Before starting Insight, make sure 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 Insight 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 Insight:
$ sparc-chorusos-gdb
$ powerpc-chorusos-gdb
$ i386-chorusos-gdb
By default, the Insight GUI is started when you start GDB. The main window of the Insight GUI is shown in Figure 2-2.
