The -L switch is used
to list library directories on the command line. (See
-I in -I for one
example.) The value listed with this -L switch is
appended to the values specified in your site-file with
confLIBDIRS (confLIBDIRS), and to
whatever values might be preset as defaults in your
devtools/OS file. The final assembled value is
made a part of your configuration file, and is also made the value of
the LIBDIRS directive in your Makefile.
Multiple -L switches can be used to specify a
series of library directories to search. For example:
% ./Build -L/usr/local/lib -L/usr/tools/lib
In general, library directories should be listed with the
confLIBDIRS build macro (confLIBDIRS) in your m4 build file,
instead of on the command line.
