This talk is not for people with heart conditions.
As users of FLOSS software we have, on occasion, the need to understand the configuration systems of the software we use. More often than not, when we’re compiling software, the first command we run is “./configure” and, more often than not, that program is generated by autoconf. This presentation will arm you with just enough knowledge to be dangerous. You will learn how to write configure template files and, yes, you will learn about m4. m4 is the macro processor language used by autoconf.
At the end of this talk you will have a basic understanding of the structure and syntax of configure template files. You will be able to define and use configure switches such as `—enable-foo’ and `—with-foo’. Finally, you will be able to generate Makefiles which have information about how the configure process was run. Knowing this you will have enough foundation that, with a little effort, you can dig into the configuration processes of open source projects which use autoconf.
