Other Extensions

No response

Additional Information

I would like to know if this is a bug in gdb, or the extensions. Also it would be good if the error would contain more information on what I did wrong.

The debugger logs you provided do not match the one in the image. Could you share the logs in the scenario that you get the error?

[Omcsesz]

@WardenGnaw Here you have: error.log

[WardenGnaw]

0xc0000135 is dll not found. Do you have the C:\\cygwin64\\bin\\ in your environment path?

[Omcsesz]

@WardenGnaw No, I have c:\msys64\mingw64\bin instead.

[Omcsesz]

@WardenGnaw Any idea on what is going wrong here?

Met the same problem, have no idea to locate the root issue, feel bad.

ype "apropos word" to search for commands related to "word".

[Marcelo-Petrucelli]

I'm also facing this issue. Using VSCode. Any possible solutions or possible causes? I saw people comenting on the version of GDB, asking people to downgrade it to v9 or something...

Any suggestions?

[listenerri]

@WardenGnaw No, I have c:\msys64\mingw64\bin instead.

Put "c:\msys64\mingw64\bin;" at the very front of "PATH":

"environment": [
    {
        "name": "PATH",
        "value": "C:/msys64/mingw64/bin;${env:PATH};${command:qt-cpp.qtDir};"
    },
]

Otherwise, some DLLS might be loaded incorrectly (possibly with the same name as those in windows).
