Installing LDC on Gentoo

There is a Gentoo portage overlay for the LDC compiler officially supported by the developers. You can add the overlay with layman. If you do not have layman yet then install it with

emerge -av layman

After that you have to add to /etc/portage/make.conf the following line:

source "/var/lib/layman/make.conf"

To use the LDC overlay, simply add our URL to /etc/layman/layman.cfg:

overlays  : http://www.gentoo.org/proj/en/overlays/repositories.xml
            https://raw.github.com/ldc-developers/gentoo-overlay/master/overlays.xml

Then update the overlay list

layman -L

and add the LDC overlay:

layman -a ldc

To emerge LDC you simply type:

emerge -av ldc2

Currently the LDC packages are marked as unstable. If you do not accept unstable packages globally then you have to add to /etc/portage/package.keywords the entry

dev-lang/ldc2 **
