Troubleshooting Tips
Debugging executables over NFS
You can debug executables that are stored on NFS-mounted file systems. However, you cannot
attach to an existing process if the executable you are running resides on an NFS-mounted
file system instead of on your local machine’s file system. To work around this problem, copy
the executable onto your local machine’s file system, restart the process on your local
machine, run the debugger, and attach to the process.
Attaching to a process with shared libraries
If you want to attach to a running process that contains shared libraries, before you run your
program, you need to run the command /usr/bin/pxdb -s enable executable_file where
executable_file is the name of your program executable.
Double-Clicking with ReflectionX
If you are running the WDB GUI using ReflectionX, the default double-click parameters may
be too sensitive to work properly. You can increase the double-click time by setting the
following X resource:
Wdb*multiClickTime: 600
For information on setting X resources, refer to the xrdb(1) man page or to the RESOURCES
section of the x(1) man page.
Setting breakpoints that never appear in the breakpoints list
You may set a breakpoint that does not show up in the breakpoints list. This may be caused
by:
• The breakpoint has been deferred. See Working with Deferred Breakpoints.
• Or a breakpoint was actually set as you specified, however the debugger cannot locate the
appropriate file using the current source file paths that you have set. To update the source
file paths, see Setting Source Paths.
