Question

我在编写代码时会收到多个Clang警告，这些警告位于名为 Boost 的Thirdparty-Library中。

我如何抑制这些警告，所以我只从我自己的代码中获得警告？

我正在使用CMake编译我的项目并尝试了不同的Clang-Options，即

-iystem /usr/include/boost

和

--system-header-prefix boost/

in

set( CMAKE_CXX_FLAGS ...

但我仍然收到与 Boost 相关的警告。

受影响的文件始终是.cpp-Files，因此CMAKE_ CXX _FLAGS应该生效。

如果我使用

激活详细的Makefile

set( CMAKE_VERBOSE_MAKEFILE 1 )

我得到以下输出。

- 系统分别设置 - system-header-prefix 选项。我也尝试了不同的Variants，因为之前的选项没有识别出效果。

-isystem /usr/include/boost -isystem boost --system-header-prefix boost/ -isystem /usr/include/boost/

但警告仍在那里

提前致谢！
