无法编译 dbus-ping-pong

我已经从以下网站下载了文件 http://cgit.collabora.com/git/user/alban/dbus-ping-pong.git/tree/

我正在尝试使用命令来编译它

gcc pkg-config --libs --cflags dbus-1 dbus-glib-1-2 glib-2.0 -o dbus-ping-pong dbus-ping-pong.c

但是，我收到了错误：

我该如何解决这个问题？

答案1

链接内容放在最后，尝试一下：

gcc $(pkg-config --cflags dbus-1 dbus-glib-1) -o dbus-ping-pong dbus-ping-pong.c $(pkg-config --libs dbus-1 dbus-glib-1)

顺便说一句，使用该命令成功编译后，我启动了该程序并得到了：

错误：任何 .service 文件均未提供名称 com.example.DBus.Echo

您知道我们可以如何使用该程序吗？

附言：我使用了$( ... )而不是反引号，因为它没有正确传递表格。

PS2：我在自己的问题中找到了解决方案：

创建文件“/usr/share/dbus-1/services/com.example.DBus.Echo.service”，内容如下：

[D-BUS Service]
Name=com.example.DBus.Echo
Exec=/home/telecom/bachelordbus/dbus-ping-pong/dbus-ping-pong server
User=root

谢谢 Eliah 的解释。
