Retrieving the source
The project repository is currently hosted on gitorious.org. In order to check out the code you will need to have a git client installed. Alternatively you can also download the source as a tar.gz.
Create a target folder for the branch:
mkdir python_nodes cd python_nodes
Using Git Client
Now clone the git branch (git clone is the equivalent of svn checkout). We're only cloning the node groups branch itself here, the repository contains a bunch of other branches, including the regular svn trunk in master branch:
git clone git://gitorious.org/~lukastoenne/blenderprojects/blender-lukastoenne.git -b custom_nodes blender cd blender
Download as tarball
Go to
https://www.gitorious.org/~lukastoenne/blenderprojects/blender-lukastoenne/commits/custom_nodes
On the right side you will find a button labeled Download custom_nodes as tar.gz. Click to generate a tar.gz archive and download to the python_nodes folder created above and extract
Building
From this point on the build procedure is the same as for regular SVN trunk.
