问题一：

我正在使用 Windows 10 家庭版。我已经安装了 Qt6、Android Studio 2019 和 Visual Studio 2019。在安装 Visual Studio 2019 之前，Qt6 工作正常，但是由于我已经安装了 Visual Studio 2019，现在 Qt6 中有所有 Android 6.0.0 Clang 套件的重复编译器（请看截图）。有人可以告诉我如何删除重复的吗？删除按钮全部变灰。为什么 Qt6 会自动检测多个相同的编译器？

Auto-Detect 下的重复编译器是：

  • Android Qt 6.0.0 Clang arm64-v8a
  • Android Qt 6.0.0 Clang armeabi-v7a
  • 安卓 Qt 6.0.0 Clang x86
  • Android Qt 6.0.0 Clang x86_64

Qt6 自动检测到三个相同的实例，所有这些实例的删除选项都是灰色的。

重复的编译器

无法删除重复的编译器（灰显）

问题2：

打开一个项目示例（即Coffee machine，Qt6安装自带的默认示例项目）后，在Qt6的General Messages (Alt + 6)中显示如下：

2021-01-12T18:19:28 Clang Code Model: Error: The clangbackend executable "C:\Qt\Tools\QtCreator\bin\clangbackend.exe" could not be started (timeout after 10000ms).

有人可以解释发生了什么，我应该怎么做才能纠正这些错误？到目前为止，我无法通过谷歌搜索找到任何答案。有没有人遇到过类似的问题？

我遇到了同样的问题。它发生在手动或通过 Android Studio 删除 NDK 版本之后。由于 Qt 需要为每个 Qt 版本提供特定的 Ndk 版本（此处的表格），因此您必须通过 Qt 选项工具重新安装 NDK。这个过程奇怪地添加了另一个自动检测工具包，并且不会覆盖旧的工具包。

解决方案是从profiles.xml. 您可以在以下位置轻松找到它：

C:\Users\**current_user**\AppData\Roaming\QtProject\qtcreator

为了决定删除哪一个，我这样做了：

  1. 检查编译器和调试器。如您所见，第二个将工作，因为 android 调试器和编译器配置了相关的 NDK。（一般其他人使用windows cdb调试器和i686编译器）在此处输入图像描述

  2. 更改其他套件的名称，警告信号将消失：在此处输入图像描述

  3. 在profiles.xml 中找到配置文件

<value type="QString" key="PE.Profile.Name">Android Qt %{Qt:Version} Clang Multi-Abi--delete this</value> 并删除整个数据标签

  1. 重命名profiles.xml 中的数据标签<variable>，如Profile.0、Profile.1。

  2. 不要忘记<variable>Profile.count</variable>根据您的套件数量更改标签。

干杯!
