Comedi is the kernel-level driver code. Comedilib is the user-level API library code.

The recommended way to install the Comedi kernel modules from comedi.org is to compile from the current Git source, as the released versions are quite old (in particular, comedi-0.7.76 only supports kernels up to 2.6.24).

Kernel versions 2.6.30 onwards have an experimental in-tree Comedi implementation in the driver "staging" area. This support should improve with later kernel versions. Note that RTAI support for the in-tree "staging" version is still in development, so for current RTAI releases the Git version of Comedi should be used.

The latest unstable version of Comedi and Comedilib can be checked out using Git, using the commands:

git clone https://github.com/Linux-Comedi/comedi.git
git clone https://github.com/Linux-Comedi/comedilib.git

You may also want comedi_calibrate or comedi-nonfree-firmware:

git clone https://github.com/Linux-Comedi/comedi_calibrate.git
git clone https://github.com/Linux-Comedi/comedi-nonfree-firmware.git

The Git repositories were previously hosted on comedi.org and had URLs of the form "git://comedi.org/git/comedi/repository.git". To update the URLs of previously cloned repositories (from comedi.org) to use the current github.com URLs, use the "git remote set-url" command as follows:

cd /path/to/comedi
git remote set-url origin https://github.com/Linux-Comedi/comedi.git

cd /path/to/comedilib
git remote set-url origin https://github.com/Linux-Comedi/comedilib.git

cd /path/to/comedi_calibrate
git remote set-url origin https://github.com/Linux-Comedi/comedi_calibrate.git

cd /path/to/comedi-nonfree-firmware
git remote set-url origin https://github.com/Linux-Comedi/comedi-nonfree-firmware.git

(Adjust the above commands according to which of the repositories you have previously cloned, and their local filesystem pathnames.)
