Simple question I hope. I'm using VS Code with the C/C++ extension running on Windows for remote debugging an ARM Cortex M0 board via OpenOCD running on Linux. This all works wonderfully well, with a single exception: path characters.
The problem is the ${workspaceFolder} macro. Since VS Code is running on Windows it seems to always use \ as a path delimiter. See error picture below. Obviously hardcoding the full path using / works but makes the launch.json highly machine specific.
Anyone know how to remap the path character?
TAIA.

I'm new to VS Code. I got debugging with lldb working--for one day it worked great.
Then it began to malfunction, displaying the arrow several source statements away from the actual execution. I've tried several config changes using online guidance to no avail. I thought that maybe the debug database was messed up so I wanted to try to get it to regenerate, so moved the outDebug file aside. That did not cause it to be rebuilt.
I'm running this launch.json configuration:
{
"name": "(lldb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/rmv_ms",
"args": [],
"stopAtEntry": true,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "lldb",
"miDebuggerPath": "/usr/bin/lldb",
"preLaunchTask": "clang build active file"
},
and this in tasks.json:
"tasks": [
{
"label": "clang build active file",
"type": "shell",
"command": "/usr/bin/clang",
"args": [
"-std=c17",
"-stdlib=libc++",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${workspaceFolder}"
},
"group": { "kind":"build", "isDefault":true },
"presentation": {
// Reveal the output only if unrecognized errors occur.
"reveal": "silent"
},`enter code here`
// Use the standard MS compiler pattern to detect errors, warnings and infos
"problemMatcher": "$gcc"
}
]
The latest behavior is that when I try to start debug session it displays a menu asking me what to attach to (whatever that means) but I don't even see my program listed.
I've set up a launch.json file such that a C++ program uses an external console (so that it can receive user inputs), but when launching, VSCode simply opens a terminal window without running the program in it. If "externalConsole": true, is set to false, the program runs and can be debugged fine, just can't take inputs.
Note: No task.json file is used, CMake is used to create the executable binary.

Is it possible that VSCode doesn't have 'permission' to run an external terminal? Using on MacOS.
I have the same issue. This may not be the working answer, but hopefully it will get us farther down the correct path.
I did some digging and found the following:
VS Code Documentation mentioned that it opens an external console via lldb-mi.
A search for lldb-mi led to this post on the Apple Developer forums.
...which leads to an open source Github Repo with a build of lldb-mi
I need to read through the documentation for that build first, and then I'll give it a shot. I'll post results if it solves the issue.
I've tried to use standard (recomended ways of debugging from vscode documentation) and ran into the same issues with external terminal.
I'm also using mac and switching to CodeLLDB plugin to use LLDB for debugging helped
https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb
just follow documentation: https://github.com/vadimcn/vscode-lldb/blob/v1.8.1/MANUAL.md
But as a hint here is my working setup:
(I couldn't though make it work on windows, but I'm running windows via Parallel II, so maybe natively this plugin will work too)
tasks.json

}

just make sure you have all tools available, check by running in cli:
/usr/bin/clang --version
# and
lldb --version
good luck
I have a C file that I'm trying to debug but fail.
I'm using vscode on windows 10.
The file is quite large so I don't want to copy it here.
This is how my launch.json file looks in the .vscode folder in the folder that I'm working in:
{
// 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",

"request": "launch",
"program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",
"setupCommands": [

"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "gcc.exe build active file"
}
]
}
This is how my tasks.json looks like in the same .vscode folder:
{
"tasks": [
{
"type": "shell",
"label": "gcc.exe build active file",
"command": "C:\\MinGW\\bin\\gcc.exe",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "C:\\MinGW\\bin"
}
}
],
"version": "2.0.0"
}
when I press the "start debugging" button the screen freezes and the program stalls and then vscode crashes
I managed to find a solution, I deleted the old files, clicked debug, it wanted me to create a new configuration, chose gcc launch and then there was an option 'gcc.exe build and debug active file' , clicked it, and now everything works.
I've updated the content of the files above to how they look right now if anyone has the same issue in the future.
Anyone using Visual studio code for programming in C++? Please tell me how can i manage to do the debugging of my code in visual studio code when I'm compiling it using g++ compiler.
C++ Debugging requires a couple of steps to configure VSCode for it. Once done then C++ code can be easily debugged with F5.
I wrote a post which guides how to run and debug C/C++ files in VSCode.

For debugging multiple cpp files inside the project directory.
Your launch.json and task.json should look like this
tasks.json
{
"type": "cppbuild",
"label": "C/C++: g++.exe build active file",
"command": "C:\\MinGW\\bin\\g++.exe",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Task generated by Debugger."
}
launch.json
{
"name": "g++.exe - Build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}\\${fileBasenameNoExtension}.exe",

}
I want to ask how to debug a simple hello world output from a C++ file, on the launch file I have to put the executable but I have only created a C++ file, how to compile it, I have tried everything, please help.
{
"version": "0.1.0",
"command": "g++",
"isShellCommand": true,
// compiles and links with debugger information
"args": ["-g", "-o", "main.exe", "main.cpp"],
// without debugger information
// "args": ["-o", "hello.exe", "hello.cpp"],
"showOutput": "always"
}
Pretty old question but here's a clear explanation for anyone in future.
Issue is that the debugger was looking for a.exe but your build file will probably be named different.
Changing the values of program variable to "${workspaceFolder}\\${fileBasenameNoExtension}.exe" will fix this issue. This should be in the tasks.json and the launch.json.
This env variable takes care that the right name is substituted. Now set a breakpoint and press f5.
Further details here and here.
Here's a full preview of a working launch.json
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}\\${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": false,

NOTE: As explained here and here, you might want to set "externalConsole": true if your code needs input from user.
