VS Code (Ubuntu) - miDebuggerPath is invalid.

[paxth]

Type: Debugger

When I try to use my debugger, I get the error showing:
Unable to start debugging. The value of miDebuggerPath is invalid.

• OS and Version: Ubuntu 20.04 LTS
• VS Code Version: 1.45.1
• C/C++ Extension Version: 0.28.0
• Other extensions you installed (and if the issue persists after disabling them): C++ Intellisense 0.2.2

Here is my launch.json

Any idea how do i fix it?

Does /usr/bin/lldb-mi exist?

[paxth]

I cant find that. Does that mean it's missing?

It hit the same issue with MIMode "gdb" -- installing gdb fixed it.

@paxth Are you looking to use clang/lldb for build and debugging on Ubuntu 20.04 LTS? You will need to downgrade to clang/lldb 9 in order to get lldb-mi.

lldb-mi has been removed from lldb and now Ubuntu will not build it independently and ship it: See #5415

If you can switch to g++/gdb, that will work in Linux scenarios.

 "MIMode": "gdb",
 . . .
  "preLaunchTask": "shell: g++ build active file",
            "miDebuggerPath": "/usr/bin/gdb"

this works for me...

Do i need to compile using gcc now or can i use clang too?

[sean-mcmanus]

@paxth Debugging clang-built binaries with gdb works for me on Linux...that is with gcc's libstdc++ though and not LLVM's libc++ (not sure if that matters or if there are other special cases).

Thanks guys, got it working!
