I'm remote debugging a qt application from one ubuntu machine to another ubuntu one. I can do it from the console with:

root@eclipsePC# sudo ssh apppcIP -X
root@appPC# export DISPLAY=:0.0
root@appPC# gdb myApplication

Now I'm trying to do the same with Eclipse cdt (starting eclipse with sudo). I've defined the remote connection as a Linux type system. It works for application with no graphics, but for my qt application I get:

Listening on port 2345 Remote debugging from host "myEclipseIP"

myApp: cannot connect to X server

Child exited with status 1

GDBserver exiting logout

I've tried doing

root@appPC# xhost +
root@appPC# export DISPLAY=:ECLIPSEPCIP:0.0

but it didn't work. Anyone knows how to do this? Thanks

I've added the argument -display ECLIPSEPCIP:0.0 in the debug config and now it starts, but in the appPC instead of the host ECLIPSEPC.
