windows下编译caffe

1 准备工作

windows版caffe：https://github.com/Microsoft/caffe

VS2013（其他版本不行！！！） 

python2.7（其他版本不行！！！）

2 详细步骤

修改配置：

将  caffe-windows\windows\CommonSettings.props.example备份，并改名为CommonSettings.props

修改如下：

3 编译caffe

编译用vs2013打开.\windows\Caffe.sln 并将解决方案的配置改为release。先编译libcaffe，右键生成解决方案。如果没报错，点击项目，生成全部解决方案。如果一切顺利，则会在bulid/x64/下生成release版本或者debug版本。之后，将该版本下的caffe复制到python2.7的libs/site-pakages/目录下即可。

当然，实际操作中往往不会这么顺利。。。。下面是一些常见错误：

4 常见错误

 1  error C2220: 警告被视为错误 - 没有生成“object”文件 (..\..\src\caffe\util\math_functions.cpp)

打开VS->项目->属性->配置属性->C/C++->常规->将警告视为错误修改为“否”，重新编译就好。

2  error LNK1104: 无法打开文件“python27_d.lib”

修改编译变量debug为release  或者将python2.7下的include/pyconfig.h下的python27_d.lib修改为python27.lib

#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 */

3 找不到python27.dll

将此python27.dll文件复制到 C:\Windows\System32 下

4 __import__Pyxxx等等的错误

将python27 /include下的object.h的#define Py_TRACE_REFS注释掉

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