麒麟系统开发笔记（八）：在国产麒麟系统上使用linuxdeployqt发布qt程序
<div class="cl-preview-section"><h1>前言</h1>
</div>
<div class="cl-preview-section">
<p> 在ubuntu上发布qt程序相对还好，使用脚本，但是在麒麟上发布的时候，因为银河麒麟等不同版本，使用脚本就不太兼容，同时为了实现直接点击应用可以启动应用的效果，使用linuxdeployqt发布qt程序。</p>
</div>
<div class="cl-preview-section"> </div>
<div class="cl-preview-section">
<h1>补充</h1>
</div>
<div class="cl-preview-section">
<p> 在ubuntu上发布程序遇到xcb问题，当我们将其部署到另外同样环境但是未装qt的环境下，运行起来一部分是xcb文件，有一部分解决后可以正常运行启用，另一部分直接段错误，程序宕掉（提示，段核心错误，已转存什么的），使用linuxdeployqt能解决此问题，也就是使用脚本打包的升级版本。</p>

<div class="cl-preview-section">
<h1>linuxdeployqt</h1>
</div>
<div class="cl-preview-section">
<p> Linux部署工具linuxdeployqt将应用程序作为输入，并通过将应用程序使用的资源（如库、图形和插件）复制到一个包中使其自包含。结果包可以作为AppDir或AppImage分发给用户，也可以放入交叉分发包中。它可以作为构建过程的一部分，在CMake、qmake和make等系统中部署用C、C++和其他编译语言编写的应用程序。当用于基于Qt的应用程序时，它可以绑定运行应用程序所需的Qt的特定最小子集。</p>

<h2>步骤一：下载解压</h2>
</div>

</div>
<div class="cl-preview-section">
<h2>步骤二：修改源码，去掉版本检查</h2>
</div>
<div class="cl-preview-section">
<p> 找到main.cpp源码，将这一段（在192行左右）注释掉：</p>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell">gedit tools/linuxdeployqt/main.cpp
</code></pre>
</div>
<div class="cl-preview-section">
<p> <img src="https://img-blog.csdnimg.cn/f41f38d3658e4d8c9e277d6c2fb08c79.png"><br> （注意：这一步不做会导致打包输出错误信息，具体看“入坑一”）</p>
</div>
<div class="cl-preview-section">
<h2>步骤三：安装依赖第三方库</h2>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell"><span class="token function">sudo <span class="token function">apt-get <span class="token function">install cmake
<span class="token function">sudo <span class="token function">apt-get <span class="token function">install patchelf
</span></span></span></span></span></span></code></pre>
</div>
<div class="cl-preview-section">
<h2>步骤四：使用cmake配置</h2>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell">cmake CMakeList.txt
</code></pre>
</div>
<div class="cl-preview-section">
<p> <img src="https://img-blog.csdnimg.cn/c80e6d373b1749578e748ad2d746c27f.png"></p>
</div>
<div class="cl-preview-section">
<p> 因为安装了git与这个工程可能不对，我们直接使用源码修改大法，直接定位到代码给删掉：<br> <img src="https://img-blog.csdnimg.cn/ce3d158b52de4ee893d2fd03282f8f43.png"><br> 直接删掉目录下的缓存文件：CMakeCache.txt，然后继续：<br> <img src="https://img-blog.csdnimg.cn/0281c6067a244912b014ce02b32f06c6.png"></p>
</div>
<div class="cl-preview-section">
<h2>步骤五：配置Qt的依赖环境</h2>
</div>
<div class="cl-preview-section">
<p> 麒麟系统本身自带了qt5，而我们使用了另外安装的qt5，所以依赖需要引入我们自己安装的qt5上。<br> 为了方便配置，也不影响系统我们装上cmake的gui版本：</p>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell"><span class="token function">sudo <span class="token function">apt-get <span class="token function">install cmake-gui
</span></span></span></code></pre>
</div>
<div class="cl-preview-section">
<p> <img src="https://img-blog.csdnimg.cn/f66543edd8714bc6b1b62a1127390106.png"></p>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell">cmake-gui
</code></pre>
</div>
<div class="cl-preview-section">
<p> 选择对应的路径，然后使用默认unix makefile方式配置：<br> <img src="https://img-blog.csdnimg.cn/1a85966049a74861ae18d955c394eead.png"><br> 错误如下：<br> <img src="https://img-blog.csdnimg.cn/b2e8b79814be46ad824228e9ac4bc63c.png"><br> 添加环境变量路径：<br> <img src="https://img-blog.csdnimg.cn/c2264a07f1574c928bd70fd1e3b8716d.png"><br> 继续配置成功：<br> <img src="https://img-blog.csdnimg.cn/5dc5400cf3514ced8ee143d3f1274670.png"></p>

<div class="cl-preview-section">
<h2>步骤七：编译make</h2>
</div>
<div class="cl-preview-section">
<p> 切入build目录，并且使用make命令即可：</p>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell"><span class="token function">make

</div>
<div class="cl-preview-section">
<h2>步骤八：安装到系统目录</h2>
</div>
<div class="cl-preview-section">
<p> 没有make install这个，手动移动到/usr/local/bin</p>
</div>
<div class="cl-preview-section">
<pre><code class="prism language-shell"><span class="token function">sudo <span class="token function">mv linuxdeployqt /usr/local/bin/

<h2>步骤九：测试是否编译成功</h2>
