By default, dbx looks in the directory in which the program was compiled for the source files associated with the program being debugged. If the source or object files are not there or the machine you are using does not use the same path name, you must inform dbx of their location.
If you move the source or object files, you can add their new location to the search path. The pathmap command creates a mapping from your current view of the file system to the name in the executable image. The mapping is applied to source paths and object file paths.
Add common pathmaps to your .dbxrc file.
(dbx) pathmap [ -c ] from to
If -c is used, the mapping is applied to the current working directory as well.
The pathmap command is useful for dealing with automounted and explicit NFS-mounted file systems with different base paths on differing hosts. Use -c when you try to correct problems due to the automounter because current working directories are inaccurate on automounted file systems.
The mapping of /tmp_mnt to / exists by default.
