 |

Hello,
I recently installed openblas and lapack from the science overlay
| Code: |
emerge lapack-reference::science openblas lapack::science cblas::science blas::science
|
They seem to be working fine, but also to have foobarred numpy. I can't emerge matplotlib in what ultimatley looks like a problem with numpy, and trying to emerge numpy dies with

Here's the patch output:

Anyone have any ideas?? |

For what it's worth, I just backed the whole thing out -- it doesn't seem like openblas plays nicely with the rest of the system. So I did emerge -C on everything, removed the science overlay, and installed the reference versions of lapack, blas, and cblas. Strangely, I needed to remove the tarball for numpy from /usr/portage/distfiles to get it to emerge again, but that did work.
I had a somewhat similar experience trying to run ROS on Gentoo (fubar'd Python that time). I ended up creating a chroot version of Ubuntu which worked well for ROS. I installed openblas and torch7 (which is what I wanted openblas for) easily in there too. So I think my take-home is that stuff that's fundamental to the system and not fully supported by the main gentoo tree is best done in the chroot. |

| So the chroot doesn't play nicely with CUDA! So now I've just installed openblas by hand in /opt/openblas. This seems to work! |
