# Build in debug mode
|
|
|
|
## Required packages
|
|
|
|
`xcb` stuff, check with your local package provider.
|
|
|
|
`wayland` - of course.
|
|
|
|
*Arch*:
|
|
|
|
`yay -S gdb ninja gcc cmake libxcb xcb-proto xcb-util xcb-util-keysyms libxfixes libx11 libxcomposite xorg-xinput libxrender pixman wayland-protocols cairo pango seatd`
|
|
|
|
(If any are missing hmu)
|
|
|
|
## Recommended, CMake
|
|
|
|
Install the VSCode C/C++ and CMake Tools extensions and use that.
|
|
|
|
I've attached a [example/launch.json](https://github.com/hyprwm/Hyprland/blob/main/example/launch.json)
|
|
that you can copy to your .vscode/ folder in the repo root.
|
|
|
|
With that, you can build in debug, go to the debugging tab and hit
|
|
`(gdb) Launch`.
|
|
|
|
## Custom, CLI
|
|
|
|
`make debug`
|
|
|
|
attach and profile in your preferred way.
|
|
|
|
{{< hint >}}
|
|
For all ways, make sure to `sudo make clear` to clear any root-owned files.
|
|
Also, before the first build (or after some updates, possibly)
|
|
`sudo make config`. (If you get any `missing header file "...-protocol.h"`, you
|
|
need to `make config`.)
|
|
{{< /hint >}}
|
|
|
|
{{< hint type=warning >}}
|
|
`make config` will overwrite wlroots headers in `/usr/`,
|
|
meaning you'll be unable to build any other wlroots compositor
|
|
without a wlroots reinstall.
|
|

|
|
|
# Running
|
|
|
|
when running Hyprland in Debug mode, the config is
|
|
`~/.config/hypr/hyprlandd.conf` and the logs can be found at
|
|
`/tmp/hypr/[INSTANCE SIGNATURE]/hyprlandd.conf`.
|
|
|
|
# Logs, dumps, etc.
|
|
|
|
You can use the logs and the GDB debugger, but running Hyprland in debug compile
|
|
as a driver and using it for a while might give more insight to the more random
|
|
bugs.
|
|
|
|
When Hyprland crashes, use `coredumpctl` and then `coredumpctl info PID` to see
|
|
the dump.
|
|
|
|
I also recommend the amazing command
|
|
|
|
```sh
|
|
watch -n 0.1 "cat /tmp/hypr/$(echo HYPRLAND_INSTANCE_SIGNATURE)/hyprland.log | grep -v \"arranged\" | tail -n 40"
|
|
```
|
|
|
|
for live logs. (replace `hyprland` with `hyprlandd` for debug builds)
|
|
|
|
# Nesting Hyprland
|
|
|
|
Hyprland can run nested in a window. For that, make sure you did the following:
|
|
|
|
- built in debug
|
|
- removed ALL `exec=` and `exec-once=` keywords from your debug config
|
|
(`hyprlandd.conf`)
|
|
- set a resolution and are not using `preferred`
|
|
- made sure no keybinds overlap (I recommend using a different mod for your
|
|
keybinds altogether)
|
|
|
|
Once you launch, the display will probably be completely garbled. To fix that,
|
|
in the parent, do a `hyprctl clients` and note the size of the window. Make sure
|
|
while opening the terminal to not resize the nested window. Note that resolution
|
|
and use it down to the pixel in your `hyprlandd.conf`.
|
|
|
|
If you segfault in `shadowKeybinds`, you probably either are using the same mod
|
|
as your parent or resized the window.
