I followed the guide at Build fat static library (device + simulator) using Xcode and SDK 4+ to build the libmms ( https://github.com/kosher-penguin/xcode-libmms ), and got a fat static library, but it seems not work. I got errors when add the library to my project(xCode4.2+iOS5.0):
Undefined symbols for architecture armv7:
"_iconv_close", referenced from:
_mms_connect in libMMS.a(mms.o)

clang: error: linker command failed with exit code 1 (use -v to see invocation)
Firstly,I clone the code from https://github.com/kosher-penguin/xcode-libmms.git Secondly, I open it with xCode4.2, and add the follow script to Run Script(Build Phases), and then run the project. Thirdly, I copy the file named libmms.a in the folder named Release-universal, and then add the library to a new project. Fourthly, in the new project,add the header file from xcode-libmms project, import mms.h and mms_config.h, and call the function mms_connect, and then build it, but get the errors.

Please give me some help, thank you.
update: After add libiconv library, the error as follow:
