[SDL] Installation of binary apps on linux

[Gabriele Greco]

I'd like to make a binary installer for a game I wrote on linux, this 
game obviously use sdl :)

I'm just wondering if there are some guides or tutorial about how to 
perform the following steps, obviously I've googled around a few hours 
before posting here, but with almost not useful results...:

- Obtain a compressed "clickable" installer that runs with almost any 
libc version.

(loki installer + makeself?)

- Be able to add KDE / Gnome menu entry in the correct way.

(no idea at all about this, I've seen that many distributions place the 
small xml file used to describe the menu entry in different places, also 
the format is slightly different in kde & gnome..., freedesktops may helps?)

- Be sure that the game uses my libraries and not the ones provided on 
the user machine (to avoid compatibility issues).

(export LD_LIBRARY_PATH=./mylibs:$LD_LIBRARY_PATH in the game startup 
script is enough?)
