The current 21.5 from CVS fails to build for me with undefined references for some extent related inline functions. The last time this kind of failure happened to me it was because cvs wouldn't pull down some change for reasons unknown to me. I suspect that it's happening again. These are the commands I've tried. cvs -z9 -d :pserver:cvs＠cvs.xemacs.org:/pack/xemacscvs checkout -d xemacs-latest xemacs cvs -z9 -d :pserver:cvs＠cvs.xemacs.org:/pack/xemacscvs update -d xemacs-latest xemacs On the off chance that it's not the fault of CVS, here are the errors that happen at link time. There are several screens of output. alloc.o: In function `allocate_extent': /usr/local/src/xemacs-latest/src/alloc.c(.text+0x1ef2): undefined reference to `extent_ancestor' extents.o: In function `signal_single_extent_changed': /usr/local/src/xemacs-latest/src/extents.c(.text+0x185e): undefined reference to `extent_ancestor' /usr/local/src/xemacs-latest/src/extents.c(.text+0x1881): undefined reference to `extent_ancestor' /usr/local/src/xemacs-latest/src/extents.c(.text+0x18a4): undefined reference to `extent_ancestor' /usr/local/src/xemacs-latest/src/extents.c(.text+0x18af): undefined reference to `extent_aux_or_default' /usr/local/src/xemacs-latest/src/extents.c(.text+0x18d2): undefined reference to `extent_ancestor' /usr/local/src/xemacs-latest/src/extents.c(.text+0x18dd): undefined reference to `extent_aux_or_default' /usr/local/src/xemacs-latest/src/extents.c(.text+0x1900): undefined reference to `extent_ancestor' [...rest omitted...] (ice) gcc -v Using builtin specs. gcc version 2.95.3 20010315 (release) [FreeBSD] (ice) cat /usr/local/src/xemacs-latest/Installation uname -a: FreeBSD ice.wonderworks.com 4.5-RELEASE FreeBSD 4.5-RELEASE #0: Mon Jan 28 14:31:56 GMT 2002 murray＠builder.freebsdmall.com:/usr/src/sys/compile/GENERIC i386 ./configure 'i386-unknown-freebsd4.5' '--prefix=/local/tmp' '--bindir=/local/tmp/bin/i386-unknown-freebsd4.5' '--use-union-type=yes' '--rel-alloc=no' '--site-libraries=/usr/local/lib' '--site-includes=/usr/local/include' '--cflags=-g' '--with-sound=native,noesd' '--package-path=~/.xemacs::/usr/local/src/xemacs-packages' '--debug=no' '--error-checking=none' '--verbose' XEmacs 21.5-b6 "bok choi" configured for `i386-unknown-freebsd4.5'.
