Re: Question regarding the dependency of GDK on other libraries

["Ruchi Lohani" <ruchi lohani gmail com>]

Can anybody explain me the significance of Requires and Requires.private
field in the pkg-config .pc file ?
For the gdk-x11-2.0 package, one Ubuntu system has some of the X libs like
Xcomposite, Xdamage etc in Requires field whereas another one has all of
them in Requires.private field.

This affect the applications using gdk as the application fails to load
these X libraries during run time. I am not very clear about the pkg-config
fields. Should there be a unique .pc file for a package like gdk and if so
then what all should be its dependencies?

Thanks
Ruchi
