Configuring the Default Search Paths
The default search paths used by the runtime linker are
/lib
and /usr/lib
for 32-bit application. For 64-bit applications, the
default search paths are /lib/64
and
/usr/lib/64
. These search paths can be
administered using a runtime configuration file created by the
crle
(1) utility. This file is often a useful
aid for establishing search paths for applications that have not
been built with the correct runpaths.
A configuration file can be constructed in the default location
/var/ld/ld.config
, for 32-bit
applications, or /var/ld/64/ld.config
, for
64-bit applications. This file affects all applications of the
respective type on a system. Configuration files can also be created
in other locations, and the runtime linker's
LD_CONFIG
environment variable used to select
these files. This latter method is useful for testing a
configuration file before installing the file in the default
location.
