Every time it's been discussed, the conclusion reached has been "stop setting CFLAGS, you're overwriting any previous definition used, which may be causing problems for you. Use += or COPTFLAGS." Even the Handbook explains the dangers of using CFLAGS= when one should be CFLAGS+=. http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/dads-cflags.html http://lists.freebsd.org/pipermail/freebsd-current/2004-August/034763.html http://lists.freebsd.org/pipermail/freebsd-questions/2004-February/036214.html http://www.nabble.com/buildworld-failure-(boot2.ld-too-big-when-CFLAGS-set-in-make.conf)-t4674137.html -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
