在Windows上编译C ++项目，CMake的，锵和忍者 [英] Building c++ project on Windows with CMake, Clang and Ninja

问题描述

我目前在Windows上安装CMake的，铛和忍者。我试图用CMake的生成忍者构建文件编译一个非常简单的Hello World程序。

我的CMakeLists.txt看起来是这样的：

  cmake_minimum_required（版本2.8）
项目（test_project）
add_executable（主main.cpp中）
 

的main.cpp 是一个简单的Hello World程序。

在命令行中运行此：的CMake -G忍者.. ，我得到以下错误：

看来cmake的正试图测试与Windows选项 / NOLOGO 和 / showIncludes 铛。我无法弄清楚如何告诉cmake的传递适当的参数。

FWIW我运行64位的Windows 7

编辑：

所以我通过内置的cmake的文件一看，我发现 CMakeClDeps.cmake 文件是用于添加罪魁祸首 / NOLOGO / showIncludes 选项。看来，如果我设置锵，因为编译器然后cmake的认为Visual Studio是编译器（它设置MSVC_C_ARCHITECTURE_ID到86）。

我删除了 CMakeDetermineCompilerId.cmake ，设置行 MSVC_C_ARCHITECTURE_ID ，再次尝试后，我收到以下错误：

解决方案

原来第二盘我收到是因为铛找不到链接错误。我已经建立了使用Visual Studio的叮当声，但在当时却找不到在Visual Studio连接。我所要做的就是在Visual Studio开发控制台运行它。

CMake的仍然认为是铿锵一个Visual Studio编译器，在 CMakeDetermineCompilerId.cmake 文件中有一条线，看起来像这样：

设置（MSVC _ $ {}郎_ARCHITECTURE_ID$ {ARCHITECTURE_ID}）

和我改成了这个样子

 如果（COMPILER_ID匹配MSVC）
  集（MSVC _ $ {}郎_ARCHITECTURE_ID$ {ARCHITECTURE_ID}）
万一（）
 

希望这不会破坏任何其他CMake的功能。

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.

My CMakeLists.txt looks like this:

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

main.cpp is a simple hello world program.

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'

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 I'm running 64bit Windows 7

EDIT:

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).

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

解决方案

Turns out the second set of errors I received were because clang could not find the linker. I had built clang using visual studio but at the time it couldn't find the visual studio linker. All I had to do was run it in the visual studio development console.

CMake still thinks that clang is a visual studio compiler so in the CMakeDetermineCompilerId.cmake file there is a line that looks like this:

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

and I changed it to look like this

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

Hopefully this doesn't break any other CMake functionality.
