Conditional Compilation in Flex (Actionscript) and Import Operations

I have a web application written in Flex and I am trying to create an AIR application from the same code base using conditional compilation.

In an AIR application, I need import statements, such as: import flash.data.SQLConnection; import flash.filesystem.File; but I cannot have these import statements in a web application because they are AIR classes.

I thought I could use conditional compilation to overcome this problem, but then I read the following at http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7abd.html : "You cannot use constant logical values to label metadata or import statements. "

If so, how can I have a common code base for Flex-based web applications as well as desktop applications? Has anyone solved this puzzle?

Thank,

Dilip

More on this subject after some testing and errors ... I have 3 projects in Eclipse for this project ... one for a web application, one for an AIR application and one for general source code. In the web and AIR project, I point to the common source code. In general code, I used conditional compilation, and it looks like you can do something like the following: CONFIG :: desktopMode {import flash.data.SQLConnection; import flash.events.SQLEvent; import flash.events.SQLErrorEvent; import flash.filesystem.File; }

and a similar approach for including web functions or individual AIR functions at compile time. This approach still works!

You can always switch to some kind of complete preprocessor, such as M4, and create your program using the usual build tools, and not with the IDE.
