2.4 Automake Development

By 1994, Autoconf was a solid framework for handling the differences between Unix variants. However, program developers still had to write large `' files in order to use it. The `configure' script generated by autoconf would transform the `' file into a `Makefile' used by the make program.

A `' file has to describe how to build the program. In the Imake equivalent of a `', known as an `Imakefile', it is only necessary to describe which source files are used to build the program. When Imake generates a `Makefile', it adds the rules for how to build the program itself. Later versions of the BSD make program also include rules for building a program.

Since most programs are built in much the same way, there was a great deal of duplication in `' files. Also, the GNU project developed a reasonably complex set of standards for `Makefile's, and it was easy to get some of the details wrong.

These factors led to the development of Automake. automake, like autoconf, is a program run by a developer. The developer writes files named `'; these use a simpler syntax than ordinary `Makefile's. automake reads the `' files and produces `' files. The idea is that a script generated by autoconf converts these `' files into `Makefile's.

As with Imake and BSD make, the `' file need only describe the files used to build a program. automake automatically adds the necessary rules when it generates the `' file. automake also adds any rules required by the GNU `Makefile' standards.

The first version of Automake was written by David MacKenzie in 1994. It was completely rewritten in 1995 by Tom Tromey.
