使用CMake,Clang和Ninja在Windows上构建c ++项目

Question

我目前在Windows上安装了cmake,clang和ninja.我正在尝试使用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看起来像这样:

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.

在命令行上我运行这个:cmake -G Ninja ..我得到以下错误:

-- The C compiler identification is Clang 3.5.0
clang.exe: error: no such file or directory: '/nologo'
clang.exe: error: no such file or directory: '/showIncludes'
-- The CXX compiler identification is Clang 3.5.0
clang.exe: error: no such file or directory: '/nologo'
clang.exe: error: no such file or directory: '/showIncludes'

该CMakeError.log文件如下所示:

看来cmake的试图测试与Windows选项铛/nologo和/showIncludes.我无法弄清楚如何告诉cmake传递正确的参数.

FWIW我正在运行64位Windows 7

编辑:

所以我浏览了内置的cmake文件,发现该CMakeClDeps.cmake文件是添加/nologo /showIncludes选项的罪魁祸首.看来如果我将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那些集合中的行,MSVC_C_ARCHITECTURE_ID然后再次尝试我得到以下错误:

-- The C compiler identification is Clang 3.5.0
-- The CXX compiler identification is Clang 3.5.0
-- Check for working C compiler using: Ninja

Answer 1

不知道它是否有用,但我有同样的错误.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,在构建目录中执行以下操作:

1. 加载相关的vcvarsXX.bat文件(例如"<Your Visual Studio location>\VC\vcvarsall.bat" x86)
2. 将CC和CXX都设置为clang-cl(而不是clang和clang++)
3. 跑 cmake -G Ninja <project>
4. 跑 cmake --build .

Answer 2

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

CMake 仍然认为 clang 是一个 Visual Studio 编译器，因此在CMakeDetermineCompilerId.cmake文件中有一行如下所示：

set(MSVC_${lang}_ARCHITECTURE_ID "${ARCHITECTURE_ID}")

我把它改成了这样

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。
