xcode - 如何让 chamerMatching 在 OSX 上工作？

Question

我正在尝试使用 OpenCV 的 chamferMatching 功能在 OSX 上工作，但收到有关尝试释放未分配对象失败的错误(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

我发现很少有像这两个有用的帖子:

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

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

虽然在 OSX 上同样没有工作。我还在 Matching 析构函数中注释掉了模板删除:

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

但没有快乐。

我什至尝试注释掉 chamfermatching.cpp 中的所有删除语句，但我仍然遇到同样的错误。

更新 我已经尝试使用 3 个不同版本的 g++ 重新编译 OpenCV 2.4.1:4.9、5 和 6，但出现链接错误。这是一个使用 g++ 5 编译的示例:

我试过添加标志，例如 -std=c++11 然后是 -std=c++0x，但没有成功。

关于我如何解决这个问题的任何提示？

Answer 1

虽然很老套，但一个选项在 OSX 上有效(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，只需注释掉 delete 语句即可。对于 OpenCV 2.4.13，我还必须注释掉两个 cvconfig.h 包含。
