You guys both managed to screw your build systems (I've got the
requested output from originator in a private email). We need
a working and consistent build system for a successful build,
and part of this requirement is that we trust the value of the
__FreeBSD_version definition from /usr/include/osreldate.h to
determine the version of the build system (headers, libraries,
etc.), OSRELDATE.
It is known that lex(1) prior to flex.skl,v 1.8 and gen.c,v 1.7
have backward compatibility issues and requires bootstrapping,
to not generate compiler warnings. The said revisions were made
on 2004/01/06, and at that time __FreeBSD_version was 502101, so
Makefile.inc1 bootstraps lex(1) ``.if ${BOOTSTRAPPING} < 502102'',
i.e., we stop bootstrapping on the next version bump that
happened on 2004/01/30.
You broke this because your installed /usr/include/osreldate.h
(the modification date is 2004/02/04) doesn't match the installed
world (/usr/bin/lex is as of 2004/01/03).
Now you tell me how you managed to screw it.
In return, I'll tell you how to proceed. Run buildworld like
this:
make buildworld OSRELDATE=3D502101
Sorry, but we can't protect you from shooting yourself in the
foot. ;)
If you're in a mood of often doing partial upgrades, including
headers, you might find it useful to set OSRELDATE=3D0, which
will do an aggressive bootstrapping -- assume that everything
bootstrappable needs to be bootstrapped.
