I'm sorry to have to ask. What's a profiled library anyway?
Thanks

I use:
CFLAGS= -02 -pipe -m486
COPTFLAGS= -O -pipe
Ths first adds a little more optimization for ordinary builds, such as the
ports collection. The second is the recommended setting for the kernel.
There are a few other useful settings besides:
# Avoid compiling profiled libraries
NOPROFILE= true
The average user has no use for these anyway, and you can save a little
time and disk space by not compiling them when doing a "make world".
If you've installed the Lesstif port:
HAVE_MOTIF= yes
If you're a USA resident (certain ports check the setting of this
variable):
USA_RESIDENT=YES
Another setting I find very useful is:
FORCE_PKG_REGISTER= YES
This will force a port to install and register itself when you do a "make
install", even if it's already installed.
Last but not least, if you use cvsup to update your sources and/or ports
collection:
SUP_UPDATE= yes
#
SUP= /usr/local/bin/cvsup
SUPFLAGS= -g -L 2
SUPFILE= ${STABLESUPFILE}
CURRENTSUPFILE= /root/current-supfile
STABLESUPFILE= /root/stable-supfile
DOCSUPFILE= /root/doc-supfile
PORTSSUPFILE= /root/ports-supfile
I've defined a few extra variables here (CURRENT..., STABLE..., DOC...,
PORTS...). THE DOC and PORTS supfiles enable you to go to either
/usr/doc or /usr/ports and do a "make update" to cvsup the latest changes.
CURRENT and STABLE are just some aliases I created; the name that's
actually used is, of course, just plain old SUPFILE. This, like DOC and
PORTS, enables you to go to /usr/src and do "make update".
Hope this helps.
