View Full Version : Beginning GTK - Undefined References

February 27th, 2011, 07:16 AM
I'm trying to learn how to use the C++ GTK library. I've tried with GTKMM, but it's not working. I've also used gtk.h. I'm developing in C++ eclipse. Now, with an EXTREMELY basic script (11 lines) it will include gtk.h, but it says undefined reference to gtk_init. Please. Help. HELP. HHHEEELLLPPP. :(

Make sure that you have the packages build-essential (http://packages.ubuntu.com/maverick/build-essential) and libgtk2.0-dev (http://packages.ubuntu.com/maverick/libgtk2.0-dev) installed.

You also need to link GTK+ and its companion libraries when compiling. In a terminal, you should be able to compile your program with the command

g++ -o yourprog yourprog.cpp `pkg-config gtk+-2.0 --cflags --libs`

There is probably an easy way to link the necessary libraries in Eclipse as well, but I have never used that application.

*Headdesk* How come none of the other g++ commands for compiling this didn't work? >_> Anyway, thank you. :)
