ATLAS build fail on darwin

[davidak]

i tried to build ATLAS on darwin since it is marked to review in the broken darwin packages page. build all the dependencies takes about 6 hours and then fails with a Segmentation fault.

my system is OS X 10.9.5 on an Intel Core i5.

AFAIK most packages have been switched to openblas. It might be easier to switch what you need than to try fix atlas.

[ttuegel]

Speaking as a maintainer of OpenBLAS and ATLAS in Nixpkgs and a user of both, OpenBLAS is superior to ATLAS in almost every way. This is particularly true from the perspective of binary caches. The binary cache version of ATLAS is optimized for whichever Hydra node it is built on. OpenBLAS uses dynamic architecture detection so the binary cache version will be well-optimized for all the platforms we support. OpenBLAS should be a drop-in replacement for any package using ATLAS; I strongly encourage switching.

[davidak]

then we should not try to fix it and simply remove darwin from the platforms.

[vcunat]

It has no platforms set. We might put in some list where it works sensibly (the two Linux platforms?), or perhaps better set broken = true; to express it shan't be supported?
