如何安装Mx库？Debian下编译Vala代码时Mx命名空间缺失问题解决

尝试运行Mx toolkit示例代码时，执行编译命令出现如下错误：

$ valac --pkg mx-1.0 mxgui.vala

mxgui.vala:4.7-4.8: error: The namespace name `Mx' could not be found
using Mx;
      ^^
Compilation failed: 1 error(s), 0 warning(s)

Debian稳定版系统已安装的Clutter相关包如下：

$ apt search clutter | grep installed

gir1.2-clutter-1.0/stable,now 1.26.4+dfsg-2 amd64 [installed]
gir1.2-cogl-1.0/stable,now 1.22.8-2 amd64 [installed,automatic]
gir1.2-coglpango-1.0/stable,now 1.22.8-2 amd64 [installed,automatic]
gir1.2-gtkclutter-1.0/stable,now 1.8.4-4 amd64 [installed]
libclutter-1.0-0/stable,now 1.26.4+dfsg-2 amd64 [installed]
libclutter-1.0-common/stable,stable,now 1.26.4+dfsg-2 all [installed,automatic]
libclutter-1.0-dev/stable,now 1.26.4+dfsg-2 amd64 [installed]
libclutter-gtk-1.0-0/stable,now 1.8.4-4 amd64 [installed]
libclutter-gtk-1.0-dev/stable,now 1.8.4-4 amd64 [installed]
libxkbcommon-dev/stable,now 1.0.3-2 amd64 [installed,automatic]
libxkbcommon0/stable,now 1.0.3-2 amd64 [installed,automatic]

• 问题根源：仅安装了Clutter相关依赖，但Mx Toolkit是独立的UI组件库，对应的开发包未安装，导致Valac无法识别Mx命名空间。
• 解决步骤：
  1. 安装Mx Toolkit的开发包，Debian稳定版中该包名为libmx-1.0-dev，执行命令：

     sudo apt update && sudo apt install libmx-1.0-dev
     

  2. 安装完成后重新执行编译命令：

     valac --pkg mx-1.0 mxgui.vala
