## Obtaining the debug Hyprland coredump
In very rare cases, the normal coredump would not be enough.
If that's the case, you could try obtaining the debug coredump.
A debug coredump provides more information for debugging and may speed up the process of fixing the bug.
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)
> Note: The config file used will be `hyprlandd.conf` instead of `hyprland.conf`
2. Reproduce the crash in debug mode.
3. `env DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" coredumpctl debug [PID]`(see section above)
4. Wait until the `(gdb)` appears
5. If gdb asks you `press y to continue without paging?` Type `y`
6. `bt -full`
7. copy the output of the command and provide that.
2. `cd ~`
3. For your own convenience, launch Hyprland from a tty with the envvar `ASAN_OPTIONS="log_path=asan.log"`:
- If using a wrapper, add `export ASAN_OPTIONS="log_path=asan.log"` in a separate line before the `exec Hyprland` line.
- If launching straight from the tty, execute `ASAN_OPTIONS="log_path=asan.log" ~/path/to/Hyprland`
4. Reproduce the crash. Hyprland should instantly close.
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.
