Undefined symbols when linking PhoneGap static lib

2019-09-04 17:50发布

问题:

I am working on providing PhoneGap functionality in a UIWebView in MonoTouch. I have tested the functionality in Objective C and the static library works correctly there. However, when I try and link the PhoneGap static library into my MonoTouch application I get a long list of undefined symbols.

I have included all the header files for the PhoneGap library and I have also ensured that 'Compile for thumb' is unchecked when compiling the PhoneGap library. So I am not sure what I am missing and the error messages don't mean much to me. I will quote them here (it is a LONG list!), but hopefully someone here can enlighten me to what the linker is trying to tell me!

Here is the long list...

Hope this makes sense to someone here, because it is greek to me! ;)

Thanks

I found the problem; I was missing several framework entries that were required by the PhoneGap library. Specifically, these framework entries needed to be added to the gcc_flags:

-framework corelocation 
-framework mediaplayer
-framework messageui
-framework mobilecoreservices
-framework quartzcore
-framework systemconfiguration
-framework audiotoolbox
-framework avfoundation
-framework addressbook
-framework foundation
-framework coregraphics
-framework addressbookui
