If You Change Your m4 Build File
After you run Build, you will
likely find that you need to change one or more
items in your m4 build file.
Whenever you change that file, you will need to use
the -c switch
with Build to force it to
create a new Makefile with your
new information in it. You do this by adding the
-c switch to
Build’s command
line:
%./Build -c -f ../../builds/oursite.m4%./Build -c← if using devtools/Site
For large compiles, such as sendmail, this process can be lengthy, but it is necessary, for without it your m4 build file changes will mysteriously appear to have no effect.
