Installing i4uc in Linux is a more complex task as it needs to be compiled.
Besides having the basic toolchain (gcc, make, binutils, etc.), your system should have the following libraries:
Note that some distributions needs the development version of the library. For example: libglib-dev (debian based), glib-devel (fedora based), etc.
The latest version of the source code can be downloaded from here. Then run the following commands in console:
$ tar -jxvf i4uc-[version].tar.bz2
$ cd i4uc-[version]
$ ./configure
$ make
$ sudo make install
