Compile HelloWorldWidget using MXMLC?

Question

I am trying to compile the Flex Viewer 2.0 "HelloWorldWidget" using MXMLC in the SDK.  I am getting the following error messages:

\com\esri\viewer\IBaseWidget.as(94): col: 28 Error: Type was not found or was not a compile-time constant: Map.

function set map(value:Map):void;

\com\esri\viewer\IBaseWidget.as(95): col: 24 Error: Type was not found or was not a compile-time constant: Map.

function get map():Map;

I managed to compile and deploy few Flex API 2.0 sample applications but can???t port these applications to widgets.

Your help is highly appreciated!

I managed to compile "HelloWorldWidget" using MXMLC command line only.  This thread can be closed now.

A widget should be compiled as a module and optimized for �??index.mxml.�?� Use the following command line to generate a �??link report�?� and unload links from the widget.

[INDENT]1.Generate the linker report and compile the application: 
[INDENT]mxmlc -link-report=report.xml MyApplication.mxml[/INDENT]
2.Compile the module and pass the linker report to the load-externs option: 
[INDENT]mxmlc -load-externs=report.xml MyModule.mxml[/INDENT][/INDENT]
Replace the ESRI �??index.swf�?� with your homebrew �??index.swf�?� and replace
the �??HelloWorldWidget.swf�?� as well.   Your �??HelloWorldWidget�?� should be ready for testing at this point.

I have attached my command line and local config files.   Hopefully, my post can be useful to other developers.

As for Flex Viewer 2 documentation:
The Flex Viewer now has an online presence at http://help.arcgis.com/en/webapps/flexviewer/ and so the documentation is no longer part of the download.  For developers, the content is admittedly thin for the beta, but http://help.arcgis.com/en/webapps/flexviewer/help/index.html#developers/gettingstarted_dev.htm is still a good starting point for Flex developers using the ArcGIS Viewer for Flex 2.

Thank you Odoe,

I am using MXMLC coomand line only.  I use a local config xml to link agslib-2.0-2010-06-25.swc.  My SWF applications work OK.  However, I can't use this approach to compile a widget.

One thing I observed was that the ESRI "HelloWorldWidget" SWF is 68K.  The same widget the I compiled from the source code is 364K.  Actually, all my SWF applications are about the same size.  I figure it out that it might have something to do with agslib-2.0-2010-06-25.swc.  I took out the local config xml, now MXMLC is stuck at IBaseWidget.as.

I recalled that there was a flexviewer-1.0.swc in the old SFV.  I can't find the flexviewer swc , nor the developer's guide, in the 2.0 distribution package.

Your help is hightly appreciated.
