D-Bus链接问题

Question

我一直在尝试为dbus编写一个程序，正如我在代码中提到的类似问题所建议的那样。我执行了它，如下所示：

gcc `pkg-config --cflags dbus-glib-1` \
  `pkg-config --cflags dbus-1` \
  `pkg-config --cflags glib-2.0` \
   dbus-example.c \
  `pkg-config --libs dbus-glib-1` \
  `pkg-config --libs dbus-1` \
  `pkg-config --libs glib-2.0`

我仍然收到以下错误：

Package dbus-glib-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `dbus-glib-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'dbus-glib-1' found
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found
Package dbus-glib-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `dbus-glib-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'dbus-glib-1' found
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found 

我安装了上面提到的包，但错误仍然存在。

您是否安装了这些库的开发包，或者只是安装了库本身？在Debian/Ubuntu上，你需要为其他人提供libdbus-glib-1-dev和类似的-dev包；在Fedora上，你需要dbus-glib-devel和类似的包。
