Sage Math on Gentoo

2021-03-23 :: gentoo, tutorial, mathematics

By: Maciej Barć

Intro

Sage may be available on your distro but on Gentoo such frivolities for students are not there yet, so I had to install it the manual way.

User

I went to the Sage website, to the "download-source" link. The source mirror I picked was France.

Ok, so let's follow Sage Math build instructions and get it going

wget www-ftp.lip6.fr/pub/math/sagemath/src/sage-9.2.tar.gz
tar xvf sage-9.2.tar.gz
cd sage-9.2
./configure
make

And now, let's wait…

Portage

After a long, long, long time waiting I remembered that there existed a Gentoo overlay for Sage. And in the meantime I thought I'd try that solution instead since some good Gentoo people already did most of the effort.

Just a few files to edit…

Now - let's build Sage with Portage!

>>> Emerging (1 of 100) sci-mathematics/cliquer–1.21::gentoo

At least I know more or less how long I'm going to wait and know what exactly fails to build, if anything does.

Final

Build

$ qlop -tv sage

Git stats

Overlays

This info we can easily gather with executing:

1	emerge --info

Gentoo' HEAD: 33f2d770c28307b1e9a1199c681e1c543602c6d4

Sage-on-Gentoo's HEAD: f7eac5b7e1a844132164b7593dab85cd87918664

Sage

Sage repository's HEAD (because we are using the live (9999) ebuild):

1	cat /var/cache/distfiles/git3-src/sagemath_sage.git/refs/heads/develop

Which returns: 5cb72aade9b297c10bb0f1ae8529466e5b5eb41d
