KDevelop debug give errors on a fresh ArchLinux install

I create new project and press debug, configured new launcher correctly, but i get this error:

Could not start debugger.
Could not run 'lldb-mi'. Make sure that the path name is specified correctly.

I have installed these packages too but result is same:
cmake gcc clang gdb lldb clazy cppcheck astyle ctags meson ninja

KDevelop 5.10.221201
ArchLinux is installed and updated on 2023-01-20
LXQt desktop with openbox and sddm
Kernel 6.1

Re: KDevelop debug give errors on a fresh ArchLinux install

It seems lldb-mi was part of the llvm/lldb project but has been moved out of it.
https://lists.llvm.org/pipermail/lldb-d … 15357.html

There's no lldb-mi pacakge in repos, but aur has https://aur.archlinux.org/packages/lldb-mi-git .
You'll have to build it yourself, check https://wiki.archlinux.org/title/Arch_User_Repository incase you're not familiar with using aur packages.

It will not work anyway since kdevelop lldb support requires python2

Re: KDevelop debug give errors on a fresh ArchLinux install

it seems, to be able to choose gdb, okteta should be installed, after that, i was able to select gdb instead of lldb, then debugging worked, but we can't choose lldb anymore? i hope it will be fixed soon.
i think kdevelop would need to give more informative errors like, "okteta is not found and in order to use gdb, okteta needs to be installed" etc. because i am new to kdevelop and i don't know about details on how it's supposed to work in default settings.

On archlinux it's a good idea to use pacman -Qi pkgname after you installed something new.
Especially when things don't go as you expect.

Check the output of

$ pacman -Qi kdevelop

and pay attention to the list of optional dependencies and what they're needed for.
