编译 gst-rtsp-server 示例时出错

我目前正在尝试设置一个 Ubuntu 服务器来重新分配来自 IP 摄像机的 rtsp 馈送。

我看到gst-rtsp-server 库gstreamer 可以帮助我解决这个问题。

我安装了以下包：

sudo apt-get install libgstrtspserver-1.0-dev
sudo apt-get install gstreamer1.0-rtsp
sudo apt-get install libglib2.0-dev

然后我在我的桌面上克隆了 gst-rtsp-server 库 repo：

git clone https://github.com/GStreamer/gst-rtsp-server.git

但是，当我尝试编译一个 C 文件（gst-rtsp-server/examples/test-launch.c）时，该示例说明了如何使用 gcc 的库：

gcc test-launch.c -I/usr/include/gstreamer-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include

我收到以下错误：

/tmp/ccM7e45N.o: In function `main':
test-launch.c:(.text+0x2e): undefined reference to `g_option_context_new'

test-launch.c:(.text+0x1a6): undefined reference to `g_main_loop_run'

我错过了一些东西，但我不知道是什么……><'

该错误显然是由于缺少标题而引起的，但是哪一个以及在哪里可以找到它？

一如往常，感谢您的帮助/提示！

如果这返回了一些内容：

pkg-config --modversion gstreamer-rtsp-server-1.0

（对我来说，它返回1.14.1）

您可以使用以下 gcc 命令来编译所需的示例：

gcc -o test-launch  test-launch.c  `pkg-config --cflags --libs gstreamer-rtsp-server-1.0`

PS 在命令中，请确保使用反引号 ` 而不是撇号 '
