Like much open source Linux software, irmix must be built from source.
This entails the following steps from a console:

  ./configure
  make
  make install

The following options exist for customising irmix at the configure stage:

  --disable-xft
Turns off the transparency effect, and allows linking without Xft.

  --disable-icons
Turns off the icons, and allows linking without the Xpm library.

These two features will be automatically disabled if the appropriate
libraries are not available.

Once you've compiled and installed irmix, you will also have to adjust
your .lircrc file - the commands supported by irmix are detailed in the
README file.
