If you prefer the latest development code, wish to contribute to GNU Radio, or want to work with features that haven't yet made it into the stable branch, you can check out the source from the git repository using one of these two lines:

$ git clone git://
or (and this is the preferred method if your git client is version 1.6.6 or greater)
$ git clone

You can also pull our mirror from github:

$ git clone git://

if you plan to merge your changes back into the gnuradio tree.

Later, to update your local repository you can run:

$ git pull

The development code comes in three flavours: master, maint and next (these are in fact the names of the git branches). master is the main branch, which will be the next stable release. next is where all the crazy stuff is happening, the most bleeding edge code out there. maint is a maintenance branch of the most current release, i.e. the latest stable release plus bugfixes.

If you're using the git cloned code, you can switch between these three branches by going to your git-cloned repository and issuing the 'git checkout' command with the branch name desired, like this:

$ git checkout maint

Even more bleeding-edge development code (Katana-edge)

The next branch is too stale for your taste? Some of the developers have exposed their development repositories. If you want to check these out, we're assuming you know what you're doing, so no more explanations:
