错误一：unable to open raise.c:Unable to read file /linux/raise.c
错误二：unable to open strlen.S:unable to read file vscode-remote?/glibc-2.27/sysdeps/aarch64/strlen.S
错误三：cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can't find starting number (in the name of file): ? in function 'icvExtractPattern'
在用vscode远程调试ubuntu上面的代码时，遇到了如下的错误，
unable to open raise.c:Unable to read file /linux/raise.c
我还以为真的是因为缺少这个文件，但是实际上出现这个错误是因为程序有bug，我的launch.json如下
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "/data/chw/firdge_3_location/action_detect_api/dt_demo",
"args": [ ],
"stopAtEntry": false,
"cwd": "${fileDirname}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": false
}
]
},
]
}这时候实际上如果不用vscode调试，直接在命令行运行 ./de_demo会发现有段错误，这是因为少了参数，如果运行 ./dt_demo test.avi就不在报错，于是修改launch.json，增加参数。

},
]
}?同样的还有一次遇到了上面的错误，这个错误也不用通过去创建strlen.S去解决。出现这个错误也是因为我的可执行程序运行出错，修改完bug之后就好了。
原来的代码是
cv::VideoCapture cap;
cap.open("./test.avi");修改为下面的代码就好了
cv::VideoCapture cap;
cap.open("./test001.avi");如果文件名不带数字，那么直接命令行运行是不报错的，但是调试的时候就报错。?
有些时候vscode调试出错，可能不是软件配置的问题，而是你的程序有错误。
