如何在 VS 项目中禁用 clang-cl 特定警告 [英] How to disable clang-cl specific warnings in VS project

问题描述

我使用了一个 3rd 方项目，该项目会产生大量警告.我在 VS 项目属性中禁用了所有这些.有时，我切换到 LLVM clang-cl 工具集来检查来自 clang 的警告.第 3 方项目使用 clang-cl 产生如此多的警告，以至于 VS 被输出量阻塞.我知道如何禁用它们，我是通过命令行参数来实现的，例如:Wno-int-conversion -Wno-shift-op-parentheses 等.但是，当我切换回VS 工具集，所有这些用于禁用来自 clang-cl 的警告的命令行参数都变成了 MS 编译器的错误(未知的 cmd 行参数).

I use a 3rd party project, that produces huge amount of warnings. I disable all of them in VS project properties. Sometimes, I switch to LLVM clang-cl toolset to check for warnings from clang. The 3rd party project produces so many warnings with clang-cl that VS is chocking with the amount of output. I know how to disable them, I do so through command line args, for example: Wno-int-conversion -Wno-shift-op-parentheses etc. The problem, however, when I switch back to VS toolset, all of these command line params to disable warnings from clang-cl become errors (unknown cmd line args) with MS compiler.

有没有办法在同一个 VS 项目中同时使用 clang 和 VS 设置?也许，以 ClangCL 工具集为条件，这些只能添加到 clang-cl 构建中?

Is there a way to have both clang and VS settings in the same VS project? Maybe, somehow conditional on ClangCL toolset these could be added only for clang-cl builds?

推荐答案

我尝试的第一件事马上就奏效了，以防万一有人需要解决同样的问题:

The first thing I tried worked right away, in case if anybody needs to solve the same problem:

  <AdditionalOptions Condition="'$(PlatformToolset)'!='ClangCL'">/w24003 /w24005 ... %(AdditionalOptions)</AdditionalOptions>
  <AdditionalOptions Condition="'$(PlatformToolset)'=='ClangCL'">-Wno-unknown-pragmas -Wno-unused-variable ...  %(AdditionalOptions)</AdditionalOptions>

通过这种方式，在 VS 中使用 LLVM clang-cl 工具集时，只应用了 clang cpecific 命令行参数，而在使用 ms 编译器时，只应用了 ms 编译器特定的选项.

This way, with using LLVM clang-cl toolset with VS only clang cpecific command line params applies, and when using ms compiler, only ms compiler specific options are applied.
