## Obtaining the debug Hyprland coredump ## Obtaining the debug Hyprland coredump
In very rare cases, the normal coredump would not be enough. A debug coredump provides more information for debugging and may speed up the process of fixing the bug.
If that's the case, you could try obtaining the debug coredump.
Make sure you're on latest git. Run `git pull --recurse-submodules` to sync everything.
1. [Compile Hyprland with debug mode](http://wiki.hyprland.org/Contributing-and-Debugging/#build-in-debug-mode) 1. [Compile Hyprland with debug mode](http://wiki.hyprland.org/Contributing-and-Debugging/#build-in-debug-mode)

2. Reproduce the crash in debug mode. 2. `cd ~`
3. `env DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" coredumpctl debug [PID]`(see section above) 3. For your own convenience, launch Hyprland from a tty with the envvar `ASAN_OPTIONS="log_path=asan.log"`:
4. Wait until the `(gdb)` appears - If using a wrapper, add `export ASAN_OPTIONS="log_path=asan.log"` in a separate line before the `exec Hyprland` line.
5. If gdb asks you `press y to continue without paging?` Type `y` - If launching straight from the tty, execute `ASAN_OPTIONS="log_path=asan.log" ~/path/to/Hyprland`
6. `bt -full` 4. Reproduce the crash. Hyprland should instantly close.
7. copy the output of the command and provide that. 5. Check out your `~` and find a file called `asan.log.XXXXX` where `XXXXX` will be a number corresponding to the PID of the Hyprland instance that crashed.
6. That is your coredump. Attach it to your issue.
