#opencv编译错误 #C++11特性

本文解决在Ubuntu16.04环境下使用Eclipse+CDT编译OpenCV4.0代码时遇到的编译错误，通过设置C++11特性支持，成功解决了与标准库和类型定义相关的编译问题。

文章目录

环境：Ubuntu16.04
工具：Eclipse + cdt
opencv 4.0.0

错误描述

编写好的正常代码，在Build Project过程中出现类似于“标准库”错误：

原因分析

Opencv 4.0需要C++11特性支持，所以必须对项目设置：

之后即可正常编译。

补充：如果正常gcc命令行编译出现相同错误，应使用：
g++ -c -std=c++11 -I/usr/loca/opencv4/include/opencv4 xxx.cpp
这里opencv的include路径根据各自环境调整。

今天给程序增加了几个其它库的头文件，结果编译的时候出现了一屏幕的报错，找到第一个报错的地方，提示min调用出错，像是重定义了，新增加的头文件A.h(暂时这么叫它)中的确有重新define了min， #ifndef min #define min(a,b) ((a)&lt;(b)? a:b) #endif 并且在这个头文件A.h中有使用，于是把这个地方define的min修改成其它名字编译就通过...

这个错误表明你在尝试创建 `CylindricalWarper` 和 `PaniniWarper` 对象时没有提供必要的构造参数。这些类的构造函数需要特定的参数（如缩放因子 `scale` 或投影参数 `A, B`），但你的代码中没有传递这些参数。 ###...

环境：Ubuntu 11.10 + TQ的交叉编译链4.46 + cmake-2.8.12.2-Linux-i386 + OpenCV-2.4.1配置的我就说了，网上有很多，自己去找。主要说一些错误的解决的办法。例如：我在 /usr/local/Opencv-2.4.1放Opencv源码，另外在 /usr/local下新建Opencv-arm目录存放交叉编译后的库配置好后，执行cmake-...

问题描述：ubuntu中使用QT同时编译opencv和pcl时出现如下错误： 错误原因：pcl和openc中均包含flann库产生冲突 解决办法：将flann目前更换为flann2或者其它名字，在更改目录后，其它关联引用文件也需要更改 涉及到文件如下： /opencv-410/include/opencv2/flann.hpp /opencv-410/include/opencv2/miniflann.hpp /opencv-410/include/opencv2/features2d.hpp

在VS平台下的C++项目，添加opencv的头文件失败问题的解决方法 报错：错误 1 error C1083: 无法打开包括文件: “opencv2/core.hpp”: No such file or directory 出现这种报错大概有以下几种原因，大家可以逐一排查 概括起来有以下三个方向： 1.项目属性配置是否正确 2.系统的环境变量是否配置正确 3.头文件的路径修改 将#include “opencv2/imgproc.hpp” 改为将#include"opencv2/imgproc/imgpr

安装路径上有一个opencv4这个目录，这个情况很多人都会遇到，因此在编写的c++代码中引用的头文件也需要加入opencv4这一级目录，但是我在实际操作的过程中，依赖多的时候偶尔还是会出错，可能是我那里没有搞正确。我的解决方式是把opencv2这一级目录放到include下面，也就是中间去掉了opencv4这一层目录，然后我的c++代码可以正常的编译了。在rk板子上编译了opencv库，然后opencv安装在/usr/local/include//opencv2下，

我们正在处理一个编译错误：`fatalerror:opencv2/opencv_modules.hpp:没有那个文件或目录`。根据引用[1][2][3][5]中的信息，这个问题通常是由于OpenCV的头文件路径中包含了一个额外的`opencv4`目录层，导致编译器在...
