C++ c栋和x2B栋+；使用CMake、Clang和Ninja在Windows上进行项目

我目前在windows上安装了cmake、clang和ninja。我试图使用CMake生成一个忍者构建文件来编译一个非常简单的hello world程序

我的CMakeLists.txt如下所示：

cmake_minimum_required(VERSION 2.8)
project(test_project)
add_executable(main main.cpp)

main.cpp

是一个简单的hello world程序

在命令行上，我运行了以下命令：

cmake-G Ninja..

，得到了以下错误：

似乎cmake正在尝试使用windows选项

/nologo

和

/showIncludes

测试clang。我不知道如何告诉cmake传递正确的参数

FWIW我正在运行64位Windows7

编辑：

因此，我查看了内置的cmake文件，发现

CMakeClDeps.cmake

文件是添加

/nologo/showIncludes

选项的罪魁祸首。似乎如果我将Clang设置为编译器，那么cmake认为visual studio是编译器（它将MSVC_C_ARCHITECTURE_ID设置为x86）

我删除了

CMakeDetermineCompilerId.cmake

中设置

MSVC\u C\u ARCHITECTURE\u ID

的行，重试后出现以下错误：

clang.exe: error: no such file or directory: '/nologo'

我收到的第二组错误是因为clang找不到链接器。我使用VisualStudio构建了clang，但当时它找不到VisualStudio链接器。我所要做的就是在VisualStudio开发控制台中运行它

CMake仍然认为clang是visual studio编译器，因此在

CMakeDetermineCompilerId.CMake

文件中有一行如下所示：

cmake_minimum_required(VERSION 2.8)
project(test_project)
add_executable(main main.cpp)

Compiling the C compiler identification source file "CMakeCCompilerId.c" failed.

set（MSVC${lang}{ARCHITECTURE\u ID“${ARCHITECTURE\u ID}”）

我把它改成这样

if (COMPILER_ID MATCHES "MSVC")
  set(MSVC_${lang}_ARCHITECTURE_ID "${ARCHITECTURE_ID}")
endif()

---

希望这不会破坏任何其他CMake功能。

不知道它是否有用，但我也有同样的错误。现在，我可以在Windows上使用clang（3.7.1）/ninja（1.6）/cmake（3.4.1）进行编译，并在生成目录中执行以下操作：

加载相关的vcvarsXX.bat文件（例如，

“\VC\vcvvarsall.bat”x86

）

将CC和CXX都设置为

clang cl

（而不是

clang

和

clang++

）

运行

cmake-G忍者

运行

cmake--build.

在cmake文件的开头，您是否可以尝试写：

remove\u definitions（/nologo）

和

remove\u definitions（/showIncludes）

？它可能会起作用，但如果确实起作用，这是一个很好的解决办法。否则，您可以查看cmakeCompilerId.c和cmakeCxCompilerId.cpp，看看是否有问题。@Shingetsu删除定义没有改变任何东西，我通过查看这些文件也没有发现任何东西。但是，我确实找到了/nologo/showIncludes选项的来源并编辑了我的问题。检查同一个文件是否设置了任何其他MSVC选项，并用clang替换它们。请注意，CMake本身并不支持clang（目前）。您可以尝试手动覆盖90%的必需选项，如本文所示：我仍然有问题-我没有将其检测为MSVC的问题。我已经设置了CMAKE_CXX_COMPILER_ID=Clang，但不知何故，它以类似于上次错误的方式失败。这在CMAKE 3.6.1上对我不起作用。我仍然会得到导致编译测试程序失败的/nologo etc标志。我看到CMAKE_determinate_编译器_ID（在CMakeDetermineCompilerId.CMAKE中）总是设置父作用域MSVC${lang}\u体系结构_ID，并且仅尝试设置在本地作用域中，但是我没有设置CMAKE_RC_编译器。您知道使用此设置生成的compile_commands.json文件是否可以提供给clang tidy工具，或者clan tidy工具是否需要clang.exe的命令行参数？抱歉，我不知道。
