Vscode-cpptools: Unable to debug with GDB

[chrmarti]

_From @Dreace on November 6, 2018 9:20_

Issue Type: Bug

Appears when debugging with GDB
ERROR: Unable to start debugging. Unexpected GDB output from command "-exec-run".
There are some codes that have this problem and some have no such problem.
This is my code

#include <bits/stdc++.h>
using namespace std;
typedef struct Line {
    double left, right;
    Line(double a, double b) {
        left = a;
        right = b;
    }
} Line;
bool cmp(Line a, Line b) {
    return a.left < b.left;
}
int main() {
    int n, m;
    int cas = 0;
    while (cin >> n >> m) {
        if (n == 0 && m == 0) {
            break;
        }
        cas++;
        int res = 1;
        vector<Line> v;
        for (int i = 0; i < n; i++) {
            int x, y;

                d = sqrt(m * m - y * y);
                v.push_back(Line(x - d, x + d));
            }

@dreace can you post what your error in the output window is? gdb is reporting an error when it tries to run your program .

@Dreace can you post what your error in the output window is? gdb is reporting an error when it tries to run your program .

This is the output of the debug window

[pieandcakes]

That tells me gdb is having a problem creating the process. If you want to see more detail from gdb, you can add "logging": { "engineLogging": true } to your launch.json and try again and see if gdb gives you more information.

If this is mingw, can you make sure the bin folder has been set as part of your path on Windows? I know with thier executables they are expecting to load libraries from that folder as part of program execution. I imagine from a regular command prompt you would get an error also trying to run the program.

I looked at the details of GDB but didn't get any useful information. I can debug other programs normally. The code mentioned earlier can be debugged normally in Dev-C++. Is it a bug?

Its gdb that has the issue, not our extension. It would be interesting to see if your program name with the spaces is causing the conflict or not.

The code mentioned earlier can be debugged normally in Dev-C++

I assume that if it can be compiled, it can be run. I'm not familiar with Dev-C++. Can you share your compilation command? Also does it work when you run the program from a regular command prompt?

[HamedMohsenavi]

HI GDB does not work

OS: Arch Linux 64bit
EXT: C/C++ IntelliSense && clang-format
VsCode-Version: 1.29.1

Video: https://ufile.io/86mnx

[pieandcakes]

@HamedMohsenavi Can you provide a log? Are you seeing the same thing in the log?

[HamedMohsenavi]

@pieandcakes It doesn't actually giving me a log.. Or maybe I just can't find it

[pieandcakes]

@HamedMohsenavi does changing your setting of externalConsole to false allow it to work?

[HamedMohsenavi]

@pieandcakes No it doesn't. it's okay with NodeJS or Python Debuggers, Only GDB doesn't work

[pieandcakes]

@HamedMohsenavi It sounds like you have the same issue as #2787. Please use that issue as the root issue. .

Hi, I'm having a similar problem. Was able to debug a C++ application for mingw just now, and suddenly got an error saying that it the targetArchitecture was missing. Set this to x64, and tried again. Now it keeps saying
ERROR: Unable to start debugging. Unexpected GDB output from command "-exec-run". No executable specified, use `target exec'.

Seemed to have lost part of the log

I hit this problem and solved it as follows:

1. Installed Cygwin64 including gcc and gdb. I did not add them to the windows path to avoid contaminating other workflows. Note that these tools apparently cannot tolerate any spaces in the paths to any files that they are debugging or compiling.
2. Created a working directory with NO SPACES in the path name:
   C:\Users\garyk\Documents\VSCode\test-break
3. Opened a Cygwin64 terminal (which DOES have gcc and gdb on its path) and ran VS code:
   "/cygdrive/C/Users/garyk/AppData/Local/Programs/Microsoft VS Code\Code.exe"
4. Opened my file C:\Users\garyk\Documents\VSCode\test-break\test-break.c in VS code and saved a workspace called test-break.code-workspace there.
5. Command Pallette->Build and Debug Active File
   Single-stepping, breakpoints, and watched variables now worked as expected.

@renebarto The issue is that when your program runs, it isn't able to find the dependent runtime .dlls that it needs that are part of your toolset (Cygwin, Mingw, etc). @gkenaley 's fix one way to resolve it because it makes sure that the lib and toolset is within the searchpath of Windows when it needs to resolve the dependencies.

[arbent]

Well, if you can build & debug in command line ,maybe you set wrong g++ path, check the task.json

[Stiffjobs]

@pieandcakes what can i do when i see this dialogue

[pieandcakes]

@Stiffjobs for some reason, gdb does not like Chinese characters in its file paths. Please rename the working directory or change the cwd setting in your launch.json to a path without those characters.

I also faced similar problem while trying to debug Cpp code on VSCode.

_ERROR: Unable to start debugging. Unexpected GDB output from command "-exec-run". During startup program exited with code 0xc0000135_

For me adding "C:\cygwin64bin" to PATH in environment variables did the trick.
Although VSCode _launch.json_ had miDebuggerPath set to "_C:\cygwin64\bin\gdb.exe_" it didn't work. Manually adding to PATH in environment variables fixed the error.

[lextrounce]

Or, in my case using mingw, I needed:
{
// add the directory which contains gdb
// to stop the 0xc0000135 error
"name": "PATH",
"value": "%PATH%;C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin"
}

@lextrounce
Amazing, it actually worked!!
Thanks!

@pieandcakes Sir, I need your help. I use cygwin's gdb in vscode, but i can't launch the debugger (mingw's gdb is OK). I'm sure environment variable setting is no problems.

this is the information debug console output: (I have already used "logging": {"engineLogging": true},)

ERROR: Unable to start debugging. Unexpected GDB output from command "-exec-run". Error creating process /usr/bin/C:\Users\Lch\Desktop\helloo/c:\Users\Lch\Desktop\helloo\aaa.exe, (error 2).
1: (1951) <--gdb-exit
1: (1966) ->^exit
1: (1979) Send Event AD7ProgramDestroyEvent

The program 'c:\Users\Lch\Desktop\helloo\aaa.exe' has exited with code 42 (0x0000002a).
1: (1992) Shell exited, stop debugging

The c++ source code is very simple:
`

include

using namespace std;
int main(void)
{
int i = 0;
cin >> i;
cout << "HelloWorld!";
return 0;
}
`

Can you give me some advice? I will appreciate it very much.

[lch2000]

@pieandcakes And it seems that I can't type into the integrated terminal when debugging (use mingw's gdb). In other words, when I control the program run to the line "scanf" or "cin", but at this time we can't type on the bottom integrated terminal. It is strange that I can type in when using external terminal. Is this because input and output console must be CMD rather than powershell?
