What architecture have you set in the build settings? - Davyd Geyl

It looks like the linker is failing to link to libmms because it is of the wrong architecture. The project you are building appears to be for the iPhone simulator. Since the simulator runs on your computer it's architecture is i386 (or perhaps x86_64 depending upon the machine you are using). So basically you are compiling using i386 but when the linker tried to link to libmms it did not find that libmms had been compiled using the same architecture.

Since iOS devices use armv6 or armv7 architectures and the simulator uses i386, it can be quite difficult to switch back and forth between building for the actual device or building for the simulator since any external static libraries need to be built for all 3 architectures.

You'll likely need to rebuild libmms using the i386 architecture.
