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!
