Steps to reproduce#
我参照这篇文章配置第一个opencv项目-ubuntu22.04 OpenCV4.6.0(c++)环境配置 问题出现在编译运行的地方
cd build
cmake ..
make
./demo # 执行
demo.cpp
#include<opencv2/opencv.hpp>
#include <opencv2/highgui.hpp>
#include<iostream>
using namespace std;
using namespace cv;
Mat src;
int main(int argc, char ** argv)
{
src = imread("/home/ming/PROJECT/digital/test.jpg");//这里是你的图片
if (src.empty())
{
cout << "没有读取到图像" << endl;
return -1;
}
imshow("hello", src);
waitKey(0);
return 0;
}
CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project( digital )
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable( demo src/demo.cpp )
target_link_libraries( demo ${OpenCV_LIBS} )
Reason and solutions#
- vscode installed by snap
一般是因为使用了snap安装的vscode，特别是使用鱼香一键安装命令。
当时是因为安装ros2，想顺便将vscode这些安装了，使用了一键安装。 - 解决办法
- 卸载当前的vscode 卸载命令
sudo snap remove code- 安装官方版本
选择对应的安装，我这里是选择.deb
安装命令
sudo apt install <file>.deb
最后重新运行./demo即可
