/usr/ucb/ld is the link editor for the BSD Compatibility Package. /usr/ucb/ld is identical to /usr/ccs/bin/ld (see ld(1)) except that BSD libraries and routines are included before the base libraries and routines.

/usr/ucb/ld accepts the same options as /usr/ccs/bin/ld, with the following exceptions:

-Ldir

Add dir to the list of directories searched for libraries by /usr/ccs/bin/ld. Directories specified with this option are searched before /usr/ucblib and /usr/lib.

-Y LU,dir

Change the default directory used for finding libraries. Warning: This option may have unexpected results, and should not be used.

/usr/lib

/usr/lib/libx.a

/usr/ucblib

/usr/ucblib/libx.a
