如何使chamerMatching在OSX上运行? [英] How to get chamerMatching to work on OSX?
问题描述
我正在尝试使用OpenCV的chamferMatching功能在OSX上运行，但是在释放未分配对象的尝试失败时出现错误消息(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
我发现很少有类似这两个有用的帖子:
在Ubuntu上，只需从源代码编译 OpenCV 2.4.1 并使用该技巧.
这在OSX上不起作用.我还注释了Matching析构函数中的模板删除:
~Matching()
{
for (size_t i = 0; i<templates.size(); i++) {
// delete templates[i];
}
}
但没有喜悦.
我什至尝试注释掉chamfermatching.cpp中的所有delete语句，但仍然出现相同的错误.
更新我尝试使用3个不同的g ++版本(4.9、5和6)重新编译OpenCV 2.4.1，但出现链接错误.这是使用g ++ 5进行编译的示例:
g++-5 ../fs.cpp -I/Users/George/Downloads/Grouped/cv/opencv-2.4.1/build/install/include/opencv -I/Users/George/Downloads/Grouped/cv/opencv-2.4.1/build/install/include -L/Users/George/Downloads/Grouped/cv/opencv-2.4.1/build/install/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_video -lopencv_videostab -o fs

我尝试添加类似-std=c++11然后是-std=c++0x的标志，但并不高兴.
有关如何解决此问题的任何提示?
尽管有漏洞，但OSX上有一个选项可用(即使在OpenCV 2.4.13中也是如此):删除已编译的.dylib并将未编译的contrib模块添加到项目中. /p>
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包含的内容.
I'm trying to use OpenCV's chamferMatching functionality to work on OSX, but getting an error about a failed attempt at freeing objects that weren't allocated (as far as I can tell):
fs(58697,0x100b3c000) malloc: *** error for object 0x103800000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
I found few helpful posts like this two:
- chamerMatching malloc error
- debug assertion failed vc\include\vector vector iterator + offset out of range in chamferMatching Opencv
On Ubuntu, simply compiling OpenCV 2.4.1 from source and using that did the trick.
The same did not work on OSX though. I also commented out the templates deletion in the Matching destructor:
~Matching()
{
for (size_t i = 0; i<templates.size(); i++) {
// delete templates[i];
}
}
but no joy.
I even tried commenting out ALL the delete statements in chamfermatching.cpp, but I still get the same error.
Update I've tried recompiling OpenCV 2.4.1 with 3 different versions of g++: 4.9, 5 and 6, but I'm getting linking errors. Here's an example compiling with g++ 5:
g++-5 ../fs.cpp -I/Users/George/Downloads/Grouped/cv/opencv-2.4.1/build/install/include/opencv -I/Users/George/Downloads/Grouped/cv/opencv-2.4.1/build/install/include -L/Users/George/Downloads/Grouped/cv/opencv-2.4.1/build/install/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_video -lopencv_videostab -o fs

I've tried adding flags like -std=c++11 then -std=c++0x, but no joy.
Any tips on how I could get over this issue ?
Although hacky, one option worked on OSX (even with OpenCV 2.4.13): removing the compiled .dylib and adding the uncompiled contrib module to the project.
For OpenCV 2.4.1 there it was just a matter of commenting out delete statement. For OpenCV 2.4.13 I also had to comment out two cvconfig.h includes.
