Wmii is licensed under the MIT/X Consortium License, which basically means it is free software, and you are free to download it from http://wmii.de free of charge 5.
First of all, have a look if there are binary packages of wmii in your distribution. Debian, Ubuntu and Gentoo should already have good packages. If you found a trustworthy package, you may now safely skip this section.
For all those who are still reading this, let me tell you that you are on the good side because if you grab the sources and compile them yourself you'll benefit from having everything in it's original place, which will ease your use of wmii.
cd /path/to/wmii-previous
make uninstall && make clean
In case you're installing a newer version of wmii, this is the first thing you should do otherwise you'll end up mixing binaries, configuration files and manual-pages of different and potentially incompatible versions.
tar xzf wmii-3.tar.gz
cd wmii-3
vim config.mk
The most important variable to set is the PREFIX, which
states, where you want wmii-3 to be installed to. If you are unsure, keep the
default, it won't break your system.
make && make install
#!/bin/sh
exec wmii
Now you are finished. Please note that autoconf tools are not used for various reasons 6. Please don't ask the wmii developers to use autoconf, they won't listen to you.
