compiler options for release build

[josh_on]

I am using Ant to build a series of swfs in an Actionscript project and I want to compile them as small as possible, but I can't compile them as small using Ant and the mxml compiler as I can compiling in FB using the Release Build.  What options can I use to emulate the FB release compilation?

I use optimize=”true” and debug=”false”

I have also seen this asked here:

On: http://flex.gunua.com/?p=79 Chris asked:

Does anybody know why the swf file is bigger when compiled by Ant, as opposed to when it’s done by the Flex Builder. It is even smaller (1/2 the size) when I use the “Export Release Build” option.
I am using optimize=”true” and debug=”false” in the mxml task, but it does not seem to be enough.

Hi Josh,

I think this should help. The -dump-config option should help you get what you want.

Thanks Nishad,

I only just saw this now - but it is still useful - I hadn't thought of doing that.

At first glance it was a little disappointing - I didn't see much of interest except:

<!-- compiler.omit-trace-statements: toggle whether trace statements are omitted-->

<omit-trace-statements>true</omit-trace-statements>
