QtCreator：是否可以调试远程GUI应用程序？ （GDB）

Question

1. 主持并定位ubuntu 16.04
2. 正在使用GDB
3. ssh工作正常，启用了X11转发 - 启动内置应用程序与GUI一起工作
4. 还创建了qtcreator中的远程linux配置，并成功用于控制台应用程序。
5. 〜/ .ssh / config包含X11Forward true

问题 - 应用失败并显示错误＆＃34;未找到显示＆＃34; 。似乎qtcreator没有使用带有标准配置的系统ssh。 另一方面，我无法在qtcreator中找到启用X11应用程序的选项

有人在qtcreattor下进行远程GUI调试吗？

有可能吗？

Answer 1

QtCreator似乎真的使用集成的SSH实现，并且不允许您自定义其选项。 除此之外，你可以解决这个问题。为此，请按以下步骤操作：

1. 使用真实SSH并使用-X选项激活到要调试的主机。您必须在整个测试期间保持此连接打开。

2. 使用例如<?php require_once('init.php'); $query="SELECT * FROM `bannerStock`"; $result = mysqli_query($db_conx, $query); $myArray=[]; while($row=mysqli_fetch_assoc($result)) { $name=$row['name']; $categorytoadd=""; if($row['Automotive']==1){$categorytoadd.=' Automotive';} if($row['Backgrounds']==1){$categorytoadd.=' Backgrounds';} if($row['Church']==1){$categorytoadd.=' Church';} if($row['Community']==1){$categorytoadd.=' Community';} if($row['Money']==1){$categorytoadd.=' Money';} if($row['Food']==1){$categorytoadd.=' Food';} if($row['Gaming']==1){$categorytoadd.=' Gaming';} if($row['Healthcare']==1){$categorytoadd.=' Healthcare';} if($row['Holidays']==1){$categorytoadd.=' Holidays';} if($row['Sports']==1){$categorytoadd.=' Sports';} if($row['Patriotic']==1){$categorytoadd.=' Patriotic';} if($row['Retail']==1){$categorytoadd.=' Retail';} if($row['Education']==1){$categorytoadd.=' Education';} if($row['Misc']==1){$categorytoadd.=' Misc';} $rowNumb=$row['id'];

3. 在QtCreator上，使用QtCreator左侧面板上的“Projects”图标打开Project属性。

4. 在套件“运行”选项中，进入“运行环境”，单击“详细信息”，这将打开一个列表，并添加变量“DISPLAY”，其值等于步骤2中显示的值

5. 现在运行您的应用程序。您的图形部分现在应该正确显示，因为它将使用其他会话转发频道。
