Gentoo Linux HOWTO

If you use Gentoo, then things seems to be very easy ;)

Clone the repo:

git clone git@github.com:usrbinnc/netcat-cpi-kernel-module.git

Emerge vorbis-tools. Make sure you have ogg123 USE flag enabled (its default so, probably its already enabled).

sudo emerge -av vorbis-tools
These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] media-sound/vorbis-tools-1.4.0  USE="nls ogg123 -flac -kate -speex" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB

Go inside project repo and, make it!

cd netcat-cpi-kernel-module
make

Load the newly created module

sudo insmod netcat.ko

And finally enjoy the music :D

aline@luiza-mouraria ~/Projects/netcat-cpi-kernel-module $ ogg123 - < /dev/netcat
