Vscode Run with debugger error "Launch program *file/path* does not exist-CodePudding

I'm trying to figure out what's wrong with my complier or launch.json file. I get an error whenever i try to run a simple program in vs code. The error says, "Launch program file_path does not exist. I tried downloading different compliers and adding different paths to my system environment variables. I'm losing faith at this point.

CodePudding user response：

I think I know which one is your issue, let me show you a quick example:

I have a folder called Test, having only Test.cpp file:

Then the Test.cpp is only having this simple code:

#include <iostream>

using namespace std;

int main(){
    cout<<"Hello World!"<<endl;
    return 0;
}

To compile the code and execute it I am

VS Code is trying to execute your program with just the workspace folder and that's causing an error, you should use this value on the variable to run and debug the program without issues:

"program": "${fileDirname}\\${fileBasenameNoExtension}.exe"

${fileDirname} - the current opened file's dirname

${fileBasenameNoExtension} - the current opened file's basename with no file extension

In that way VS Code can run and debug the executable that was generated after compiling the code, in my example I opened the file called test.cpp to do the run because the executable was generated from that one. Here is the order of the folders at the end:

I recommend you to read this article with the variables for the JSON files on VS Code and this one.
