在MSVC2015的Windows上铿锵有力

我尝试在Windows上使用clang-tidy - 到目前为止还没有成功。

作为先决条件，我已经安装了 LLVM 3.9.1 。

我的普通编译器是 MSVC 2015 ，我的构建系统是 QBS 1.7.2 。使用QBS我生成了compile_commands.json。当然，该文件包含MSVC 2015 cl.exe标志/参数。以下是一个显示一个文件条目的摘录：

切换到作业/项目文件夹C:/some_ci_job_folder/并运行

clang-tidy -p target\build\win64-vc14-qt56x-debug src\some_component\src\foo.cpp 1>clang-tidy.txt 2>&1

给了我以下警告和一个错误：

         ^

知道为什么clang-tidy无法正确解释cl选项（默认情况下）？

好的，谷歌搜索后发现添加--driver-mode=cl可能会改善一些事情。但

clang-tidy -p target\build\win64-vc14-qt56x-debug src\some_component\src\foo.cpp -- --driver-mode=cl 1>clang-tidy.txt 2>&1

仍然给我

1 warning and 1 error generated.
Error while processing C:\some_ci_job_folder\src\some_component\src\foo.cpp.
warning: unknown argument ignored in clang-cl: '-resource-dir=C:\Programs\LLVM-3.9.1\bin\..\lib\clang\3.9.1' [clang-diagnostic-unknown-argument]

         ^

所以它不再抱怨包含路径参数，但据我所知，这些参数只是被忽略了？

BTW：我在clang-tidy内运行Developer Command Prompt for VS2015。到目前为止，我不确定这是否是必需的？

任何想法......如何解决问题，如何调试包含路径参数的评估，......？

我是Cppcheck开发人员。

clang-tidy已集成在Cppcheck GUI中。

您可以使用Cppcheck GUI在编译数据库或visual studio解决方案上运行clang-tidy。 Cppcheck GUI使用自己的编译数据库解析器，它可能与clang-tidy内置解析器的工作方式不同。

它是一个免费的开源（GPL）工具。可以在此处下载：http://cppcheck.sf.net

以下是一些屏幕截图：http://cppcheck.sf.net/clangtidy/index.html

随意尝试，如果有什么我们可以解决，请随时告诉我。

答案 1 :(得分：1)

您可以使用VS2015 / VS2017的Clang电动工具扩展，而不是直接调用clang-tidy。 直接在IDE上运行，您可以选择要激活的检查，甚至可以将自动代码修复应用到modern- *检查。
