我在Windows 7（基本版）64位上安装了以下两个msi - 我从here下载了msi。
gstreamer-sdk-devel-x86_64-2013.6.msi gstreamer-sdk-x86_64-2013.6.msi 现在我正在尝试使用MinGW（GCC 4.8.1）构建this hello world程序，链接器给我带来麻烦，说：
C:\Users\Apelles\AppData\Local\Temp\ccwLMXuu.o: In function `gst_message_unref':
C:/gstreamer-sdk/0.10/x86_64/include/gstreamer-0.10/gst/gstmessage.h:347: undefined reference to `gst_mini_object_unref'

我遗失了哪些lib？
以下是我用于构建项目的选项（取自我的make输出）：

这有什么缺点？
我该怎么做才能解决这个问题？
答案 0 :(得分：3)
我怀疑你正在使用MinGW的默认GCC编译器，它针对的是x86架构，但你已经下载了x86_64版本的SDK。链接器可以找到库但我将无法使用它们。
我们强烈建议使用cerbero的构建系统来设置开发环境。它将负责下载一个工作工具链并编译所有构建依赖项（autotools，gettext，libtoo，pkg-config等...）
您可以在使用SDK构建单个项目
