Shared libraries are also supported in many cross or remote debugging
configurations. A copy of the target's libraries need to be present on the
host system; they need to be the same as the target libraries, although the
copies on the target can be stripped as long as the copies on the host are
not.
You need to tell @value{GDBN} where the target libraries are, so that it can
load the correct copies---otherwise, it may try to load the host's libraries.
@value{GDBN} has two variables to specify the search directories for target
libraries.
@table @code
@kindex set solib-absolute-prefix
@item set solib-absolute-prefix @var{path}
If this variable is set, @var{path} will be used as a prefix for any
absolute shared library paths; many runtime loaders store the absolute
paths to the shared library in the target program's memory. If you use
@samp{solib-absolute-prefix} to find shared libraries, they need to be laid
out in the same way that they are on the target, with e.g.@: a
@file{/usr/lib} hierarchy under @var{path}.
You can set the default value of @samp{solib-absolute-prefix} by using the
configure-time @samp{--with-sysroot} option.
@kindex show solib-absolute-prefix
@item show solib-absolute-prefix
Display the current shared library prefix.
@kindex set solib-search-path
@item set solib-search-path @var{path}
If this variable is set, @var{path} is a colon-separated list of directories
to search for shared libraries. @samp{solib-search-path} is used after
@samp{solib-absolute-prefix} fails to locate the library, or if the path to
the library is relative instead of absolute. If you want to use
@samp{solib-search-path} instead of @samp{solib-absolute-prefix}, be sure to
set @samp{solib-absolute-prefix} to a nonexistant directory to prevent
@value{GDBN} from finding your host's libraries.
@kindex show solib-search-path
@item show solib-search-path
Display the current shared library search path.
