26.4 Building with a Cross Compiler

It is possible to build a program which uses GNU Autotools on one system and to run it on a different type of system. In other words, it is possible to build programs using a cross compiler. In this section, we explain what this means, how to build programs this way, and how to write your `configure' scripts to support it. Building a program on one system and running it on another is sometimes referred to as a Canadian Cross(69).
