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.
launch.json

Is there any way to fix this?

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 trying to debug the helloworld project
#include <stdio.h>
int
main (void)
{
printf ("Hello, world!\n");
return 0;
}
which is built using clang. I use vs-code to take these actions. Here is my task.json file:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: clang.exe build active file",
"command": "C:\\msys64\\mingw64\\bin\\clang.exe",

],
"options": {

},
"problemMatcher": [

}
As a build task, it works but then with launch.json to debug it seems with no progress. Here is my launch.json` file:

How to set-up debugger under vs-code with the use of clang/lldb?
It got stall within this command
PS C:\c_helloworld> & 'c:\.vscode\extensions\ms-vscode.cpptools-0.30.0-insiders5\debugAdapters\bin\WindowsDebugLauncher.exe' '--stdin=Microsoft-MIEngine-In-2oaooq4b.u01' '--stdout=Microsoft-MIEngine-Out-ojuis1aj.kfb' '--stderr=Microsoft-MIEngine-Error-tcxqgdhj.tgp' '--pid=Microsoft-MIEngine-Pid-nam4qmgr.r4y' '--dbgExe=C:\msys64\mingw64\bin\lldb.exe' '--interpreter=mi'
I'm trying to debug a main.cpp file that resides in a folder that has spaces in its filename: "Jim and the Skyscrapers".
The error message reads:
Unable to open 'Jim': File not found
And it also gives me the option of creating this "Jim" file.
The debug process works only if I rename the file to "JimAndTheSkyscrapers" so that it doesn't have any spaces.
The way i reference the path in the launch.json and c_cpp_properties.json files is by using the environment variable: ${workspaceFolder}.
As a debugger, I use cygwin's gdb.
I think the problem is: either the debugger parses filepaths in a manner that doesn't allow spaces, either it's a vs code problem. Knowing which one it is would be of great help.

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",

}
And a full preview of tasks.json.

"command": "C:\\MinGW\\bin\\g++.exe",

"group": {
"kind": "build",

},

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