The debugger can run on the same platform as the executable being debugged:
Figure 1. Debugging in a self-hosted environment.In this case, the debugger communicates directly with the program you're debugging. You can choose this type of debugging by running the target procfs command in the debugger — or by not running the target command at all.
Note:
It's also possible to use the target qnx command so that
the debugger communicates with a local program via a debug agent, but
this is the same as debugging in a cross-development environment.
A procfs session is possible only when the debugger and the program are on the same QNX Neutrino system.
