How to check for linux prerequisites?

[ivan17]

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

or build a package (rpm or deb)

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

or build a package (rpm or deb)

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?
