Conda-build: conda-convert for IBM Power architecture

[electronwill]

Our continuum-docs package contains html and data files but no running code. Currently we build it on macOS and then use conda-convert to make packages for 32 and 64 bit Linux and Windows. Would be good to make it available to Power users as well.

(There was another request at https://github.com/conda/conda-build/issues/834 for conda-convert on armv7l.)

[mandeep]

Shouldn't be a problem. I think the only things that need to change when converting from macOS to ppc64le would be the arch and subdir in index.json.

I'll add armv6l, armv7l and aarch64 to the list of platforms for conda convert to target. The full list of platforms conda currently is aware of is in constants.py

[electronwill]

Hm... linux-ppc64le linux-armv6l linux-armv7l and linux-aarch64 seem to be on that list currently on the branches master, 4.3.x, and 4.4.x, and they all say the file hasn't been changed in several days. However, when I updated conda to 4.3.30 and conda-build to 3.0.28 and ran "conda-convert -p all filename" I got linux-32 and linux-64 but nothing labeled as ppc64le. Was I just using the wrong command?

[mandeep]

The all flag will pull the architectures from here:

Thank you!

Should "-p linux-ppc64le" be working now, or will that take more work to enable?

I'm working on a PR now to incorporate this. There are a few changes that need to be made to the code apart from the list of platforms.

Great! Sorry for the noise.
