0. Login as root or use sudo.
1. Install layman to manage overlays if don't have this tool already.
sudo emerge -v app-portage/layman
2. Add brancik-overlay.xml file to the /etc/layman/overlays directory with the following content:
sudo nano -w /etc/layman/overlays/brancik-overlay.xml
brancik-overlay Ctibor Brancik's overlay http://git.brancik.cz firstname.lastname@example.orgCtibor Brančík
Or you can use layman-overlay-maker tool if you have >=app-portage/layman-2.0.0.
More info about Gentoo overlays and their management can be found on Gentoo wiki.
3. Add overlay:
sudo layman -f -a brancik-overlay
4. To install all available indilib drivers simply use provided portage set:
sudo emerge -v @indilib-drivers
5. If you want to install only drivers for the devices you use (as is the Gentoo way), you have to set appropriate USE flags:
Available USE flags (note that only 3rd party drivers are present, with exception of indi-qhy-old. All other drivers are installed by sci-libs/indilib itself):
aagcloudwatcher apogee asicam duino eqmod fishcamp fli gphoto2 maxdomeii meadedsi qhy qsi sbig spectracyber sx tess
nano -w /etc/portage/package.use/indilib #Enable drivers USE flag which pulls sci-libs/indilib-drivers as dependency sci-libs/indilib drivers # To install indi_gphoto_ccd, indi_qhy_ccd and indi_sbig_ccd. # sci-libs/indilib-drivers is a meta ebuild and works similar to x11-base/xorg-drivers package. sci-libs/indilib-drivers gphoto2 qhy sbig sudo emerge sci-libs/indilib::brancik-overlay
6. Note that ebuilds for stable release of indilib drivers (currently 1.0.0) are keyworded unstable (~amd64, ~x86 specifically) and live source ebuilds are all masked by package.mask. You will have to unmask them during installation (use emerge with --autounmask-write option). See official docs if you do not know this means exactly.
