Debugger error: could not launch terminal for debugger

[derkomai]

Hi everyone. I'm using CodeLite 9.2.0 over elementary OS 0.4 Loki (based on Ubuntu 16.04) and I seem unable to make the debugger work since updated to this version of CodeLite. Even for the simplest project: I create a new project on the workspace and try to debug the Hello World basic example that is included in it. Once I launch the debugger, ColdeLite seems not to respond for several seconds and then I get the message "could not launch terminal for debugger". The code can be build and run without any issue, but not the debugger. I can even debug with gdb (version 7.11.1) from terminal.

So far I've tried enabling the debugger log with no result and checked that the -g option is added in the debug configuration as seen here: http://stackoverflow.com/questions/1271 ... n-codelite.

Anyone can point me in the right direction? Thank you.

Edit: I've also noticed that the keyboard shortcut I've assigned to "start debuger" is not working. Every other shortcut I configured work flawlessly.

Hi,

Which version were you previous using?

The common reason for this is not having a suitable terminal installed e.g. konsole or xterm. Try installing xterm if it isn't already.

Regards,

David

I'm not entirely sure but I think it was 9.1 or 9.0. But i fresh installed my OS so I downloaded the latest stable. Xterm is already installed. Any recommendation on which console should I be using in Settings->Preferences->Terminal? I've tried both Codelite built in terminal emulator and codelite_xterm.

I see, so it's more likely to be that than the CodeLite version change.

IIRC that's to do with running your program in a terminal, not debugging it.

I suspect that Loki's default terminal is one that will not work in this situation. To find out what it is, please post the output of doing, in a terminal:
sudo update-alternatives --config x-terminal-emulator

If that is not set to xterm, try following the instructions to change it. While xterm isn't my favourite terminal, it's known to work here.

I think you nailed it!
The output for "sudo update-alternatives --config x-terminal-emulator" is:

6 /usr/lib/user-specific-alternatives/user-specific-alternatives 500 modo manual

It was set as indicated. Once I set it to xterm, the debugger started working. Thank you!

I have the same problem with Kubuntu 16.04 and KDE:

I previously used the version delivered with ubuntu. After that I downloaded the weekly build today which version is 9.2.5.

Code: Select all

Using xterm helps me to start the debugger.
