Apache Flex (Flex)
==================

    Apache Flex is an application framework for easily building Flash-based applications 
    for mobile devices, the browser and desktop.
    
    For detailed information about Apache Flex please visit 
    http://incubator.apache.org/flex/

    Apache Flex is a large project with many pieces.  The framework is implemented
    in Actionscript and the compiler is implemented in Java.

    Currently supported platforms include:

        Microsoft Windows
        Mac OS X
        Apple iOS
        Google Android
        RIM BlackBerry

    Apache Flex is the software evolution of the popular Adobe Flex SDK project.
    
    The community surrounding Flex is vast, diverse, distributed globally, and with all 
    levels of proficiency in software development. It is estimated that there are between 
    350,000 and 500,000 Flex developers worldwide. 

Getting the latest sources via Subversion
=========================================

    You can always checkout the latest source via subversion using the following
    command:

    svn co https://svn.apache.org/repos/asf/incubator/flex/trunk flex

    For further information visit http://incubator.apache.org/flex/source.html
    
Building Apache Flex 4.8
========================

    Apache Flex 4.8 is a parity release from Apache of Adobe Flex 4.6.
    
    Apache Flex is a large project. It requires some build tools which must be installed
    prior to building Flex and it depends on some external software which
    are downloaded as part of the build process.  See the Software Dependencies
    section for more information on the external software dependencies.
    
    From Apache's perspective, the Adobe Flash Player and Adobe AIR have excluded
    licenses so they can not be bundled with the Apache Flex binaries.  They must be
    installed prior to building Apache Flex.
    
Install Prerequisites
---------------------

    Adobe Flex 4.6 was certified with AIR 3.1 and Flash Player 11.1.  Adobe Flex 4.8
    will continue to use these.

    Before building Flex you must install the following software and set the
    corresponding environment variables using absolute file paths.  Relative file paths
    will result in build errors.
	
	The environment variables PLAYERGLOBAL_HOME, AIR_HOME, FLASHPLAYER_DEBUGGER,
	PIXELBENDER_HOME and ADOBE_EXTENSION_MANAGER can also be set in the property file 
	called env.properties. See the env-template.properties file for instructions.
    
    The Adobe Flash Player playerglobal.swc is needed to compile all the components
    with the exception of the airframework and airspark components which require
    airglobal.swc from the AIR Integration Kit.  The AIR Integration kit is also needed
    to build and debug mobile applications.  The Flash Player content debugger is
    used by checkintests and other pieces of the test subsystem to run compiled
    applications.  The Adobe Pixel Bender Toolkit is needed to build some
    files needed for effects.

        ErrorReportingEnable=1
        TraceOutputFileEnable=1
    
    and a FlashPlayerTrust file must allow local SWFs to access local files.

Using the Binary Distribution
-----------------------------

    You must download the thirdparty dependencies.

    When you have all the prerequisites in place and the environment variables set, 
    (see Install Prerequisites above), use

        cd <flex.dir>/frameworks
        ant thirdparty-downloads
    
Building the Framework in a Binary Distribution
-----------------------------------------------

    The source for most of the framework is included in the binary distribution.  
    It can be useful if you wish to debug and/or extend components.

    When you have all the prerequisites in place and the environment variables set, 
    (see Install Prerequisites above), use

        cd <flex.dir>/frameworks
        ant main        (or just ant since the default target is main)
    
    to download the thirdparty dependencies and build the Flex framework.  You may be 
    prompted to acknowledge some of the downloads.  Since the third-party dependencies 
    take a little while to download and they don't change very often, they are not 
    cleaned with the regular clean target.
    
    To clean the build, of everything other than the downloaded third-party dependencies 
    use
    
        ant clean 
    
    To clean the build, of everything, including the downloaded third-party dependencies 
    use
        
        ant super-clean (which is just thirdparty-clean followed by clean)

Building the Source in the Source Distribution
----------------------------------------------

    The source for both the Flex compiler and the Flex framework is included in the
    source distribution.  The compiler is in the modules directory and the framework
    is in the frameworks directory.
    
    When you have all the prerequisites in place and the environment variables set
    (see Install Prerequisites above), use

        cd <flex.dir>
        ant main        (or just ant since the default target is main)
    
    to download the thirdparty dependencies and build the source.  You may be prompted
    to acknowledge and/or confirm some of the downloads.  Since the third-party 
    dependencies take a little while to download and they don't change very often, they 
    are not cleaned with the regular clean target.
    
    To clean the build, of everything other than the downloaded third-party dependencies 
    use
    
        ant clean 
    
    To clean the build, of everything, including the downloaded third-party dependencies 
    use
        
        ant super-clean (which is just thirdparty-clean followed by clean)
        
    To generate a source distribution package and a binary distribution package use
        
        ant -Dbuild.number=<last svn rev> -Dbuild.noprompt=  release

    The packages can be found in the "out" subdirectory.
            
    To build the ASDoc package
        
        ant asdoc-package

    To get a brief listing of all the targets type
    
        ant -projecthelp


Thanks for using Apache Flex.
