FreeSpace2 Source Code Project

Building

For building you will need CMake. Version 3.4 is required. Once you have installed CMake you should create a build directory where the project/make files should be created, do not create them inside the source tree!

On Windows you can use the cmake-gui executable to get a nice GUI, on Unix just use cmake. Use the newly created directory as build directory (change to this directory on Unix) and run cmake. On Windows this can be done by clicking the Configure button. Choose your compiler version and hit Generate when configuring is done.
Depending on the makefile generator used build the all or ALL_BUILD target to compile the project.

Available variables to control the build

  • FSO_BUILD_WXFRED2: Build the wxfred2 project, requires wxWidgets
  • FSO_FREESPACE_PATH: Sets the path of your FreeSpace install, can be used to automatically run the generated executables with the correct working directory, this is an optional variable. By default this will use the value of the FS2PATH environment variable.
  • FSO_BUILD_TOOLS: Build some tools related to FSO

Windows only variables

  • FSO_BUILD_FRED2: Build FRED2, requires a Visual Studio version that ships with MFC
  • FSO_USE_SPEECH: Build a binary with text-to-speech support
  • FSO_USE_VOICEREC: Build a binary with voice recognition support

Advanced variables

You should only use these variables if you know what you're doing

  • FSO_CMAKE_DEBUG: Print CMake debugging informations
  • FSO_BUILD_INCLUDED_LIBS: Build libraries from the included source
  • FSO_USE_OPENALSOFT: Use OpenALSoft for OpenAL support
  • FSO_USE_LUAJIT: Use luajit as a replacement for lua
  • FSO_DEVELOPMENT_MODE: Toggles some development behavior, only use if you really need it.
  • FSO_RUN_ARGUMENTS: If you run an executable from within the project, these arguments will also be passed to the executable
  • FSO_BUILD_POSTFIX: Sets a postfix to be added to the executable name, may be useful for release candidates.

Visual Studio specific variables

  • MSVC_USE_RUNTIME_DLL: Use the DLL version of the runtime, experimental and not well tested.
  • MSVC_SIMD_INSTRUCTIONS: The instruction set the executables will be optimized for.

Generating an installation package

CMake can automaticall generate installation packages of the project. To do this you will just need to run the package target of the build system and the package will be placed inside your build directory. On Windows you will have to install NSIS to use this.
