GTK2 Compatibility Package Compatibility Wrapper for GTK+2 Wrapper for pkg-config file and M4 macros, which simulates presence of GTK+2, but tries to use GTK+3. Using it instead of GTK+2 development files allows to force linking of some applications with new libraries without any effort. Usage: Simply replace old devel packages by gtk2-compat in your system. Programs will be compiled with GTK+2, if possible. Don't expect that you will be able to compile all projects!
