You need to tell ddd what type of inferior debugger you are using. For 
instance if you were using a cross gdb that was targeted for Xscale
then you would do something like:

ddd --debugger xscale_le-gdb --gdb hello.exe

This way ddd knows what the protocol looks like to communicate to the
inferior debugger. The inferior debuggers that ddd knows about are gdb, 
dbx, xdb, jdb, pydb and perl. There are other options you can use and 
they are all documented in the ddd manual.
