As per the current Portage specification, ebuild repositories (a.k.a. overlays) can be managed via file collections under /etc/portage/repos.conf/, via the new plug-in sync system.
The overlay can be enabled via the repository extension of the Gentoo eselect utility.
emerge --ask --noreplace --verbose eselect-repository eselect repository enable scienceEselect-repository Uninstall
To disable and remove the overlay, run:
eselect repository disable science eselect repository remove science
To enable the overlay without the need for dedicated repository software, you need to have git installed:
emerge --ask --noreplace --verbose dev-vcs/git
Then you can simply download the science repository configuration file, science.conf:
wget https://gitweb.gentoo.org/proj/sci.git/plain/metadata/science.conf \ -O /etc/portage/repos.conf/science
To disable and remove the overlay, run:
rm /etc/portage/repos.conf/science rm /var/db/repos/science -rf
You can also install the overlay via the layman overlay manager.
emerge --ask --noreplace --verbose app-portage/layman layman --add science
To delete the overlay, run:
Using Packages from::science
To start using the overlay you now only need to get the newest files, via:
To be able to install ::science packages you need to make sure that you are accepting the ~${ARCH} keyword for your respective architecture. This may already be the case globally on your system, and you can check whether this is the case by running:
grep "~$(portageq envvar ARCH)" /etc/portage/make.conf
If the above returns empty, you will need to instruct Portage to accept ~${ARCH} packages.
This can be done for ::science specifically:
mkdir -p /etc/portage/package.accept_keywords printf '*/*::science ~%s' "$(portageq envvar ARCH)" >> /etc/portage/package.accept_keywords/science
If the above fails with mkdir: cannot create directory ‘/etc/portage/package.accept_keywords’: File exists this means you are using a file and not a directory, and you can instead run:
printf '*/*::science ~%s' "$(portageq envvar ARCH)" >> /etc/portage/package.accept_keywords
Alternatively, and only if you know what you are doing, you can accept ~${ARCH} packages globally:
printf 'ACCEPT_KEYWORDS="~%s"' "$(portageq envvar ARCH)" >> /etc/portage/make.conf
The downside of this approach is potentially higher instability, the advantage is that often ::science packages require ~${ARCH} packages from ::gentoo as well.
If you fork, we will merge!
We welcome new contributors and are happy to include new packages.
For a brief introduction please see our contributing guide. Further helpful resources are:
Additionally, please make sure to add the Science Project as an additional maintainer to any new packages you submit. For an example, take a look at the metadata for the Numba package - dev-python/numba/metadata.xml
You can ask for help on Libera IRC in #gentoo-science. Alternatively you can report bugs on the Gentoo Bugzilla.
