$ORIGIN? That's yet another way to locate shared libraries. At run-time,
$ORIGIN is replaced with the pathname of the executable, and libraries
are searched for in the new path that results. Let's say you link a
program like this:
cc -o foo foo.c -Wl,-rpath='$ORIGIN/../lib'
Then, if the executable is installed in /opt/X/bin, the search path
becomes `/opt/X/bin/../lib'. Typically used by large commercial programs
which the user could install into any location, and they don't want the
user to muck about adjusting paths in /etc/ld.so.conf or LD_LIBRARY_PATH.
Incidentally, NetBSD's ld.elf_so seems overly sensitive about this. I
always thought that $ORIGIN always expanded to an absolute path rather
than a relative one. At least, that's how it is on Linux and FreeBSD.
Have the linker experts look at this, then file a PR if warranted.
