Re: Using DDD with an arm-elf-gdb

[Cal Erickson]

All,
We do this all the time with DDD. We have ddd on the host computer and
use cross built gdb for several different targets connecting through
gdbserver. We did not do anything except build ddd for the host (RedHat,
SuSE Mandrake and Solaris). As long as you specify the inferior debugger
it just works.
