在OS X下编译libmms

Question

我在C中连接一些非常基本的静态库时遇到了问题。这个库是libMMS 0.6.2，而且这个程序也是我所能做的最简单的。libmms.a和test.c在同一个文件夹中，头文件在./libmms下。编译工具为OS X Lion下的llvm-gcc-4.2。

编译libmms：

CFLAGS="-march=x86_64" ./configure
make

test.c：

#include <stdio.h>
#include "libmms/mms.h"

int main(void)
{
    mms_t *mms = mms_connect(NULL, NULL, "mms://some.url.com", 128*1024);
    return 0;
}

编译程序：

gcc -o test test.c libmms.a

这给了我一长串未定义的符号

我是不是漏掉了什么简单的东西？

看起来libmms依赖于libiconv和glib，所以你也需要把它们联系起来。
