Setting compiler.theme option for Halo/Flex 4 in FlashDevelop

Question

Here's what works with ant build.xml:

    <mxmlc file="${module.main.dir}/main.mxml" keep-generated-actionscript="false" output="${module.output.dir}/main.swf" fork="${flex.fork}">
        <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/>
        <source-path path-element="${FLEX_HOME}/frameworks"/>
        <compiler.theme file="${FLEX_HOME}/frameworks/themes/Halo/halo.swc"/>
    </mxmlc>

I tried the following values in Project > Properties > Compiler Options > Additional Compiler Options but none of them worked:

-theme=PATH_TO/halo.swc
-compiler.theme=PATH_TO/halo.swc
-theme=file=PATH_TO/halo.swc
-compiler.theme.file=PATH_TO/halo.swc
-theme.file=PATH_TO/halo.swc

Thanks.

Answer 1

-compatibility-version=3 should fix it

or you could try

-theme=../frameworks/themes/Halo/halo.swc

Answer 2
