Get the code

Follow the instructions on the Downloads page to check out a copy of the GMAT source code from SourceForge.

Optionally, you can also check out a copy of the plugins repository further down on that page. If you choose to get the plugins code, you only need to check out the trunk/code directory from the repository. The rest is associated testing and documentation code, and is quite large.

We'll refer to the SourceForge checkout as sf and the internal code checkout as plugins.

Toolchain

You'll need the standard GNU toolchain, including GCC and make.

wxWidgets

GMAT needs a version of wxWidgets with OpenGL enabled and Unicode disabled. This usually means building a custom wxGTK library:

1. Download wxGTK 2.8.12 from http://wxwidgets.org.
2. Unzip and untar the downloaded file.
3. In a Terminal, run the following commands from the new wxGTK-2.8.12 directory (replacing /path/to/wxGTK-2.8.12 with the absolute path to your wxGTK-2.8.12 directory): 
   chmod a+x ./configure
   
   mkdir build-gmat
cd build-gmat

...

1. ../configure

...

1. --prefix=/path/to/

...

1. wxGTK-2.8.12/build-gmat --with-opengl
2. Run make to compile the

...

1. wxGTK libraries:
   
   make
2. Run make install to install the libraries and correctly set install paths. This is necessary due to bug GMT-3021.
   
   make install

2. Copy sf/trunk/build/macosx/BuildEnv.mk to sf/src
3. Edit BuildEnv.mk to set the following variables:

Configure the bundled plugins

The public GMAT repository (on SourceForge) includes several plugins that can be compiled along with the main application.

MatlabInterfacePlugin

The MatlabInterfacePlugin is available on OS X Leopard (10.5) and Snow Leopard (10.6) only.

1. Copy sf/plugins/MatlabInterfacePlugin/build/mac_snowleopard/MatlabInterfaceEnv.mk (or mac_leopard) to sf/plugins/MatlabInterfacePlugin/src.
2. Edit the new sf/plugins/MatlabInterfacePlugin/src/MatlabInterfaceEnv.mk file:
   WX_INSTALLED: path to the directory containing wx-config; usually this is the wxMac-2.8.12 directory
   MATLAB_DIR: path to a MATLAB app (such as /Applications/MATLAB_R2012a.app)

Plugin configuration: To use the MATLAB interface plugin, you must have the following environment variable configured:
MATLABFORGMAT=/path/to/MATLAB_ver.app
You can do this system-wide by putting the variable and its value into the file ~/.MacOSX/environment.plist using the OS X Property List Editor. See Apple QA1067 for details. You'll need to log off and log back on before the setting will take effect.

CInterfacePlugin (alpha)

Copy sf/plugins/CInterfacePlugin/build/macosx/CInterfaceEnv.mk to sf/plugins/CInterfacePlugin/src. No extra configuration of this file is necessary.

   SPICE_DIR: path to the directory containing cspice

EstimationPlugin (alpha)

Copy sf/plugins/EstimationPlugin/build/macosx/OdEnv.mk to sf/plugins/EstimationPlugin/src. No extra configuration of this file is necessary.

EventLocatorPlugin (alpha)

Build GMAT and plugins

1. Change to the top-level sf directory
2. Run make
