Nape physics breaks the new compiler

After running into problems implementing the new compiler on our game, I eventually cornered the problem to the Nape Physics library we're using for one of our games, http://napephys.com/.  Nape is build with haxe (https://github.com/deltaluca/nape) and then we include their release swc in our game.

If you just reference their Vec2 class in a completely vanilla project,

package

{

    import flash.display.Sprite;

    import nape.geom.Vec2;

    public class Napey extends Sprite

    {

        public function Napey()

        {

            Vec2

        }

    }

}

The compiler breaks with the error message (if you do a release build with FlashBuilder) of

Error occurred while packaging the application:

Compilation failed while executing : compile-abc

Which, as far as I can tell, doesn't give any great hints as to where the actual problem is.

The project, and those temp files from the abc compilation are at https://www.dropbox.com/s/bd9eabtkfxl5l6p/Napey.zip.  Nape is kind of pivotal for our game, and to replace it with something else would require a huge amount of work and effort, so getting this fixed would be a big deal for us.

Has the new compiler been tested with building with haxe libraries and such?

Hi,

Thanks for reporting the issue. We have fixed this issue and it should be available in next pre-release build.

Thanks

Huge thanks, Govinda quick responses, and quick fix like that is crazy appreciated.

Is there any chance that the error reporting, or logging, when the compiler breaks could be improved also?  We have a big enough project, and trying to find what was going wrong where, was a long arduous task.  We had disabled all the ANEs, because we'd heard that might be a compiler breaker, then disabled all the compiler defines, but completely forgot about third-party swcs, and only caught Nape after trying nearly everything else.

I'm not sure exactly what the name of the fix would have been, so I'm just wondering, did this get into the 13 release that was just announced, http://forums.adobe.com/message/6282299#6282299, or no?

Unfortunately no. However, we plan to make another release in a couple of weeks time and that will contain the fix for Nape.

This seems all good and fixed with the early 14.0 release.  Thanks so much for looking into and fixing this issue.
