编译OpenCV缺少python27_d.lib的解决方法

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

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：

在pyconfig.h中

将

#ifdef _DEBUG
#	define Py_DEBUG
#endif

#ifdef _DEBUG
//#	define Py_DEBUG
#endif

/* 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 */

/* 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 */

将

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

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