Unable to start debugging : The value of miDebuggerPath is invalid - visual-studio

Question

I recently started working on vscode. I wanted to debug my C code. But the moment I am launching the debugger getting Error : Unable to start debugging. The value of miDebuggerPath is invalid.
I have my gdb installed on wsl . It's path is /usr/bin/gdb. I have copied same path to launch.json in miDebuggerPath.
Here is my 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
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/bin/main",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": true,
"MIMode": "gdb",
"miDebuggerPath": "/usr/bin/gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
}
]
}
It should not throw the error and I should able to launch my debugger.

Answer 1

So this happened to me on WSL-Ubuntu. In my case gdb was broken because of unmet dependencies. Took a while to fix but once I reinstalled gdb properly in my WSL-Ubuntu, I finally got it working.
Installing gdb can be done on shell as
sudo apt-get install gdb
There can be multiple reasons why it could end up as broken, but once you fix gdb, vscode-debugging should be running. At the very least, you won't see that error popping.

I had the same problem, my solution was:
1. Change this section in launch.json
"miDebuggerPath": "/usr/bin/gdb",
for:
"miDebuggerPath": "C:/MinGW/bin/gdb.exe",
2. Do you need to install in your PC MinGW, this is the link:
https://osdn.net/projects/mingw/downloads/68260/mingw-get-setup.exe/
3. Next, open the MinGW then you install in the URL "C:/MinGW/bin" the gdb (select)
mingw32-gdb-bin
4. Enjoy the vs-code

Answer 3

it should be
"miDebuggerPath": "/usr/bin/gdbus",

Answer 4

If you're running under WSL, you should check where gdb is in your current distro to set your "miDebuggerPath" using
whereis gdb
in my case it was in
/usr/bin/gdb
but it could be somewhere else, that depends on what Linux distribution are you using with WSL

Answer 5

Could you try this:
sudo apt install binfmt-support
I am using VcXsrv, and this fixed all my installation problems, including chrome and GNU C++.

Answer 6

i had a similar problem ,this fixed. WINDOWS 10
QUICK ANSWER : try
1)C:\your compiler\bin\gdb.exe (paste your compiler path )
or
2)C:\TDM-GCC-32\bin\gdb32.exe for 32 bit compiler .(in my case)
(i tried to use opengl GLFW glad with 32bit tdm-gcc c++ compiler , i used a repo from OpenGL C++ template by vkphillia
but when i tried to run it in vs code using "run without debugging " option ,it showed the error "Unable to start debugging : The value of miDebuggerPath is invalid",
i copied my tdm_gcc compiler's bin path in midebugger path and it was like this ,
C:\TDM-GCC-32\bin\gdb.exe , but it did not remove the error then i checked for the gdb.exe application in my tdm gcc compiler bin where i noticed that there was no gdb.exe but a gdb32.exe file

Answer 7

I had the similar problem, running on linux.
Installing gdb fixed it.
