9 years ago I have yet to get to your build log but first thing first, is fflas-ffpack present? And if it is, what is the output of fflas-ffpack-config --libs.

9 years ago Do you even have a /usr/lib64/blas folder?

/usr/lib64/blasfolder?
Yes
fflas-ffpack-1.6.0-r5::sage-on-gentoo just finished building. Afterwards sci-libs/linbox-1.3.2-r2::sage-on-gentoo built without issues, too.
Can this brokenness be somehow detected / prevented by the fflas-ffpack or linbox ebuilds? Through (sub-)slot dependencies or something?
kiwifb
commented
9 years ago No. This is probably due to an incomplete/incorrect migration from the main tree blas/lapack infrastructure to the one of the science overlay. You shouldn't have that folder at all. https://wiki.gentoo.org/wiki/User_talk:Houseofsuns

9 years ago I followed that guide, but overlooked to set FEATURES=-preserved-libs. So maybe the folder was there just because portage preserved the library in it for linbox. I'll check later whether it is gone, now that linbox was rebuilt successfully.

8 years ago I think we can close this. You can still comment or suggest something if you wish.
sci-libs/linbox-1.3.2-r2 from sage-on-gentoo fails to build after enabling the science overlay (which sage-on-gentoo's layout.conf says is required):
build.log (It's not actually image/png but text/plain - the filename extension was only chosen to fool GitHub.)
