12.2 Specifying shared library locations
On HP-UX, when the shared libraries your program uses are in a different directory than
the path specified in the source or object files, specify the correct files to use with one
of two environment variables.
`GDB_SHLIB_PATH' Set this variable to a colon-separated list of directory path
names where the desired shared libraries reside. GDB searches
specified list of directories for shared libraries before searching
the default system directories.
`GDB_SHLIB_ROOT' Set this variable to point to the root of the library in which the
desired libraries reside.
NOTE: If you set both the `GDB_SHLIB_PATH' and `GDB_SHLIB_ROOT' environment
variables, the `GDB_SHLIB_PATH' behavior overrides `GDB_SHLIB_ROOT'.
These environment variables are useful when you are analyzing core files on a system
other than the one that produced the core file.
For example, if you want GDB to search for libraries in /home/debugger/lib and
/tmp/lib before searching the default system directories for libraries, you can use this
setting:
GDB_SHLIB_PATH=/home/debugger/lib:/tmp/lib
With this setting, GDB searches the directories in the order specified until it finds a library
with the correct name.
In this example, if GDB encounters a library by the name of /usr/lib/libsubs.sl,
GDB searches first for /home/debugger/lib/libsubs.sl and then for /tmp/lib/
libsubs.sl. If neither of these exists, then GDB searches the default system directories
and finds /usr/lib/libsubs.sl.
In most cases, GDB_SHLIB_PATH allows more flexibility than GDB_SHLIB_ROOT'
because it allows you to specify more than one path. However, there are some cases in
which you may want to choose to use GDB_SHLIB_ROOT.
For example, if you have more than one shared library with the same name but different
path names, you may want to use GDB_SHLIB_ROOT because GDB searches for libraries
based on the full path name.
Note that GDB_SHLIB_PATH may not give you the results you expect because GDB
searches for libraries that match only the name, regardless of the path, and always
accepts the first library that matches the name.
For example, if you want to use /tmp/usr/lib/libsubs.sl and /tmp/usr/share/
lib/libsubs.sl, you can set GDB_SHLIB_ROOT' to /tmp. Now whenever GDB
encounters a library with the name /usr/lib/libsubs.sl and /usr/share/lib/
