Before starting GDB, ensure that:
RDBC is running on the target (for standard application debugging). If RDBC is not running, run it without any argument.
RDBD is running on the host (for process dump analysis).
The name of the GDB executable differs according to the target platform and takes the form target-type-chorusos-gdb. Thus, depending on the platform, type one of the following to start GDB:
$ sparc-chorusos-gdb --nw
$ powerpc-chorusos-gdb --nw
$ i386-chorusos-gdb --nw
By default, the Insight GUI is started when you start GDB. To start GDB without the Insight GUI, you must include the --nw option.
