在 OS X 下编译 libmms

Question

我在 C 语言中的一些非常基本的静态库链接方面遇到了麻烦。该库是 libMMS 0.6.2，并且该程序非常简单。 libmms.a 和 test.c 位于同一文件夹中，头文件位于 ./libmms 下。 OS X Lion下编译器为llvm-gcc-4.2。

编译libmms:

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

测试.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 undefined symbol

我在这里错过了一些简单的东西吗？

似乎 libmms 依赖于 libiconv 和 glib，因此您还需要链接它们。
