How can I run a c++ script in debug in visual studio code?

Question

I have to run a c++ script in debug on Visual Studio Code, but I'm not able to do it. It says me that It is not able to find the file raise.c

Unable to open 'raise.c': Unable to read file (Error: File not found (/build/glibc-B9XfQf/glibc-2.28/sysdeps/unix/sysv/linux/raise.c)).

What is the problem?

Good evening Tanozar,

the problems are probably due to: - task.json

    "tasks": [
        {
            "type": "shell",
            "label": "g++ build active file",
            "command": "/usr/bin/g++",
            "args": [
                "-g",
                "${file}",
                "`pkg-config", "--cflags", "--libs", "opencv4`",
                "-lcfitsio", "-lcurl",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "-lboost_iostreams", "-lboost_system", "-lboost_filesystem", "-lpython2.7", "-lm", "-L/usr/lib/python2.7/config/", "-I/usr/include/python2.7/ ",
            ],
            "options": {
                "cwd": "/usr/bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build"
        }
    ]

this is an example of my task.json for a program that include opencv and python. Probably a first error is that the argument is not quoted. This task.json "correspond to" "g++ -Os -std=c++11 main2.cpp pkg-config --cflags --libs opencv4 -lcfitsio -lcurl -o ~/blabla/main2 -lboost_iostreams -lboost_system -lboost_filesystem -lpython2.7 -lm -L/usr/lib/python2.7/config/ -I/usr/include/python2.7/"

• launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++ build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "g++ build active file",
            "miDebuggerPath": "/usr/bin/gdb"
        }
    ]
}

you have to check this line "program": "${fileDirname}/${fileBasenameNoExtension}",

• in the program code

int main(int argc, char* argv[]) 
{
    string folder = argv[1];
}

if you write in this way you get the error "Unable to open 'raise.c': Unable to read file (Error: File not found (/build/glibc-B9XfQf/glibc-2.28/sysdeps/unix/sysv/linux/raise.c))."

string folder = "/home/.../pathofyourprogram";

in this way the problem not occured.

I hope that is useful, but i don't know the detail of this problem sorry.
