linker-errors - D-Bus 链接问题

Question

我一直在尝试为 dbus 编译一个程序正如我在代码中提到的类似问题所建议的那样。我确实执行了它，如图所示:

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软件包，但错误仍然存​​在。

您是否为这些库安装了开发包，或者只是库本身？在 Debian/Ubuntu 上，您需要 libdbus-glib-1-dev和类似 -dev其他人的包裹；在 Fedora 上，你想要 dbus-glib-devel和类似的。
