问题描述
我目前在 Windows 上安装了 cmake、clang 和 ninja.我正在尝试使用 CMake 生成 ninja 构建文件来编译一个非常简单的 hello world 程序.
I currently have cmake, clang and ninja installed on windows. I am trying to use CMake to generate a ninja build file to compile a very simple hello world program.
我的 CMakeLists.txt 看起来像这样:
My CMakeLists.txt looks like this:
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.
main.cpp is a simple hello world program.
在命令行上我运行这个:cmake -G Ninja .. 并且我得到以下错误:
On the command line I run this: cmake -G Ninja .. and I get the following errors:
-- 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'

-- Check for working C compiler using: Ninja -- broken

CMakeError.log 文件如下所示:

看来 cmake 正在尝试使用 Windows 选项 /nologo 和 /showIncludes 来测试 clang.我不知道如何告诉 cmake 传递正确的参数.
It appears that cmake is trying to test clang with windows options /nologo and /showIncludes. I cannot figure out how to tell cmake to pass the proper arguments.
FWIW 我运行的是 64 位 Windows 7
FWIW I'm running 64bit Windows 7
所以我查看了内置的 cmake 文件，我发现 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).
So I looked through the built in cmake files and I found that the CMakeClDeps.cmake file was the culprit for adding the /nologo /showIncludes options. It appears that if I set Clang as the compiler then cmake thinks that visual studio is the compiler (it sets MSVC_C_ARCHITECTURE_ID to x86).
我删除了 CMakeDetermineCompilerId.cmake 中设置 MSVC_C_ARCHITECTURE_ID 的行，再次尝试后，我收到以下错误:
I removed the line in CMakeDetermineCompilerId.cmake that sets MSVC_C_ARCHITECTURE_ID and after trying again I get the following errors:
-- 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

推荐答案
不知道它是否有帮助，但我遇到了同样的错误.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:
Don't know if it can be helpful but I had the same error. Now I can compile with clang(3.7.1)/ninja(1.6)/cmake(3.4.1) on Windows performing the following actions in a build directory:
- 加载相关的 vcvarsXX.bat 文件(例如
")VCvcvarsall.bat" x86 - 将 CC 和 CXX 设置为
clang-cl(而不是clang和clang++) - 运行
cmake -G Ninja - 运行
cmake --build .
- load the relevant vcvarsXX.bat file (e.g.
"<Your Visual Studio location>VCvcvarsall.bat" x86) - set both CC and CXX to
clang-cl(instead ofclangandclang++) - run
cmake -G Ninja <project> - run
cmake --build .
