Debug page: variables cannot be displayed

[Willaaaaaaa]

Type: Bug

I am a beginner in programming so this question might be easy. That is I can't see the variables in the debug page. If you need more information, I can provide the picture posted below.

Extension version: 1.21.5 VS Code version: Code 1.92.0 (b1c0a14de1414fcdaa400695b4db1c0799bc3124, 2024-07-31T23:26:45.634Z) OS version: Windows_NT x64 10.0.22631 Modes:

This is a test cpp file.

My expectation is: VARIABLES > Locals > arr = [4] > arr[0] = "I am" arr[1] = "using" ...... But I can't see any data.

@Willaaaaaaa I'm not sure why it's not working for you. It's working for me. Does any debugging work? Do you have gdb installed? What version of g++/gdb do you have installed?

[Willaaaaaaa]

@sean-mcmanus Thanks for your attention, sir. I have install g++ and the version of g++ is as shown in the photo content. I have no idea about why I can't view variables because I'm a beginner in programming. I would greatly appreciate it if you could provide me with further assistance.

@sean-mcmanus Sir, it still don't work properly. And this is my launch.json file. Could you please help me and take a look?

@sean-mcmanus help me, please!

[sean-mcmanus]

@Willaaaaaaa Sorry, I'm not sure how to help you (I don't actually work on the debugger component, only the language service).

[sean-mcmanus]

@Willaaaaaaa You could try updating your gcc and gdb versions -- 8.1 is pretty old. You may be hitting a bug that got fixed in a newer version.

[sean-mcmanus]

@Willaaaaaaa Also, in your code, you should add #include <string> although I don't think that would cause a debugger issue.

@sean-mcmanus Hello sir. You have mentioned upgrading the g++, gdb version, which is really a very constructive and wonderful suggestion! And now I have successfully resolved the issue after the upgrade. Thank you for your continuous replies and patience!
