I have a problem (not even sure that it is a bug for now) with linking native library to xamarin IOS project.
At the start i was getting error, described @ http://forums.xamarin.com/discussion/3381/native-binding-errorundefined-symbols-for-architecture-i386-for-mono-libs/p1.
But by somehow error has gone (some kind of a magic actually...), but another one has been occurred - 50 symbols duplicated for architecture i386. All errors relate to native library pjsip.
Same library links and runs absolutely normally with IPhone XCode application.
I have attached archive with example projects for Xamarin(monotouch folder) and Xcode(xcode folder). Both projects link to libpjsip.a located at the root folder.
Best Regards, Alex D

XCode and Xamarin projects example
This is a problem with the native library, it really has duplicate symbols.
You can reproduce it in the xcode project by going to the project's Build Settings and:
* Disable "Dead Code Stripping"
* Adding "-all_load" to "Other Linker Flags"
You should contact the provider of the libpjsip.a library and have them fix it.
