This isn't a fix, unfortunately. It means that there are two instances of 'msgvec' with global scope, and the other one needs to be found too. You could probably just change the 'msgvec' in lex.c to be static in order to achieve that goal; then you need to work out which object(s) are exporting 'msgvec' as globals. Any chance of you doing that? Have a look at the output of 'nm' on each of the .o files, and see which (if any) export or reference _msgvec. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
