1. Shared library search paths

   Peter Eisentraut <peter_e@gmx.net> — 2000-07-18T18:18:14Z

   Some platforms (OSF/cc, HPUX) are already using -rpath or equivalent, so
   you don't have to specify a shared library search path at runtime. I think
   that a lot more platforms could use this. Can people comment on whether
   and how it works on their platform? Essentially,
   
   LDFLAGS+=-rpath '$(libdir)'
   
   might do the trick for most.

   For the SGI Irix 6.5, "man ld" gives:
   
        ....
   
        -rpath library_path
                  Adds the library_path to the search path for DSOs.  Each
                  library path is appended to the list of directories at the
                  time the executable or DSO is loaded.  This option directs
                  rld(5) to look in the named directories, but to look only
                  for DSOs, and to stop looking when the correct one is found.
   
                  This option can be specified only when the -shared or
                  -call_shared options are also in effect.  For more
                  information, see the rld(5) man page.  (C, C++, F77, F90)
   
       ....
   
        -shared   Produces a DSO, creates all of the tables for run-time
                  linking, and resolves references to other specified shared
                  objects.  The object created can be used by the linker to
                  make dynamic executables.  (C, C++, F77, F90)
   
       ....
   
   Hope this helps.

   for all the stuff I'm doign lately, I just do:
   
   setenv LDFLAGS "-R/usr/local/pgsql/lib -R/usr/local/lib"
   
   and let configure handle the rest ...

   For linux (at least gcc 2.7.x and 2.95.2 systems):
   
   if specified in the compilation step,
   
     -Wl,-rpath $(libdir)
   
   or if specified directly to the linker
   
     -rpath $(libdir)
