...[snip lots of dependencies]...
Yes of course, but in the case of desktop applications, as you have
realized, there is a huge dependency list. This is the negative aspect
of using the larger libraries like Qt, GTK etc... At some point you
application will stop working because a standard install of whatever
Linux distro might not supply the correct dependencies out of the box.
Alternatively, make sure you use a toolkit that has *much less
dependencies*. This is exactly why I started the fpGUI Toolkit project.
Our applications are very "lite" when it comes to dependencies, so have
a greater chance of still running many years from now. Even the reverse
is possible, we can run todays application on a ten year old Linux
distro without problems too (we actually tested this, using Suse 8 &
Suse 9).
Compare a default fpGUI application dependencies against what you
posted. This dependency can be further reduced by switching to non
anti-aliased fonts - but that just makes applications look ugly. :)
