忍者在执行时出错

Question

我使用 Cmake 创建了 Ninja 文件。当我执行忍者文件时，它显示以下命令

myandroidcompiler.exe: error: argument unused during compilation: '-nobuiltininc'
myandroidcompiler.exe: error: argument unused during compilation: '-nostdinc++'
ninja: build stopped: subcommand failed.

我也尝试过删除这个参数。但这个错误仍然存​​在。在过去的两天里，我一直被困在这个问题上。任何帮助将不胜感激。

当我检查 CMakeoutput.log 文件时，它有以下文本：

The target system is: ANDROID64 -  - 
The host system is: Windows - 10.0.15063 - AMD64

标识标志：-c

输出是： 0

在我可以看到的构建标志中； （分号）出现在每个空格之间。是预期的吗？做错了什么？

Answer 1

添加-Qunused-arguments 编译器标志应该可以消除这些错误。 尝试将以下内容添加到您的 CMake 命令行：

cmake -DCMAKE_CXX_FLAGS=-Qunused-arguments

或者，在CMakeLists.txt：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Qunused-arguments")
