On March 2008, the SCP team has changed the repository server from CVS based to SVN based.

Some terms have also changed with the new repository server:

  • The stable branch (old CVS) is now called Trunk (new SVN).
  • HEAD revision (new SVN) is latest version. Do not confuse it with the unstable branch, also called HEAD branch, in old CVS.


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:
  • By default the HEAD revision will be selected. You probably don't want to change this. Your screen should now look like this:


  • Press OK to begin downloading from the repository.

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


Please see the Mac Development Guide.


With a fresh Ubuntu 12.10 (latest) install, you will need to install the following packages. Other distributions will vary on which packages need to be installed on top of the base install.

  • build-essential
  • subversion
  • autoconf
  • automake
  • libsdl1.2-dev
  • libogg-dev
  • libvorbis-dev
  • libtheora-dev
  • lua5.1
  • liblua5.1-0-dev
  • libjpeg-dev

To checkout the fs2_open repsoitory :

svn checkout svn://

After checkout, autogen the makefiles

cd fs2_open

To build a debug build :

cd fs2_open
./ --enable-debug

To build with custom CFLAGS :

cd fs2_open
./ "CFLAGS={Your CFLAGS Here}"

Note that the quotes are required

Building with custom CFLAGS for machine specific binaries (such as -march=native -mtune=native), may be unstable and unsupported. Use at your own risk.

After makefile autogen is complete, run 'make' to actually build the executable. Use the -j option to compile faster. It causes make to use multiple cores instead of 1.

make -j 4

The number after '-j' should be the number of logical processors (physical + hyperthread)

After compiling completes, the executable is placed at $(FSO_BUILD_DIR)/code/fs2_open.M.m.vv (currently 3.6.19)

Copy this file to your fs2_open installation directory (your path will vary). You may need root permission to copy the file.

sudo cp ./code/fs2_open_3.6.19 /usr/share/games/freespace2
