Question

我已经在Windows 7 Enterprise和10上安装了CMake 3.14.4（来自cmake-3.14.4-win64-x64.msi）和GCC 5.1.0（来自tdm64-gcc-5.1.0-2.exe）主页（64位）。

我正在尝试从cpp / hpp源文件github sources.构建一个.LIL，CMakeLists.txt引用了COTS安装中的包含目录。包含目录中的头文件具有if-else，并且CMake构建总是由于落入下面的最后一个else块而出错：

# if defined(_M_AMD64)
#  include <wchar.h>
#  if BIP_CXX11_SUPPORT
typedef char16_t CciChar;
#  else
typedef wchar_t CciChar;
#  endif
typedef __int64 CciInt;
typedef unsigned __int64 CciCount;
#  define __CCI_WINDOWS__
# else
#  error The C plugin interface for IBM Integration Bus is only available 
for 64-bit Windows x86-64 systems
#endif

步骤：

1. c:\iib-swm\build>cmake -DIIB_INSTALL_DIR=C:\Progra~1\IBM\IIB\10.0.0.12 
-G "MinGW Makefiles" ../source
-- The CXX compiler identification is GNU 5.1.0
-- Check for working CXX compiler: C:/software/C++Tools/tdm- 
gcc/bin/g++.exe
-- Check for working CXX compiler: C:/software/C++Tools/tdm- 
gcc/bin/g++.exe -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Configuring done
-- Generating done
-- Build files have been written to: C:/iib-swm/build

这是此步骤之后CMakeSystem.cmake的内容：

set(CMAKE_HOST_SYSTEM "Windows-6.1.7601")
set(CMAKE_HOST_SYSTEM_NAME "Windows")
set(CMAKE_HOST_SYSTEM_VERSION "6.1.7601")
set(CMAKE_HOST_SYSTEM_PROCESSOR "AMD64")



set(CMAKE_SYSTEM "Windows-6.1.7601")
set(CMAKE_SYSTEM_NAME "Windows")
set(CMAKE_SYSTEM_VERSION "6.1.7601")
set(CMAKE_SYSTEM_PROCESSOR "AMD64")

set(CMAKE_CROSSCOMPILING "FALSE")

set(CMAKE_SYSTEM_LOADED 1)

2. c:\iib-swm\build>cmake --build .

   -- Configuring done
   -- Generating done

我什至无法理解，即使CMake将系统处理器识别为AMD64，它也不会转换为包含.h文件中的_M_AMD64吗？我已经在网上拖曳了CMake和相关资源。尝试以管理员身份运行CMake，缩短了git项目克隆到没有运气的路径。

PS：我唯一用cpp刷的是15年前的Uni，所以如果我想念C的话，请怜悯我的领主（和女士们）。

_M_AMD64似乎特定于Visual Studio编译器。这个问题令人困惑，因为它表明CMake正在进行预处理。没有。您正在使用gcc。 gcc似乎没有实现Visual Studio特定的预处理器宏。

您将不得不更改代码以与gcc一起使用，或者使用target_compile_definitions之类的CMake命令自己定义缺少的宏。

请注意，README文件表示要使用Visual Studio 2015在Windows上进行构建。

在Windows上使用gcc / g ++进行CMake构建失败
