Question

我在使用C语言中的一些非常基本的静态库链接时遇到了问题。该库是libMMS 0.6.2，程序就像我能做到的那样简单。 libmms.a和test.c位于同一文件夹中，头文件位于./libmms下。编译器是OS X Lion下的llvm-gcc-4.2。

编译libmms：

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

test.c的：

#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

给了我一长串未定义的符号

我在这里错过了一些简单的东西吗？

似乎libmms取决于libiconv和glib，因此您也需要将这些链接起来。

在OS X下编译libmms
