I don't think it is the linker's fault. To me it makes no sense to have a weak symbol and a strong symbol of the same name in the same library. I deleted the weak definitions in the _THREAD_SAFE PRSYSCALL in lib/libc/i386/SYS.h and the problem goes away. I don't understand why Jason needed to add them in the first place. -- John Birrell - jb@cimlogic.com.au; jb@freebsd.org http://www.cimlogic.com.au/ john.birrell@ca.com john.birrell@opendirectory.com.au To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message ________________ Email Forwarding Service Brought To You By: http://www.bn3.com.
