Compiling AS2.0 Projects with mx.* dependencies in FlashDevelop Beta 3 August 9, 2007

FlashDevelop Beta3 comes bundled with MTASC, but it by default misses an important configuration option, so building projects with references to mx.* will complain, even with the -mx option set, like:

characters 8-25 : type error class not found : mx.controls.Button

You'll need to add the following to the classpath (preferably global):

C:\Program Files\Adobe\Adobe Flash CS3\en\First Run\Classes

One trick to editing it in FlashDevelop since the file selector doesn't allow you to paste it in directly, opening up a windows Explorer window while the file dialog is open, and pasting the above into the address bar, a neat trick of windows is all windows are listening to the same events, so it will take the FlashDevelop tree browser to the correct spot.
