Compiling components with Flex 2 SDK

Distributing a component as a SWC file

To create a SWC file, use the compc utility in the flex_install_dir/bin directory. The compc 
utility generates a SWC file from MXML component source files and/or ActionScript 
component source files. 

In this example, you create a SWC file for a custom formatter component that you defined by 
using the following package and class definition:

package myComponents.formatters
{

//Import base Formatter class.
import mx.formatters.Formatter

public class MySimpleFormatter extends Formatter {

...

}

}

In this example, the MySimpleFormatter.as file is in the directory 
c:\flex\myComponentsForSWCs\myComponents\formatters. 

You use the following compc command from the flex_install_dir/bin directory to create the 
SWC file for this component:

.\compc -source-path c:\flex\myComponentsForSWCs\ 

-include-components myComponents.formatters.MySimpleFormatter 
-o c:\flex\mainApp\MyFormatterSWC.swc

In this example, you use the following options of the compc compiler:

In your main application file, you specify the component’s namespace, as the following 
example shows:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" 

xmlns:MyComp="myComponents.formatters.*">

Option name

Description

-source-path

Specifies the base directory location of the MySimpleFormatter.as 
file. It does not include the directories that the component’s 
package statement defines.

-include-components

Specifies the component to add to the SWC file, and includes the 
information that the package statement specifies. 

-o 

Specifies the name and directory location of the output SWC file. In 
this example, the directory is c:\flex\mainApp, the directory that 
contains your main application.
