Environment

OS and version: Ubuntu 20.04
VS Code: 1.74.0
C/C++ extension: 1.13.9
GDB / LLDB version: 12.1.90

Bug Summary and Steps to Reproduce

Bug Summary:

I tried to use cppdebug to debug Ada code with VS Code. I am able to setup breakpoints, have a working registers view, but the Disassembly view does not work: I get an empty Disassembly view with a Disassembly not available message.

I have attached the full GDB logs and the launch.json configuration I have used: let me know if you need anything more!

Thank you for reporting this issue.

As this is the C/C++ extension and our expertise is with C/C++, we are looking for the community to help with this issue in the Ada language. As both use GDB to debug, it may be something in the response from GDB that difference between the languages that MIEngine is not handling.

Answer 2 · 2023-01-13T09:37:09.000Z

Ok, thanks for the feedback ;) Should I try to create an issue on the MIEngine side too?

I think this is a won't-fix, please close.

Answer 4 · 2024-07-12T21:08:11.000Z

Yes, no upvotes. We will close it.
