【问题描述】：

我正在尝试使用 android NDK 构建一个 Android 项目。

我已将 NDK 添加到 QT 版本中，自动检测到构建工具包，但在运行 CMake 时出现以下错误：

Starting to parse CMake project, using: "-DCMAKE_CXX_COMPILER:STRING=/home/self/Downloads/addis/android-ndk-r17b/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android-g++", "-DCMAKE_C_COMPILER:STRING=/home/self/Downloads/addis/android-ndk-r17b/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android-gcc", "-DCMAKE_PREFIX_PATH:STRING=/home/self/Qt5.9.6/5.9.6/android_x86", "-DQT_QMAKE_EXECUTABLE:STRING=/home/self/Qt5.9.6/5.9.6/android_x86/bin/qmake".

  CMake will not be able to correctly generate this project.

我做错了什么？

编辑所以按照建议我下载了 NDK 10e ...问题似乎保持不变：

【问题讨论】：

你有什么版本的NDK？

@eyllanesc 昨天下载的最新版本。 R17b

Qt不支持最新版本的NDK，必须使用10e版本，查看文档：doc.qt.io/qt-5/androidgs.html

@eyllanesc 很有趣。但他们推荐 10e，而不是要求。这确定是原因吗？

@eyllanesc 好吧。所以请发布它作为答案:)

【参考方案1】：

Qt不支持最新版本的NDK，在docs推荐使用NDK 10e

【讨论】：

@Alex 为什么不通过 Qtcreator 使用 qmake 呢？，然后适应 cmake

@Alex 我要指出的是，首先你要确保你有正确的包，这样我们就可以丢弃一些可能的原因。

如何使用 QMake 构建现有项目 (github.com/mapsme/omim)？

mmm，所以你要编译项目，让我看看能不能编译，我告诉你我的进度。
