Ubantu 20.04安装cvsba make时报错：CV_TERMCRIT_ITER was not declared in this scope

error: ‘CV_TERMCRIT_ITER’ was not declared in this scope
   49 |   cv::TermCriteria criteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 150, 1e-10);

error: ‘CV_TERMCRIT_EPS’ was not declared in this scope
   49 |   cv::TermCriteria criteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 150, 1e-10);

安装cvsba遇到了CV_TERMCRIT_ITER 和 CV_TERMCRIT_EPS报错

接下来一步一步分析找到原因，如果要直接看结果可以跳到文末

1.报错的代码在：/cvsba/utils/test_cvsba.cpp里的49行：

cv::TermCriteria criteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 150, 1e-10);

2.一般是头文件的问题，test_cvsba.cpp里包含头文件有

#include "cvsba.h"
#include "readparams.h"

3.我们找到这两个头文件所在的位置：

sudo find / -name "*cvsba*"
sudo find / -name "*readparams*"

4.找到了文件所在位置：

cvsba-1.0.0/src/cvsba.h 
cvsba-1.0.0/utils/readparams.h

5.使用gedit 打开cvsba.h

sudo gedit cvsba.h

6.在cvsba.h里面尝试用ctrl+F找到CV_TERMCRIT_ITER，发现没有这个关键词

7.再打开readparams.h，也找不到

8.cvsba.h所包含的头文件

#include 
#include 
#include 

9.core.hpp有两个来源：Opencv的Release 和 Debug，猜测会不会是因为路径没有指明造成的

/usr/local/OpenCV/Release/include/opencv4/opencv2/core/core.hpp
/usr/local/OpenCV/Debug/include/opencv4/opencv2/core/core.hpp

尝试将头文件里面改为#include让指定更加明确，但并没有效果

10.将每一个头文件打开，找到里面都有木有关键词：CV_TERMCRIT_ITER

11.最后尝试直接屏蔽这两个关键词所在的语句

// cv::TermCriteria criteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 150, 1e-10);

然后make成功了

总结：

1.根据报错代码找到报错的test_cvsba.cpp文件

/home/chen/下载/cvsba-1.0.0/utils/test_cvsba.cpp:49:46: error: ‘CV_TERMCRIT_EPS’ was not declared in this scope
   49 |   cv::TermCriteria criteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 150, 1e-10);

2.用gedit编辑它

sudo gedit test_cvsba.cpp

3.打开test_cvsba.cpp后，将这一行注释掉

// cv::TermCriteria criteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 150, 1e-10);

4.重新make后就可以正常运行了
