Building a C library Objective-C wrapper framework

Hi,
I'm writing a framework that basically provides an OOP wrapper around a C library (used mainly on linux). I need to build this framework with the C library properly linked. I'm not exactly sure how to do it. Currently I have it as an SDK, and just included the compiled .dylib, and header files in it. It builds fine, but I'm not able to use the framework in an application. What happens is that I try to #import <MyFramework/MyFramework.h>, and gcc complains that it can't find theclib.h. "theclib.h" is found in MyFramework/Headers/theclib.h, but it's of course only looking in the default header search paths. I expect that even if I get this header problem solved, it won't be able to actually link against the framework.


I'd like some guidance on how to go about doing this properly. I'm obviously not setting the install_path right - I'm completely confused about that. Basically I want to create a framework that completely encapsulates (so that it's transparent to the user) the C library, and its depending libraries. All the developer using the framework should have to do is "#import <MyFramework/MyFramework.h>" and link against the framework - just like other Apple frameworks. I looked into Adium code, since that's the first open source application that comes to mind which does a similar thing (with libpurple). It appears they made a libpurple.framework. Would it be a good idea for me to create a theclib.framework and then link MyFramework.framework against theclib.framework? How are the install_paths supposed to be setup?

Here's a bit of a "dependency" graph:
MyFramework -> theclib
theclib -> dependantlibA
theclib -> dependantlibB

theclib.framework would therefore have to encapsulate dependantlibA and dependantlibB. MyFramework.framework would have to encapsulate theclib.framework.

I come from a linux background so this is really confusing for me. On linux I just compile against the lib with the assumption that the lib will constantly stay in that place - plain and simple.

I wasn't sure if I was to post this here or some other mailing list, so sorry if it's the wrong one.
