Description Matt Heitz CLA 2011-06-03 12:04:18 EDT 
I have the latest build, 0.7.0 N201106031036.  I'm using a new workspace.  The EGL builder fails with the problem shown below on a simple Hello World program.  Look for "Caused by" in the stack trace.


package p;

program Hello
	function main()
		writeStdout( "Hello world" );
	end
end

Comment 1 Justin Spadea CLA 2011-06-03 15:59:10 EDT 
The problem was due to edt.compiler shipping as a jar instead of a directory. edt.compiler is now a directory in installations, and if we move the eglars we can change it back to a jar (or we can update the code to be able to look inside jars).

Thanks, it's working now.
