Question

我尝试使用OpenCV的倒角匹配功能来处理OSX，但是在尝试释放未分配的对象时遇到错误（据我所知）：

fs(58697,0x100b3c000) malloc: *** error for object 0x103800000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

我发现这两个有用的帖子很少：

chamerMatching malloc error
debug assertion failed vc\include\vector vector iterator + offset out of range in chamferMatching Opencv

在Ubuntu上，只需从源代码编译OpenCV 2.4.1并使用它就可以了。

但同样在OSX上也无效。我还在Matching析构函数中删除了模板删除：

~Matching()
        {
            for (size_t i = 0; i<templates.size(); i++) {
                // delete templates[i];
            }
        }

但没有快乐。

我甚至尝试在chamfermatching.cpp中注释掉所有删除语句，但我仍然遇到同样的错误。

更新我尝试使用3种不同版本的g ++重新编译OpenCV 2.4.1：4.9,5和6，但我收到链接错误。这是用g ++ 5编译的一个例子：

我尝试添加-std=c++11然后-std=c++0x等标志，但没有欢乐。

有关如何解决此问题的任何提示？

虽然hacky，一个选项适用于OSX（即使使用OpenCV 2.4.13）：删除已编译的.dylib并将未编译的contrib模块添加到项目中。

对于OpenCV 2.4.1，只需要注释掉删除语句。对于OpenCV 2.4.13，我还必须注释掉两个cvconfig.h include。

如何让chamerMatching在OSX上工作？
