26.4.5 Canadian Cross Tools

You must explicitly specify the cross tools which you want to use to build the program. This is done by setting environment variables before running the `configure' script. You must normally set at least the environment variables `CC', `AR', and `RANLIB' to the cross tools which you want to use to build. For some programs, you must set additional cross tools as well, such as `AS', `LD', or `NM'. You would set these environment variables to the build cross host tools which you are going to use.

For example, if you are building a Solaris program on a GNU/Linux system, and your GNU/Linux cross Solaris compiler were named `solaris-gcc', then you would set the environment variable `CC' to `solaris-gcc'.
