Hi all,

I try to figure out the link options for specifying RPATH/RUNPATH
under Darwin. I need this to overcome the need of setting
LD_LIBRARY_PATH with Grid Engine as described in

  http://gridengine.sunsource.net/issues/show_bug.cgi?id=2090

with other OSes there are link options that allow library pathes
be set *relative* to the executable path at the time when the executable is linked through

  Solaris: -R $ORIGIN/../lib
  Linux:   -rpath $ORIGIN/../lib

I believe there must be something related for Darwin, but I
found no such in ld(1) man page.

Anyone knowing this?

$ORIGIN on solaris and linux allow you to specify the library location relative to the application or library that needs it. For similar options on darwin see the man page for install_name_tool(1) and the dyld release note for information about @executable_path and @loader_path. 

Ok. Then it seems to be necessary to run

   install_name_tool -change <libname> @executable_path/<relative_path>/<libname> <executable>

for each library dependency of an executable where a relative path shall be in effect.

Thanks, Peter!

Cheers,
Andreas
