@vaxerski , I'm still getting a SIGSEGV error with the latest code. Cloned the repo and ran make all to build the binary.
Getting this error:

./build/hyprpicker
fish: Job 1, './build/hyprpicker' terminated by signal SIGSEGV (Address boundary error)

Some debug logs (do let me know if anything else would help):

can you try from head? b6130e3 fixed this IIRC.

Sorry if this sounds dumb but because I downloaded a pre-built package from the openSUSE build service I don't know how to build this properly or if I'm missing dependencies.

To build the package to be able to answer you question I did the following:

git clone https://github.com/hyprwm/hyprpicker.git
cd hyprpicker
make all

And I got this output:

Package wlroots was not found in the pkg-config search path.

errors are quite clear, missing wlroots

[RiQuY]

It works, I had to install this deps wlroots-devel wayland-protocols-devel ninja cairo-devel pango-devel libjpeg8-devel Mesa-libGLESv3-devel but the program was able to build and open. It printed the HEX value of the pixel I selected on the console.

So the problem was that your last commit is still not saved in a new release?

[vaxerski]

it's after the latest release. Yes.
