GCC complaining about undefined symbols when trying to compile .o for using as JNI.

I have some JNI code that I wrote using the some java code for android platform in 10.7 (Lion) and Xcode 4.3, but when I try to use the gcc, I get some strange errors.

Here is the output of mine, can anyone tell me whats going on?

Thanks.

Code:

MacBook-Pro:JNI $$ cc -dynamiclib -o hellojni.jnilib hellojni.o -framework JavaVM
Undefined symbols for architecture x86_64:
  "_print", referenced from:
      _Java_HelloJNI_printHello in hellojni.o
      _Java_HelloJNI_printString in hellojni.o
     (maybe you meant: _Java_HelloJNI_printHello, _Java_HelloJNI_printString )
ld: symbol(s) not found for architecture x86_64
