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.

is this still necessary? all red.

[isuruf]

Yes, need to fix this for clang.

@conda-forge-admin, please rerender

(local rerender seemed to hang; no progress after ~20+ min)

[h-vetinari]

Rerender is broken, removed.

[hmaarrfk]

I remember that rerendering this takes about 40 mins ;)

tmux + go do something else!

I did see a bug in smithy where you have to rerender twice and it alternates between a good one and a bad if I remember correctly. I never tracked it down. That might have been for this feedstock. I am not sure.

@isuruf, I may have fixed this now. 🙃

[isuruf]

Thanks

So the cross-compiled s390x targets are failing with

libtool: install: warning: relinking `libasan.la'
libtool: install: ...
libtool: relink: ...
collect2: fatal error: ld terminated with signal 9 [Killed]

but the native s390x compilers passed, so this should sort itself out upon restart I guess...

IMO we should merge and see (not least given the lack of usage of s390x compilers) - WDYT?

[isuruf]

Come on. What's the hurry? You are not even a maintainer of this repository.

I'm removing this commit and resending the PR.
