Debugging inside visual studio code using g++ - c++

I have had some random chances with debugging a c++ code inside visual studio code using the g++/gdb. Usually when I right-click on a file and select Build and Debug active file, it works
For the current scenario I am getting the following error :
In the Debug console I see the following error :
The program '/mnt/c/D-drive/a.out' has exited with code 1 (0x00000001).
This is my launch.json file

}
]
}
I generated the a.out file using the command g++ a1q2tester.cpp timer.cpp -std=c++0x
I have put breakpoints inside the a1q2tester.CPP file. Not sure what could be going wrong. The program just stops abruptly, and no breakpoint is triggered.

ERROR: During startup program exited with code 0xc0000135

VSCode is displaying the error message
ERROR: During startup program exited with code 0xc0000135.
When I try to debug the code. Initially MinGW installation was showing the error missing dll files, then I reinstalled MinGW, now it is no more showing any errors and the catalogue is updating properly. Restarted the system, re-added the bin folder to the Environment Path Variable.
The file is being compiled and executing properly, the Error message is displayed only while debugging
IDE: VSCode
Compiler: MinGW

Tried Fixes:
Reinstalled MinGW
Added the bin folder to the environment path variables
Restarted VSCode

How to use Intel C/C++ Classic Compiler in VSCode debugger?

I'm setting up a C environment on a Mac to implement some numerical codes for my phd.
I'm using the Intel C/C++ Classic compiler instead of the default clang.
So far, I manage to generate some debugging information evoking a command like icc -std=c17 -o code -g code.c
When I call the Run and Debug option in VSCode it show 2 options to me: C++(GDB/LLDB) and C++ (Windows). When I click the first one it shows 2 more options: C/C++: clang build and debug active file or C/C++: gcc build and debug active file. It does not show anything related to the Intel Classic Compiler. How do I use this compiler to debug with Intel C/C++ Classic compiler inside the VSCode environment?
Thanks in advance!
I think you are mixing compiling and debugging up, according to the documentation, choosing C/C++: gcc build and debug active file from the list of detected compilers on your system is just helping you to generate some configuration like this:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: g++ build active file",
"command": "/usr/bin/g++",
"args": ["-g", "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}"],
"options": {
"cwd": "/usr/bin"
},
"problemMatcher": ["$gcc"],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Task generated by Debugger."
}
]
}
If you want to debug in VSCode, what you need to do is simply adding this configuration to your launch.json:
{
// 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

gdb C++ debugger not working properly on Windows; Visual Studio Code Debugger

Overview
I have been trying to get C++ debugging to work in VS Code for quite some time now with no success.
I followed the official guide from Microsoft on setting up debugging in VS Code, but still ran into problems.
For context:

The issue
The problem branches out into two parts.
1. Firstly, I normally use git bash as my default shell in Windows, and would like to keep it that way when debugging C++. However, something that seems to be specific to it is an issue with paths. It seems that running the task here leads to the shell ignoring slashes between directories (likely because of the disparate file system interpretations). This can be seen in the following example:
> Executing task: 'C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin\g++.exe' -g C:\Users\Redact\Desktop\code\Competitive_Programming\Evaluation.cpp -o C:\Users\Redact\Desktop\code\Competitive_Programming\Evaluation.exe <
g++.exe: error: C:UsersRedactDesktopcodeCompetitive_ProgrammingEvaluation.cpp: No such file or directory
g++.exe: fatal error: no input files
compilation terminated.
The terminal process "C:\Program Files\Git\bin\bash.exe '-c', ''C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin\g++.exe' -g C:\Users\Redact\Desktop\code\Competitive_Programming\Evaluation.cpp -o C:\Users\Redact\Desktop\code\Competitive_Programming\Evaluation.exe'" terminated with exit code: 1.
2. When running the debugger with either PowerShell or cmd as the shell, pre-build works as intended and a debugging session is opened, but nothing else happens. The code doesn't stop in the main function (as the guide stated it should) nor are any breakpoints hit—indicating it's not running at all:

Any help is very much appreciated.

vscode debugging multiple files in the same folder

I am new to C++ and vscode. I know how to run the vscode debugger on a single .cc file but I don't know how to run it on a folder with multiple .h and .cc files (I have Makefile and linking is working). My current solution is to copy and paste the entire project into one file and then run the debugger which is very inefficient.
I suspect that I have to modify launch.json, so here is mine. Any tips are appreciated!

"version": "0.2.0",

Visual Studio Code WSL can't compile files in /mnt/c/OneDrive

I usually store all my programming files in One Drive so that I can access them anywhere I go. But now I need to be able to compile my c++ programs on Linux machines. So I tried using visual studio code in WSL mode but when I try to compile and debug my code I am told that it can't find any *.cpp fies in the specified location, yet the files are clearly there. If I run the compile command on my own in the ubuntu window it works just fine. When I moved the files from /mnt to my home directory everything worked fine. Why would my compile command work just fine when I use it from the ubuntu window, but now work when VS Code tries to do it? Any ideas?
Here is my task.json file and launch.json file:
