packages, and now mamba is used by default.

@conda-forge/mumps - this is ready for review. The windows build fail should be resolved by a restart of the CI in a few hours.

[Tobias-Fischer]

Thanks for the hints @traversaro @isuruf !

[traversaro]

@conda-forge-admin, please restart ci

@conda-forge/mumps - this is ready for review. The windows build fail should be resolved by a restart of the CI in a few hours.

The Windows build is now ok.
