麒麟系统开发笔记（二）：国产麒麟系统搭建Qt开发环境安装Qt5.12

<div class="cl-preview-section">
<h1>前言</h1>
</div>
<div class="cl-preview-section">
<p>  开发国产应用，使用到银河麒麟V4，V10，本篇以V10记录，参照上一篇可安装V4、V7、V10三个版本，麒麟V4系自带了Qt，麒麟V10没有自带Qt，需要自己编译搭建环境。</p>

</div>
<div class="cl-preview-section">
<p>  参考博文《获取下载Qt安装包，Qt源码全国网址备忘录（不用注册Qt账户，即可下载各版本Qt安装包和Qt源码包）》<br>  需要哪个版本下哪个版本，笔者经常使用得是Qt5.9和Qt5.12两个大版本，本次下载Qt5.12.0。</p>

<h1>Qt安装</h1>

</div>
<div class="cl-preview-section">
<p>  （经过测试可下载linux版本的Qt安装）</p>

<div class="cl-preview-section">
<h2>步骤一：下载解压</h2>

</div>
<div class="cl-preview-section">
<p>  开始先准备编译源码，在编译源码的时候顺便测试了下linux安装包，发现可以安装，那么先使用安装包，因为编译比较耗费时间。<br>  &nbsp;<img src="https://img-blog.csdnimg.cn/dd8e576ba4b44ac2a1846273905d90e8.png"></p>
