checking for GTKSHARP... yes checking for GLADESHARP... Requested 'glade-sharp-2.0 >= 2.10.0' but version of Glade is 2.4.3 configure: error: Package requirements (glade-sharp-2.0 >= 2.10.0) were not met: Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GLADESHARP_CFLAGS and GLADESHARP_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. ankur@ubuntu:~/gnome-sharp$ sudo apt-get install gladesharp Reading package lists... Done
