I'm trying to debug my code and am having problems with running the build task. These are the error messages:
Starting build...

If I try debugging then I get this error message:
I'm new to VScode and really don't understand how to use these files any help would be much appreciated

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 just installed Visual Studio Code in Ubuntu 18.04 LTS based ElementaryOS 5.1 Hera, and set up the environment for C/C++. Launch.json and tasks.json look all fine but on debugging, the following errors are triggered:
gcc: error: unrecognized command line option ‘--interpreter=mi’
gcc: error: unrecognized command line option ‘--tty=/dev/pts/0’
gcc: fatal error: no input files compilation terminated.

Is there any way to fix this?
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.

"args": [],
"stopAtEntry": false,

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

}
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,
"cwd": "C:\\MinGw\\bin",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "C:\\MinGw\\bin\\gdb.exe",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
},
{
"description": "Set Disassembly Flavor to Intel",
"text": "-gdb-set disassembly-flavor intel",
"ignoreFailures": true
}
]
}
And a full preview of tasks.json.
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++.exe build active file",
"command": "C:\\MinGW\\bin\\g++.exe",
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Task generated by Debugger."
}
],
"version": "2.0.0"
NOTE: As explained here and here, you might want to set "externalConsole": true if your code needs input from user.
