not really. it says ... The /etc/make.conf file is included from the appropriate Makefile which specifies the default settings for all the available options. Options need only be specified in /etc/make.conf when the system administrator wishes to override these defaults. ... and in (/usr/share/examples)/etc/make.conf you can find .. # CFLAGS controls the compiler settings used when compiling C code ... #CFLAGS= -O -pipe ... # To compile just the kernel with special optimizations, you should use # this instead of CFLAGS (which is not applicable to kernel builds anyway). ... #COPTFLAGS= -O -pipe ... to my understanding this explains what CFLAGS/COPTFLAGS are intended for and _implies_ you'd have to uncomment the flag definitions in /etc/make.conf to set them active, otherwise the settings specified in the respective Makefile would be used. I had explicitly specified COPTFLAGS (-O -pipe) but not CFLAGS and saw -O overriding -O2 when compiling a port... quite confusing that uncommenting the example settings in make.conf changes exactly nothing, since these are the (undocumented?) system defaults anyway. probably a doc issue? - or just my stupidity .-) _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
