I wrote an application about proxy setting, it compiles success, but link error, error information shows above. What libs should I link with according to the information above ?

These symbols are all from SystemConfiguration.framework. This WebKit-dev list is specifically about development of and with WebKit. In the future, it would be better to ask development questions about different topics on a different mailing list, such as <http://www.omnigroup.com/mailman/listinfo/macosx-dev

for general Mac development questions, or one of the many lists hosted on <http://lists.apple.com/> (<http://lists.apple.com/mailman/listinfo/macnetworkprog appears relevant to your interests based on your recent emails).

Kind regards, - Mark
