## Getting a debug stacktrace
Debug stacktraces provide useful info on why a program crashed. To get proper
stacktraces from Hyprland, make sure it was [built in debug mode](#build-in-debug-mode).
After a crash, perform the following steps:
```sh
nix shell nixpkgs#gdb # get gdb temporarily
coredumpctl # check the PID of the recent crash
coredumpctl debug <PID> # using the PID found in the previous step
```
The rest of the process is the same as
[here](../../Crashes-and-Bugs#obtaining-a-debug-stacktrace), from step 3 onwards.
## Manual building
Nix works differently than other build systems, so it has its own abstractions
