Question

64位Windows 10. Android Studio 2.3.3。

我正在尝试使用JNI将现有的C ++项目链接到Android Studio。我还试图加载所有提供的NDK-JNI示例项目。使用JNI / Cmake的所有内容都无法进行Gradle Sync，但失败并出现同样的错误：

Build command failed.

ninja: build stopped: subcommand failed.
CMake will not be able to correctly generate this project.

我安装了所有必要的SDK工具。我尝试过使用GCC而不是clang。谢谢你的帮助！

主要的错误信息是：

The system cannot find the path specified.

注意上面有些地方使用 / 作为路径分隔符：

"C:/Users/Alex/AppData/Local/Android/sdk/ndk-bundle/toolchains/llvm/prebuilt/windows-x86_64/bin/clang.exe"

并成功运行。而这一行：

C:\Users\Alex\AppData\Local\Android\sdk\ndk-bundle\toolchains\llvm\prebuilt\windows-x86_64\bin\clang.exe

好像失败了。我想问题是\。试试在IDE选项、配置文件或Makefiles中找到这个路径的定义位置，然后修改它可能会解决问题。
