Getting the FreeSpace2: SCP Source Code

Note: In April 2015, the SCP team transitioned the source code repository from SVN-based to GitHub-based (Git).

Windows

Warning: The Windows section has yet to be updated for the transition to GitHub.

Ported from karajorma's thread on the HLP Forums.

Here's how you set things up:

Go to the Tortoise SVN homepage and download the latest version.
Install it. You'll probably have to restart your PC afterwards.
Make a new folder on your HD where you'd like to install the code. You'll need a fair bit of space for the code + the intermediate files when building it. Press right mouse and choose SVN Checkout from the list.

An new window will open up. Cut and paste this into the URL of repository box:
svn://svn.icculus.org/fs2open/trunk/fs2_open
By default the HEAD revision will be selected. You probably don't want to change this. Your screen should now look like this:

It's pretty easy. It shouldn't take you more than a minute or two to do once you've installed Tortoise.
