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'

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

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:
"VCvcvarsall.bat" x86 )clang-cl(而不是 clang 和 clang++)cmake -G Ninja cmake --build ."<Your Visual Studio location>VCvcvarsall.bat" x86)clang-cl (instead of clang and clang++)cmake -G Ninja <project>cmake --build .这篇关于使用 CMake、Clang 和 Ninja 在 Windows 上构建 C++ 项目的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持跟版网！
