I'm confused why hard link cannot point to directory. It can just point to the inode of the directory file, i suppose. thanks for any hints in advance, lin ----- Original Message ----- From: "John Birrell" <jb@cimlogic.com.au> To: "David O'Brien" <obrien@FreeBSD.ORG> Cc: "John Birrell" <jb@cimlogic.com.au>; <current@FreeBSD.ORG> Sent: Monday, March 13, 2000 3:12 PM Subject: Re: Weak symbols in libc_r broken?

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.
