This is in contrast with manual page and with logic.

       -Lsearchdir
       --library-path=searchdir
           Add path searchdir to the list of paths that  ld  will
           search  for  archive libraries and ld control scripts.
           You may use this option  any  number  of  times.   The
           directories  are  searched  in the order in which they
           are specified on the command line.  Directories speci?
           fied  on  the  command  line  are  searched before the
                                              ^^^^^^^^^^^^^^^
           default directories.  All -L options apply to  all  -l
           options,  regardless of the order in which the options
           appear.

           The default set of paths searched (without being spec?
           ified  with  -L) depends on which emulation mode ld is
           using, and in some cases also on how  it  was  config?
           ured.

           The  paths can also be specified in a link script with
           the "SEARCH_DIR" command.  Directories specified  this
           way  are  searched  at  the  point in which the linker
           script appears in the command line.

The smsd is linked with command:
gcc -Wl,--rpath -Wl,/usr/local/lib smsd.o lowlevel.o  -lpthread `glib-config
--libs` -s -rdynamic -L../common -lgnokii -ldl -L/usr/X11R6/lib -lXpm -lX11
-o smsd


The only wrong thing here is -Wl,--rpath -Wl,/usr/local/lib. It is from
$(TOPDIR)/Makefile.global. Pawel said the he will look for
reason why it is there some time ago. If he will find that it is necessary
for gnokii, I will have to ignore $(TOPDIR)/Makefile.global because it is evil.

The idea of networking is probably as old as telecommunications itself.
Consider people living in the stone age, where drums may have been used to
transmit messages between individuals. Suppose caveman A wants to invite
caveman B for a game of hurling rocks at each other, but they live too far
apart for B to hear A banging his drums. So what are A's options? He could
1) walk over to B's place,
2) get bigger drum,
3) ask C, who lives halfway between them, to forward the message.
The last is called networking.
