【问题描述】：
我在我的 Windows 7（基本）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.msigstreamer-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，链接器给我带来了麻烦，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'
C:\Users\Apelles\AppData\Local\Temp\ccwLMXuu.o: In function `main':

F:\projects\gstreamer/helloworld.c:26: undefined reference to `gst_object_unref'
collect2.exe: error: ld returned 1 exit status
我缺少哪些库？
以下是我用来构建项目的选项（取自我的make 输出）：
gcc helloworld.c -ggdb -Wall -Wextra -ansi -std=c99 -Wno-unused-parameter -mms-bitfields -IC:/gstreamer-sdk/0.10/x86_64/include/gtk-2.0 -IC:/ gstreamer-sdk/0.10/x86_64/lib/gtk-2.0/include -IC:/gstreamer-sdk/0.10/x86_64/include/atk-1.0 -IC:/gstreamer-sdk/0.10/x86_64/include/cairo -IC: /gstreamer-sdk/0.10/x86_64/include/gdk-pixbuf-2.0 -IC:/gstreamer-sdk/0.10/x86_64/include/pango-1.0 -IC:/gstreamer-sdk/0.10/x86_64/include/glib-2.0 -IC:/gstreamer-sdk/0.10/x86_64/lib/glib-2.0/include -IC:/gstreamer-sdk/0.10/x86_64/include/pixman-1 -IC:/gstreamer-sdk/0.10/x86_64/include/ fontconfig -IC:/gstreamer-sdk/0.10/x86_64/include/freetype2 -IC:/gstreamer-sdk/0.10/x86_64/include -IC:/gstreamer-sdk/0.10/x86_64/include/libpng15 -mms-bitfields -IC :/gstreamer-sdk/0.10/x86_64/include/gstreamer-0.10 -IC:/gstreamer-sdk/0.10/x86_64/include/glib-2.0 -IC:/gstreamer-sdk/0.10/x86_64/lib/glib-2.0/包括 -IC:/gstreamer-sdk/0.10/x86_64/include/libxml2 -LC:/gstreamer-sdk/0.10/x86_64/lib -lgtk-win32-2.0 -lgdk-win 32-2.0 -latk-1.0 -lgio-2.0 -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0 -lintl -LC:/gstreamer-sdk/0.10 /x86_64/lib -lgstinterfaces-0.10 -lgstreamer-0.10 -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lxml2 -lglib-2.0 -lintl
这其中缺少什么？
我应该怎么做才能解决这个问题？
【问题讨论】：
-
可能是 gstreamer 本身，因为
gst_init不可用。 -
@MarcB：安装的msi不包含它吗？我没有安装什么（或在配置时错过了）？
-
你有
-lgstreamer-0.10在那里，但只有当 gstreamer 的东西在包含/链接器路径中时才有用。 -
@MarcB：我可以猜测路径中缺少一些 特定的 gstreamer 内容，但我需要知道 什么 那具体的东西是什么？
