There are several ways to compile GMAT. Two approaches are based on Microsoft Windows Visual Studio 2010 Express. A CMake system is currently under development.
Primary Build System
The primary GMAT build system is based on Visual Studio 2010 on Windows and GCC on Mac and Linux. The Windows documentation is currently written in LaTeX and is stored in our SourceForge repository. There is no current Linux documentation, but the procedure is very similar to the Mac instructions.
Alternative Build System
GMAT can be configured and compiled using CMake. However, these build scripts are still under construction. Here is documentation on the CMake system.
Using the GSFC-Internal CMake Build System
Here are instructions about using the updated CMake-based build system (currently GSFC-internal)
How to Build Scripts on Windows 7/8, Linux Ubuntu 12.04 and Macintosh OSX Lion systems
Here are instructions about Building GMAT on Windows, Linux and Macintosh systems.
How to Use the Build System
Here are instructions for advanced users about how to use the Build System.
Static Debug Build System
GMAT has a simple static build Solution for Microsoft Windows Visual Studio 2010 Express. This is not well documented but it is often used by developers for debugging.
