py-scipy @0.16.1 +atlas build failure due to new atlas variants

[chanmhy@…]

The new revision of the atlas port released 7 weeks ago removes the +clang variant from the build. Instead, it defaults to that build if you don't specify any options.

As a result, it is now impossible to build py-scipy with the +atlas variant. Please see the attached log for more info.

Thanks for the report. Looking into it today.

Sorry, it's taking forever to build atlas :-(

[chanmhy@…]

Hahaha story of my life. No worries. Thank you for handling the ticket quickly.

I think I have a fix for this but need to test a few more things. Just need to rebuild atlas yet again.

Ok, I was finally able to build a bunch of versions of atlas and test the fix with scipy. Unfortunately, the test suite fails to run due to:

This is due to scipy using the, now removed, function cgegv. The scipy 0.17-rc2 fixes this and I just tested it. When it is released everything should run smoothly again. I'll push my local change up soon.

Fixed in r144622.
