行人检测arm代码调试出现的问题记录

平台：嵌视科技arm板

1. /opt/gcc/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/../lib/gcc/arm-fsl-linux-gnueabi/4.6.2/../../../../arm-fsl-linux-gnueabi/include/c++/4.6.2/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the upcoming ISO C++ standard, C++0x. This support is currently experimental, and must be enabled with the -std=c++0x or -std=gnu++0x compiler options.                                                                                                                                                                  解决方案：在build_arm.sh文件中只生成到Makefile文件就结束，在makefile文件中 加入                                                          LINK            = arm-none-linux-gnueabi-g++ -lts -std=c++0x
   CXX           = arm-none-linux-gnueabi-g++ -lts -std=c++0x                                                                                                                     接着在终端输入make

2. 要用到IplImage与Mat之间的转换，如下：https://mp.youkuaiyun.com/postedit/81432133

3. error: 'createBackgroundSubtractorMOG2' was not declared in this scope                                                                                        解决方案：（原因是opencv版本不同，3和2之间的函数调用有差别，也添加了#include <opencv/cvaux.h>）                          原代码是：Ptr<BackgroundSubtractorMOG2> mog2 = createBackgroundSubtractorMOG2(History, T1, true);                                                  mog2->apply(moveFound, moveFound);                                                                                                                            现代码为：Ptr<BackgroundSubtractorMOG2> mog2 =  new BackgroundSubtractorMOG2(History, T1, true);                                                   mog2->operator()(moveFound, moveFound);

4. error: ISO C++ forbids in-class initialization of non-const static member 'flag'
   解决方案：（c++版本不同，typedef struct定义的结构体类型中不能初始化un-const static 的变量）                                            在结构体外对变量赋初值，放置的位置不同也会出现错误，本段代码中将其放置在 void match(Mat frameHSV, vector<Rect> found)。了解一下结构体的定义与使用                                                                                                                                                      

5. error: call of overloaded 'Rect_(cv::Rect_<double>&)' is ambiguous                                                                                                    解决方案：double改int型

6. 在Ubuntu16.04下的错误如下：                                                                                                                                    src/moveDetect.h: In function 'void moveDetect(cv::Mat, cv::Mat&)':
