php debugging

[steve]

Hi,

I saw that DDD 3.3.9 now supports PHP debugging.  I assume this is via
dbg.  My problem is that I can't figure out how to setup DDD to debug
PHP.  I tried Edit -> Preferences -> Startup, but the DBG button is
insensitive (I can't select it.)

Do I need to compile or configure with some --with-dbg option or
something?  (I actually tried that already.)  I'm all excited about
being able to attach to dbg with DDD - someone please help me do it!

Thanks,

Steve Stanners
