Re: Initializing the menubar

Okay... I've got a menu to show up, but the behavior seems to depend 
on the location of the executable file, which I don't understand.

If I put the code below in a file called "cocoa.m" and compile it 
from the command line with:

    gcc -o cocoa cocoa.m -framework Cocoa

and I run it like this:

    ./cocoa

then no menu shows up.  But if I copy the binary into a bundle 
directory, like this:

    cp cocoa CocoaTest.app/Contents/MacOS/CocoaTest

and run that same binary, at the different location:

    ./CocoaTest.app/Contents/MacOS/CocoaTest

then the menu bar shows up.

Why the difference?  Does a cocoa binary have to run from within a 
bundle directory?

thanks,
Rob
