I did a CVSUP at ~7:00 PM EST (UTC-5:00) last night (09/01/2002), and then did buildworld/buildkernel. When I used this to update a machine this morning, I find that vmstat has quit working: % vmstat 5 vmstat: undefined symbols: _kmemstatistics _bucket _zlist % uname -a FreeBSD news.ums.edu 4.5-PRERELEASE FreeBSD 4.5-PRERELEASE #0: Wed Jan 9 18:04:43 EST 2002 malmberg@cvsup.usmh.usmd.edu:/usr/src/sys/compile/NEWS i386 I spent a while trying to figure out what library was missing, until I looked the source for vmstat -- the symbols are missing from the kernel symbol table. I believe the problem relates to making kernel global variables static where possible -- these three need to be available outside the kernel. I'm doing a new build with the changes below to see if they fix the problem.
