The general steps to build Postfix from the source files are to obtain the software bundle, uncompress it, compile it, and install it. The tools you need are common on nearly all distributions of Unix: gzip, tar, make, and a C compiler. Postfix generally expects the GNU gcc compiler, but you can also build it with your platform's native compiler, as long as it supports ANSI C.
