Chapter 2: Running dbx

Compiling and Linking Programs With Dynamic Shared Objects

This section summarizes a few things you need to know if you compile and

link your program with Dynamic Shared Objects (DSOs). A DSO is a

relocatable shared library. By linking with a DSO, you keep your program

size small and use memory efﬁciently.

If you compile and link with DSOs, dbx automatically notices their use in the

program and picks up the relevant debugging information. The dbx

command listobj shows any DSOs in a process. The dbx command whichobj

lists all DSOs in which the named variable is present.

See “Running Your Program” on page 9 for more description of the

differences between programs compiled and linked with DSOs and

programs compiled and linked with non-shared libraries. See also the dbx

help section on hint_dso for more information on dbx and DSOs. For more

information on DSOs, see “Using Dynamic Shared Objects” in the Compiling

and Performance Tuning Guide.
