XCode 4.3: Static Library Generation
===

I've done a some looking around but most of the answers I've found have been or felt incomplete and have left me a little confused. I have been given a C Library that I need to compile into a static library using XCode 4.3 and then use in a separate iOS app project, but I'm unsure about how to proceed. I'm not sure if the directory structure matters or not, but here it is anyways:

    Library -> Section1 -> src -> .c files
                        -> sec1 -> .h files
                        -> sec1.h 
            -> Section2 -> src -> .c files
                        -> sec2 -> .h files
                        -> sec2.h

I've been trying to work from this: http://blog.stormyprods.com/2008/11/using-static-libraries-with-iphone-sdk.html which was linked in a question similar to this one though being from 2008 its fairly out of date, nor could I get it to work. There is also this question: http://stackoverflow.com/questions/7605805/including-external-c-library-with-xcode but it doesn't go into the details of actually generating the library, before then including in a separate project. 

If someone could provide a clear and up-to-date answer I, and many others, would very much appreciate it I'm sure. Let me know if any more information is needed!
