gdb crashes when run from VSCode

Could you try the gdb from proposed? I think it should help.

I think I found it, never mind!

Hi Michael,

Thanks for your help! I have never dealt with this bug system before. Where can I find the details of the "proposed" that you mentioned?

Thanks again,
Lowell

I attempted to install this:
   git clone -b applied/ubuntu/jammy-proposed https://git.launchpad.net/ubuntu/+source/gdb

I then downloaded and cd'd into gdb and ran

   ./configure
   make

but got this error:

Then I tried to install GMP like this, but it failed

Should I try using the lboggsAmida link instead? I'll try it.

Ok, the jammy-proposed link did not work for me -- apparently I am not set up as a developer.

I'm running on the latest ubuntu (20.10.04.1) on a thinkpad.

So I tried installing package libgmp-dev and that installed ok. However, when I tried running "make" in the gdb directory, I got a different error this time -- earlier actually.

         The spurious makeinfo call might also be the consequence of

so I tried rm -f on the gdb directory, then re-cloned it using the https link from jammy-proposed , then did ./configure and make but got the same error.

Sorry for the annoyance

The above error seemed to be some kind of documentation problem, so I tried just running
   make -k
To ignore errors and everything else make ok. However, I am not able to figure out where the gdb executable is so that I can test it before running "make install".

Here are the places that I found non-script executables:

gdb:

Is one of these the gdb executable so I can test it? Thanks

Oh yikes I'm sorry for giving you incomplete advice. These are the instructions to follow: https://wiki.ubuntu.com/Testing/EnableProposed -- no building from source required!

I have tried this but am not making much progress.

I was able to run the Software and Updates program and use the Developer Options menu to select the
pre-released updates (jammy-proposed). I then exited the updater and came back in to confirm that the red check mark was there and it was.

However, when I went to the next step, the "updates" page looks nothing like the example documentation that you gave me. Instead, I see the file attached in updater-updates-menu.png

I did try changing the "subscribed to" from "custom" to "all updates". However, when I pressed the close button at the bottom, the Sofware and Updates menu vanished from the screen as if it had crashed. When I restarted it, I could that my selection of back to "custom", and further, the red checkmark for the pre-released (jammy-proposed) was turned off.

Each time I changed one of these two fields, it crashed the updater and turned off the settings I had just made.

Is there a log I can send you that would be helpful?

Thanks,

Should I report this issue with Software and Updater not keeping the pre-released check after I try to change the Update menu to select all changes?

It would probably be best to report the crash in the "Software and Updates" tool separately against the software-properties package (https://launchpad.net/ubuntu/+source/software-properties).

In the meantime you'll want to select "Pre-released Updates" on the "Developer Options" tab at the end of the window, rather than the "Updates" tab as shown in your screenshot.

Thanks!

thanks, I set the pre-release items on the software updater, and triggered
an update. But I saw nothing about gdb in the things it was going to
update.
Without me telling it to update all packages in the "Updates" menu of
software and updates, how do I make it update the gdb?
Thanks

The update that I just made does seem to have fixed the problem that I was
having with GDB when used under VS Code.

Thanks very much for the help!

I just retested after updating using the pre-release sw setting.

the problem has been fixed.

thank you for your assistance. Please close the ticket as "fixed".

Lowell - Thank you for testing and confirming that the gdb SRU[1] fixes this!
