Subject: passing options through g++/gcc to linker
Date: Sat, 11 Dec 1999 17:28:00 -0000	[thread overview]
Message-ID: <3852F6E1.67C0A5E8@csuhayward.edu> (raw)
In-Reply-To: <82gfhm$5qu$1@gail.ripco.com>

I would like to compile/link a program on Unix (SunOS) using g++/gcc
that specifies where the runtime library resides on the host machine. I
read in these pages a suggestion to pass options to the linker in one of
these ways:

g++ -Wl,-rpath,<path>
or
g++ -Xlinker -rpath -Xlinker <path>

Yet, when I try that (although there are no messages from complier or
linker that I see)
and then do the "ldd" command to see what libs the runtime file (a.out)
will use,
it is the same as if I don't specify the path.

e.g.  <path> (in above commands) set to    /mydir/lib    (where my
libstdc++.so.2.8.1 resides)
I thought would change the output of:
ldd a.out
from
/opt/gnu/lib/libstdc++.so.2.8.1
 to
/mydir/lib/libstdc++.so.2.8.1

I still don't understand how this works yet. Can anyone enlighten me?
Thank you, Dave
