If you are trying to compile a gtk-3 application and if you don’t have development package installed here is the error you can get:
configure: error: Package requirements (gtk+-3.0 >= 3.0.0) were not met:
No package ‘gtk+-3.0’ 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.
If you encounter this error in Fedora, you should install gtk3-devel. In terminal, type in the following:
su -c 'yum install gtk3-devel'
If you encounter this in Ubuntu, you should install libgtk-3-dev. To do so, type in the following in terminal:
sudo apt-get install libgtk-3-dev
Hope this helps.
