Question

我正在尝试使用GPU = 1，OPENCV = 1，DEBUG = 1来编译YOLO。与DEBUG = 0相同的组合已成功编译，但是当我使用DEBUG = 1时，导致编译失败。

不知何故，我强烈认为它存在opencv的问题或与gdb的兼容性。

有关如何解决此问题的任何想法？

Answer 1

我向opencv报告了关于这个bug的问题并收到了一个奇怪的回复!!这是与此相关的线程： opencv3 bug related to cvRound

他们提到在使用gcc编译时，OpenCV对C的支持并不能正常工作。

因此，我暂时修改了opencv代码以使调试器工作：

我所做的改变是：将 cvRound 替换为 ceil ，将math.h包含在文件opencv2/core/types_c.h opencv2/core/core_c.h和opencv2/imgproc/imgproc_c.h /usr/local/include中权限

然后使用DEBUG = 1

成功编译了YOLO代码

或者 - 如果您不想更改openCV代码 - 您可以在其中一个yolo文件中执行类似的解决方法。例如：在detector.c的开头添加：

#include "math.h" int cvRound(double value) {return(ceil(value));}

Answer 2

关于这个问题，answer帮助解决了这个问题。

在原版yolo / darknet中，您可以看到为了调试Joseph Redmon传递不要将标记优化为gcc here：

ifeq ($(DEBUG), 1) 
OPTS=-O0 -g
endif

但是，要解决该问题，您可以使用do not conflict with debugging的优化，在Makefile中替换为：

ifeq ($(DEBUG), 1) 
OPTS=-Og -g
endif

我认为问题与优化选项完全相关。最初作者没有遇到这个问题，因为他使用的Intel Core i7-5820K具有一些特定的属性，并且不会出现冲突。

Answer 3

不知何故，我强烈感觉到opencv的问题

正确：开发人员仅使用DEBUG=0进行编译并且从不尝试DEBUG=1（反之亦然）并不罕见。无论哪个设置都是默认测试，非默认设置只有在用户报告问题时才会修复（您应该这样做）。

或与gdb的兼容性。

这与GDB没有没有。

DEBUG = 1时，YOLO'C'编译失败
