QT cross-compilation of the English version
<h3>Method 2: Set up the QT compilation environment using the ARM board</h3>
<ul>
<li>
<p>**Online installation of QT</p>
<pre><code class="language-shell">apt-get install qtcreator
apt-get install qt5-default (Dependency package）
---If the qt5-default dependency package is removed from the official website, please use the following method to install the dependency.---
sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools qtcreator</code></pre>
<p>After installation, open QT. In the menu bar of the software, select Tools -> Options to open the following window.</p>
</li>
<li>
<p><strong>Add qmake</strong></p>
<pre><code class="language-shell">/usr/local/qt5.12-arm/bin/qmake</code></pre>

</li>
<li><strong>Configure the cross-compiler</strong></li>
</ul>
<p>Click the "add" button on the right to add the locations of the gcc and g++ cross-compilers. </p>
<p>If the host has crossbuild-essential-arm64 installed, the compiler will be located in /usr/bin/. </p>
<p>If a third-party cross-compiler is used, locate the installation location and add it. </p>
<p>If the target platform is Buildroot, then the compiler included in the Buildroot Qt environment package needs to be used.</p>
<pre><code class="language-shell">g++：/usr/bin/aarch64-linux-gnu-g++</code></pre>

<pre><code class="language-shell">gcc：/usr/bin/aarch64-linux-gnu-gcc</code></pre>

<p>For ease of debugging, configure Debeggers and Devices for online debugging:</p>
<ul>
<li><strong>Configure Debuggers</strong></li>
</ul>
<p>Click the "add" button on the right to add "gbd-multiarch": <code>apt install -y gdb-multiarch</code> </p>
<p>Check if /usr/bin/gdbserver exists on the target machine. If it doesn't exist, install it: <code>apt install -y gdbserver</code>. If it still doesn't exist, install it again: <code>apt install -y gdbserver</code> (This is included in Buildroot and no additional installation is required.) </p>
<p>Back to the Qt Creator on the host machine, click the "add" button on the right to add gdb</p>
<p>Select from the mainframe： gdb-multiarch : /usr/bin/gdb-multierch</p>

<ul>
<li><strong>Configure Devices</strong></li>
</ul>
<p>Set the IP and username (root) of the device. For the convenience of debugging, a static IP can be set on the device.</p>

<ul>
<li><strong>Configure Kits</strong></li>
</ul>
<p>Add the previously set configuration items to Kits.</p>
<p>If the target platform is the Ubuntu system, this step also requires adding the path of the sysroot.</p>
