Hello everyone!
I tray to compile one program,now in 11.2 but i can't find this "GTK+-2.0" maybе lib or dev is need.Here is a log-
checking for gtk... configure: error: Package requirements (gtk+-2.0) were not met:

No package 'gtk+-2.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables gtk_CFLAGS
and gtk_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
