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.

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

Here's what I've got...

For recipe:

• Selectors are suggested to take a <two spaces>#<one space>[<expression>] form. See lines [22]

We will need to add pycairo to the migration. CF only has Linux / Win packages, but defaults does provide ppc64le. We shouldn't take it from there though.

ppc64le fails with:

[  1%] Building CXX object Code/RDStreams/CMakeFiles/RDStreams.dir/streams.cpp.o
powerpc64le-conda_cos7-linux-gnu-c++: error: unrecognized command line option '-mpopcnt'; did you mean '-mpopcntb'?
make[2]: *** [Code/RDStreams/CMakeFiles/RDStreams.dir/build.make:80: Code/RDStreams/CMakeFiles/RDStreams.dir/streams.cpp.o] Error 1

However I don't see this option in build.sh and I don't think the compilers include this unrecognized flag, so I guess it's part of rdkit's CMake configuration?

--edit-- Yes, discussed here: https://github.com/rdkit/rdkit/issues/2405

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

I was trying to look for recipes to lint for you, but it appears we have a merge conflict. Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Ok, this should work on the next release. There's a subtle issue for ppc64le that will be addressed in the next release. See https://github.com/rdkit/rdkit/pull/3285 for details.

I suggest waiting until then to update this PR and merge without patches.

@mcs07, @pstjohn, would you mind if I added myself as a maintainer?

[mcs07]

Go for it! Thanks for all your work on this PR.

HTTP error in ppc64le, retrying...

[jaimergp]

There's a new error with CMake I am investigating.

[jaimergp]

Let's see if it was a weird conda solver issue.

[jaimergp]

Well, that did it! Ready for review @mcs07!
