You're confusing run-time link paths with compile-time link paths. ldconfig is only used at runtime, to resolve shared library dependencies. -L flags on the gcc line are only used at link time, to resolve both shared and static library dependencies. ldconfig paths can be specified in /etc/rc.conf. Unfortunately, there's no place to add compile-time library paths. Most software uses autoconf to scan common directories for the libraries it needs. -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
