make.conf

Is there a way to tell make to always accept the default flags?

The default behaviour after issuing "make install clean" is a "sysinstall" style blue window where the user can check and uncheck flags.

One way is to write all the flag options and values in make.conf prior to installation. I guess I could write a script that extracts the default flags from each Makefile and adds them to make.conf. But is there another, simpler way?

set the env. variable BATCH to "yes". In bash, you can do:

BATCH="yes" make install distclean
