Adobe AIR Development

Hi,

When trying to build a .bar with an Air native extension (ANE) file, I was getting the following error:

[Fatal Error] :1:1: Content is not allowed in prolog.
Error: Problem reading <ANE file path>: Content is not allowed in prolog.

where <ANE file path> is the relative path to my .ane file.

Turns out, the bar compiler (on OS X anyway) doesn't support an extensions.xml file that contains a Unicode byte order mark. In my case my xml file contained 3 bytes at the beginning marking it as a UTF-8 encoded file.

To remove the BOM, I opened the file in vim and:

:set nobomb
:wq

which re-saves the file without the BOM. Hope this helps someone.

Cheers,

Dave

Thanks Mark, will do.

I posted mainly so that there would be a search result for the next developer to stumble across this obscure issue .. I guess I didn't think of it as a bug in your tool so much as a bug in my process that allowed a BOM to get into the XML file (as many tools don't support them).

Cheers,

Dave
