From a390e490aa4d30655f42e2f311f093d74962ddc5 Mon Sep 17 00:00:00 2001 From: Rich Megginson Date: Fri, 19 Oct 2007 20:05:12 +0000 Subject: Resolves: bug 340361 Bug Description: build links wrong libdb on 64-bit systems Reviewed by: nhosoi (Thanks!) Fix Description: Once again, libtool attempts to be helpful but is instead harmful. If you have both db4-devel.i386 and db4-devel.x86_64 installed, this will install /usr/lib/libdb-4.N.la. If you use libtool to link with -ldb-4.N, and you do not specify a search path, libtool will attempt to find this library in it's default search path, which is something like /usr/lib/gcc/x86_64/blahblahblah/../../../lib. This will find /usr/lib/libdb-4.N.la and will use the information in that file and link the object with /usr/lib/libdb-4.N.so, instead of just passing -ldb-4.N through to the linker which is what it ought to do (darn libtool). In order to make libtool do the right thing, we must pass in -L$libdir -ldb-4.N to libtool so that it will use $libdir first in its search path.
