Bug Summary and Steps to Reproduce

Bug Summary: At the end of a debugging session when i step over the last statement of a program (i.e. return (0);) VS Code opens a window/tab saying "Could not load source './csu/../sysdeps/nptl/libc_start_call_main.h': 'SourceRequest' not supported.."

The window/tab title gives the path "./csu/../sysdeps/nptl/libc_start_call_main.h"

I have to click F10 or "Step over" again to end the debugging session.

Richt clicking on the tab an chose "Reveal in explorer" gives "Unable to open ./csu/../sysdeps/nptl/libc_start_call_main.h in the Windows explorer."

Steps to reproduce:

Windows 10, Linux in a WSL 2 environment.. Create a c++ project (e.g. helloworld) in Linux home folder. Debug in VS Code. Set breakpoint. Step Over (F10) until end of program. Produces the issue described above.

Can you move "logging": { "engineLogging": true, "trace": true, "traceResponse": true }, into the configuration object and share the Debug Console output here?

AlexanderRuhwinkel commented 1 year ago

Thank you @WardenGnaw for your reply.

I moved the "logging": { "engineLogging": true, "trace": true, "traceResponse": true }, into the configuration object but it doesn't give me any other output in Debug Console as without this line:

However, i tried to debug the program in a terminal (not using VS Code) and it gives me the same issue:

Apperently i am missing some sources or dev packages i guess, should have tried that beforehand.

So it is not an issue with VS Code or any extension.

Please apologize for bringing it up here.

I met the same problem on Ubuntu 22.10. Has the problem been solved?

Has this problem been solved?Hope you can get an answer, thank you

The same problem, is there an answer to the problem?

starlitsky2010 commented 4 months ago

I also met this problem. Any good suggestion?

dualrelax commented 2 months ago

Use step into to debug c language built-in functions will appear this problems.

1.Use step over to skip debug built-in functions.

2.Install glibc.

For debian

sudo apt install glibc-source

cd /usr/src/glibc

sudo tar -xvf glibc-2.36.tar.xz

In your launch.json set

"cwd": "/usr/src/glibc/glibc-2.36",

Than can use step into to debug built-in functions
