Re: [gentoo-user] virtual eselect - how to
Hi All,
I mentioned my active PR a few times on dev-lists that covers *openblas
ebuild (for main gentoo tree ~amd64)* + *integrated switch script between
openblas and gentoo reference set* {c,}blas, lapack and gsl (gnu scientific
library) *system-wide.* It seems i could not announce it enough.
Here is the complete openblas PR + system-wide switch script, if someone
interested in -->
https://github.com/gentoo/gentoo/pull/11700
*Here is the code who want to inspect switch script before use it -->*
https://github.com/gentoo/gentoo/blob/04b5fc9c117571ce040a94f63c6d09e0ce15c5f8/sci-libs/openblas/files/openblas
- I believe the proper way is eselect instead of this script but
openblas switch script is my quick fix until openblas fully integrated to
main tree and eselect.
- After switching to openblas system wide with script i tested it
with *numpy
& scipy, *both of them compiled with openblas support without any issue.
- *This is not officially merged PR and maybe it never will.Also switch
script not reviewed deeply by gentoo devs and may need improvement.This is
my own solution.Please consider this before use it.*

I have the feeling you're mixing ::science and ::gentoo packages. Since openblas is only in the ::science overlay, I presume you are using that. The version of virtual/blas in ::science *does* include openblas already, so you shouldn't have needed to modify it, and you should be using eselect::science, too. eselect-blas is *not* enough (and I don't even have it installed). If you want to be sure to use packages from ::science, append "::science" to packages in your world file or set definition(s). > How does eselect get the list of alternatives? I don't know, sorry. > Many thanks for a hint, > Helmut BTW, the thread Dale mentioned is part of an effort to get the BLAS/LAPACK alternatives handling done properly (or at least more robustly). The way it's handled in the ::science overlay currently will likely not be merged into the main portage tree.

I assume it doesn't know about it because there is no eselect module for blas. > I have even modified virtual/blas to include openblas. Virtual packages are there to make sure at least one of alternative packages satisfying dependency requirements will be installed. So, some package you installed requires a database. A virtual/ will be installed to make sure at least one of the database packages to satisfy the dependency requirement is installed. > How does eselect get the list of alternatives? > > Many thanks for a hint, > Helmut My understanding is package devs will have to create a corresponding eselect module, in order manage the symlinks for the various versions of said package which are available in the tree at any time. In absence of an eselect module, you can create any desired symlinks yourself. I often forget there are so many eselect modules these days. I found myself using rm and 'ln -s' to change profiles, only to recall eselect does this in a single incantation. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
[gentoo-user] virtual eselect - how to
Hi, what is the relationship of a virtual package and eselect. E.g. I have installed openblas but 'eselect blas list' doesn't know about this. I have even modified virtual/blas to include openblas. How does eselect get the list of alternatives? Many thanks for a hint, Helmut
