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 ninja 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：

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

似乎 cmake 正在尝试使用 windows 选项/nologo和/showIncludes. 我不知道如何告诉 cmake 传递正确的参数。

FWIW 我正在运行 64 位 Windows 7

编辑：

因此，我查看了内置的 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，则 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该组中的行，MSVC_C_ARCHITECTURE_ID再次尝试后出现以下错误：

-- 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

不知道它是否有帮助，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clangand clang++）
  3. 跑cmake -G Ninja <project>
  4. 跑cmake --build .

原来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。
