Postfix – compilation

Postfix does not have a configure script, so you need to add proper paths and libraries when you creating Makefiles (make makefiles). I must admit, that Postfix code is one of the least problematic code to compile on differents systems. To make my compilations reproducible, I wrote a script and set proper options for compilation.

#!/bin/sh

# for GCC:
#CC=gcc
#CFLAGS="-O2 -mcpu=v9"
#MAKE=gmake

# for Sun Studio
CC=cc

CXXFLAGS=$CFLAGS

After unpacking sources downloaded from Postfix site, I run a script:

./drf_postfix-2.9.3_conf

Installation after su root or sudo, but when you already have Postfix installed, you can do make upgrade to the same directory. You can upgrade Postfix without shutting down, but I always do a restart Postfix after upgrade.
