Accessing Git repository
From LMMS Wiki
Assuming you have git installed, you first have to get a copy of the Git repository:
git clone git://lmms.git.sourceforge.net/gitroot/lmms/lmms
If you want to have the latest unstable developer version you're already done. For getting the latest stable version, do the following:
cd lmms git checkout -b stable-0.4 origin/stable-0.4
Afterwards you have a directory lmms in your current directory which contains a complete source-directory. Before you continue, make sure you've cmake installed! Then type:
cd lmms cmake .
(note the dot after command, it tells cmake to operate on current directory)
Now you can configure and build LMMS the usual way or see Installation tutorial for details on how to proceed.
If you want to update your copy simply type
git remote update git pull
inside lmms-directory. The first step usually can be omitted.
Git with your SF.net-account
Of course you can use your SF.net-account for cloning the repo and work on it. If you're a registered developer of LMMS, you'll also be able to commit your changes.
git clone ssh://YOUR_SF_NET_NICK@lmms.git.sourceforge.net/gitroot/lmms/lmms
Browse Git code
For browsing the Git repository easily you can also use the Git Web interface.
