Building with Makefiles

There are two ways of building plug-ins on Mac OS X. You can either use Xcode or the Makefile that we supply with the devkit.

The Maya Development Kit product contains a number of example plug-ins located in /Applications/Autodesk/maya2009/devkit/plug-ins.

Before you can use these plug-ins, you need to build them. You first have to create a working directory, recursively copy the directory and run make. (The Maya install directory is not writable on this platform.) For example,

setenv MAYA_LOCATION /Applications/Autodesk/maya2009/Maya.app/Contents

mkdir -p $HOME/devkit

cd $HOME/devkit

cp -r /Applications/Autodesk/maya2009/devkit/plug-ins .

cd plug-ins

make Clean

make

Also, to attach your plug-in development area to the rest of Maya, you need to set a number of variables. These are:

• MAYA_LOCATION
• MAYA_SCRIPT_PATH
• MAYA_PLUG_IN_PATH
• XBMLANGPATH

These variables can be defined in a file called Maya.env. Maya lets you define these variables in a file so that you can easily set up the same runtime environment on another system by simply copying the file. You can still use variables in the environment and they will either override the corresponding variable in the Maya.env file or be prepended to the variable for variables which represent search paths.

The environment variable, MAYA_APP_DIR, can be used to help find the Maya.env file. If this variable is not set, Maya looks in your $HOME/maya directory. In addition, if you have multiple versions of Maya installed on your system, you can put your Maya.env file in a subdirectory of either the directory pointed to by the MAYA_APP_DIR environment variable or $HOME/maya.

Name the subdirectory to be the version number of the Maya application that is executed. For example, if you set MAYA_APP_DIR to be /usr/mydir, you can create a version specific Maya.env file in the directory /usr/mydir/2009. that will be used when the 2009 version of Maya is run. If you do not set MAYA_APP_DIR, you can put your version 2009 tailored Maya.env file in $HOME/maya/2009.

The following assumes that Maya is installed in /Applications/Autodesk/maya2009/devkit/plug-ins and that you have set up your plug-in development area in $HOME/devkit/plug-ins. If your installation is different, you will have to modify the lines that set MAYA_LOCATION in the examples below.

Your Maya.env file should contain the following:

MAYA_SCRIPT_PATH = $HOME/devkit/plug-ins

MAYA_PLUG_IN_PATH = $HOME/devkit/plug-ins

XBMLANGPATH = $HOME/devkit/plug-ins/

Either set the following on the command line or add the equivalent for the shell environment you are using. The following can be used placed into your .tcshrc if this is your default shell.

# Location of installed maya

setenv MAYA_LOCATION /Applications/Autodesk/maya2009/Maya.app/Contents

If you now start Maya and open the Plug-in Manager window, you should see a list of all the pre-compiled plug-ins you copied to your

$HOME/devkit/plug-ins directory. 

Building with Xcode 2.4.1 project files

To build one of our example plug-ins using the supplied Xcode 2.4.1 project file, you must use the version of Mac OS X 10.4 that Maya runs with and have the Xcode application installed. Then, do the following:

1. Browse to the /Applications/Autodesk/maya2009/devkit/plug-ins directory.
2. Make a copy of this directory and make it current.
3. Double-click on an Xcode project file such as circleNode.xcodeproj.
4. Select the Build option from the Build menu.
