VS2010自行编译OpenCV2.4.4时缺少python27_d.lib的解决方法

  错误 24 error LNK1104: 无法打开文件“python27_d.lib”  C:\OpenCV\VS2013_64\modules\python\LINK opencv_python

编译环境概述:

  1、IDE:Visual Studio C++2010,debug win32;

  2、OpenCV版本:opencv-2.4.4.tar.gz(源代码);

  3、CMake版本:cmake-2.8.8-win32-x86.exe。

 方法1:

  错误的原因是系统安装有Python2.7,而默认的情况下Python是不提供python27_d.lib和python27_d.dll文件的。为了编译通过,需要在网上下载此二文件。下载地址请点击这里

  将下载的lib文件置于C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib,dll文件置于C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin,编译通过。

 方法2:

  一个妥协的方法是注释掉会使用python27_d.lib部分的代码,替换为使用python27.lib

   具体做法如下:

  在OpenCV项目的bindings中的opencv_python项目中,点击“外部依赖项”,在其中找到pyconfig.h和object.h文件,如下图所示:

  在pyconfig.h中,将

#ifdef _DEBUG  
#   define Py_DEBUG  
#endif  

  修改为:

#ifdef _DEBUG  
//# define Py_DEBUG  
#endif  

  将

/* For an MSVC DLL, we can nominate the .lib files used by extensions */  
#ifdef MS_COREDLL  
#   ifndef Py_BUILD_CORE /* not building the core - must be an ext */  
#       if defined(_MSC_VER)  
            /* So MSVC users need not specify the .lib file in 
            their Makefile (other compilers are generally 
            taken care of by distutils.) */  
#           ifdef _DEBUG  
#               pragma comment(lib,"python27_d.lib")  
#           else  
#               pragma comment(lib,"python27.lib")  
#           endif /* _DEBUG */  
#       endif /* _MSC_VER */  
#   endif /* Py_BUILD_CORE */  
#endif /* MS_COREDLL */ 

  修改为

/* For an MSVC DLL, we can nominate the .lib files used by extensions */  
#ifdef MS_COREDLL  
#   ifndef Py_BUILD_CORE /* not building the core - must be an ext */  
#       if defined(_MSC_VER)  
            /* So MSVC users need not specify the .lib file in 
            their Makefile (other compilers are generally 
            taken care of by distutils.) */  
#           ifdef _DEBUG  
#               pragma comment(lib,"python27.lib")  
#           else  
#               pragma comment(lib,"python27.lib")  
#           endif /* _DEBUG */  
#       endif /* _MSC_VER */  
#   endif /* Py_BUILD_CORE */  
#endif /* MS_COREDLL */  

  在object.h中,将

/* Py_DEBUG implies Py_TRACE_REFS. */  
#if defined(Py_DEBUG) && !defined(Py_TRACE_REFS)  
#define Py_TRACE_REFS  
#endif  

  修改为

/* Py_DEBUG implies Py_TRACE_REFS. */  
#if defined(Py_DEBUG) && !defined(Py_TRACE_REFS)  
//#define Py_TRACE_REFS  
#endif  

保存之后,再次编译就成功啦!
