为了在程序中用regex，升级了我的mingw，结果官网上的GCC版本都到6.3了，之前一直用4.8。换了编译器以后，对opencv2.4.10的引用就出了问题：undefined reference to `cv::imread(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)'，所以尝试使用新的编译器编译opencv，顺便也把opencv升级到2.4.13。

使用mingw64的32位版本编译opencv，默认配置。gcc version 6.3.0
编译过程中出错，报：
error: unrecognized command line option '-sse2'; did you mean '-msse2'?
搜索无果，在makefile中找到这一行，放在命令行中执行，发现缺少一个头文件的包含路径，加上以后重新在命令行执行，编译成功，继续make

然后出了错误：
error: '::hypot' has not been
查了此链接：
http://blog.csdn.net/a3335581/article/details/68583030
和http://stackoverflow.com/questions/28683358/error-hypot-has-not-been-declared-in-cmath-while-trying-to-embed-python
都说要在include Python前include cmath，所以在：
\opencv-2.4.13\modules\python\src2\cv2.cpp 文件中加了一句：
#if defined(_MSC_VER) && (_MSC_VER >= 1800)
// eliminating duplicated round() declaration
#define HAVE_ROUND 1
#endif
#include <cmath>
#include <Python.h>
但是不管用，通过查看错误提示：
In file included from C:/Python27/include/Python.h:8:0,
from D:\software\opencv\opencv-2.4.13\modules\python\src2\cv2.cpp:6:
C:/msys32/mingw32/include/c++/6.3.0/math.h:91:12: error: 'std::_hypot' has not been declared
using std::hypot;
^
认为应该加include math.h
所以将cmath改成：
#include <math.h>
以后，错误消除。

然后发生了错误：
libpython27.a: error adding symbols: File format not recognized
搜索说是要将libpython27.a移出C:\Python27\libs文件夹，然后将python27.dll文件放入此文件夹，然后下载gendef.exe
gendef python27.dll
dlltool --as-flags=--32 --dllname python27.dll --def python27.def --output-lib libpython27.a -m i386
创建一个正确的libpython27.a ，每一个object 都是32-bit.
然后就编译成功了。

用新的opencv做程序，结果之前存在的问题还是存在，于是白弄了
