Can't scroll up the terminal

Can't scroll up the terminal

[crucio55]

1. Yes, I used the mouse wheel
2. Yeah, I can type in it

[rohanrhu]

Optimizing with -O3 was indeed done, and some values being optimized out is a given - but getting the tracebacks without explicitly specifying they're wanted with --verbose is less nice.

Yes, I will reduce unnecessary warnings.

With default settings, tmux's mouse setting is enabled. This means the scrollbar of the terminal may not work. Instead, we can scroll with mouse wheel.

I have some questions to understand the issue:

1. Are you trying to scroll with mouse wheel?
2. Are you able to type something on terminal even though you can't do scroll?

[rohanrhu]

1. Yes, I used the mouse wheel
2. Yeah, I can type in it

Interesting... What browser are you using?

Vivaldi

Vivaldi

It is really interesting. Can you try it on another browser? When you do scroll, is terminal cursor being moved?

Tired out Firefox, seems the same. With ctrl+b (tmux's default control key bind) i manage to scroll the terminal with the arrows and page up/down - but I can't exit that mode (exiting it is done by Esc - but in gdbfrontend it just removes focus from the terminal)

Ok. I will check it out.

I have some questions:

• What is your tmux version?
• Can you do tmux set-option mouse on and try again on the terminal?

[crucio55]

Hi, sorry for the delay!

• What is your tmux version?
• Can you do tmux set-option mouse on and try again on the terminal?

• tmux version is 2.1, though I also have 2.3a on the machine that isn't the default version for this user
• I tried with set-option mouse on in .tmux.conf, the results are the same in 2.1 - but scrolling does now work when using 2.3a!!!

Nice! It sets tmux's mouse option to on as default on startup. Must be something wrong with tmux 2.1.

Let's add a notice about minimum tmux version or buggy tmux versions to README.md.

• What is your distro? Where did you install newer tmux?
• Is there any problem now?

[crucio55]

• What is your distro? Where did you install newer tmux?

Fedora 23 (ancient indeed) - with the new tmux installed manually from source

• Is there any problem now?

Yeah, I keep getting these in the terminal:

[rohanrhu]

Yeah, I keep getting these in the terminal:

Are you using --verbose option? Actually without verbose option, you must see only gdb.error: value has been optimized out part of this. It means your code is compiled with an optimization flag (like -O3).

For debugging, you should compile your code with zero optimization and debug symbols flags: -O0 and -g.

Like this:

gcc -o app app.c -O0 -g

If you see this traceback even if you don't use --verbose, I will avoid this traceback reporting.

No, I'm not using the --verbose option.

I reduced unnecessary warnings. It will be come with v0.10, also you can get the latest revision from GIT until the release.

For tmux problem I will add a "minimum tmux version" note to README.md.

Thank you for reporting!
