can't compile objective-c

Any time I try to compile the following:

@interface hello
    - (void) say_hello: (char*) s;

@implementation hello
    - (void) say_hello: (char*) s {
        printf( "%s\n", s );

I get the following error message:

 /tmp/cceeQbNJ.o: In function `__objc_gnu_init':
hello.m:(.text+0x58): undefined reference to `__objc_exec_class'

How can I fix this?
