Thanks kernel_panic,
probably I have not explained well the problem. What I need is create the source tarball to install with configure/make/make install on a linux system. Searching over the net I read that are necessary 2 starting files: configure.in and Makefile.am; I have trouble creating this two files.

After further searching I found cmake and with little editing I have created my first source tarball of a very simple qt4 application (not that of the discussion).

Now I am trying to manage new stuffs, like images not compiled in the executable (used on runtime): in which folder of the filesystem I have to put them? in /usr/share/myapplication? Which changes I have to make to my code so that the executable (in /usr/bin, for example) finds the images (in /usr/share/myapplication, for example)?

If needed I'll post new questions.

Bye
