How do I check if the user system has needed libraries installed (gtk2
and gdk-pixbuf; or qt)?

I really would like to output some meaningful message instead of
having...
Code: [Select]./xlstd: error while loading shared libraries: ./xlstd:
undefined symbol: gtk_tool_button_get_type... written on the stderr?

With ldd can you check the dependencies of your program

http://linux.die.net/man/1/ldd

or build a package (rpm or deb)

i'm talking about a target (end-user's) system.

well that is one way... but i'd like to check at runtime.

i was thinking something along the lines of trying to dynamically link
to one of the needed libraries and seeing whether it was successful...
that would probably be done from a separate (loader) program. anyone
had any experience with that?
