在Windows上使用gcc / g ++进行CMake构建失败

Question

I've installed CMake 3.14.4 (from cmake-3.14.4-win64-x64.msi) and GCC 5.1.0 (from tdm64-gcc-5.1.0-2.exe) on Windows 7 Enterprise and 10 Home (64-bit).

I'm trying to build a .LIL from cpp/hpp source files github sources. The CMakeLists.txt refers to includes directory from the COTS install. A header file in the includes directory has this if-else and the CMake build always errors out by falling in the last else block below:

# 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

Steps:

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-

This is the content of CMakeSystem.cmake after this step:

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 .

I just can't understand that even when CMake recognizes the system processor as AMD64, it doesn't translate to _M_AMD64 in the includes .h file? I've trawled CMake and related resources on the net. Tried running CMake as admin, shortened the path in which git project was cloned to without luck.

PS: My only brush with cpp was at Uni 15 years ago, so please have mercy my lords (and ladies) if I've missed to C the obvious.

Answer 1

_M_AMD64 appears to be specific to Visual Studio compilers. The question is confusing because it suggests that CMake is doing the pre-processing. It doesn't. You are using gcc . gcc doesn't appear to implement the Visual Studio specific pre-processor macros.

You'll either have to alter the code to work with gcc or define the missing macros yourself using a CMake command like target_compile_definitions .

Be aware that the README file says to use Visual Studio 2015 for building on Windows.
