Help building on Guix

[Erudition]

I'm close to getting sane-break to work on Guix. Since the dependencies are different in Guix, I basically just try to build the source, judge from the errors what deps are missing, and add them to the environment to see if it goes further. Here is what I have so far:

guix shell cmake qtmultimedia libxkbcommon layer-shell-qt vulkan-headers qtbase@6.7.2 qtwayland@6

However I'm getting a weird issue with a missing function that is supposedly in Qt::Widgets, though that module should already be provided in qtbase, and the Cmake List has a requirement check for that module that doesn't fail...

CMake Error at CMakeLists.txt:42 (qt_add_ui):

-- Configuring incomplete, errors occurred!

Can't seem to find a package that fixes it, and there's nothing online on this particular error. What could cause qt_add_ui to be unavailable?

Thank for the detailed report. I forgot to mention in README that currently Qt 6.8 is required. If Qt 6.8 is not available for you, I can try to find a backward-compatible way to build.

[AllanChain]

You can try the latest commit 3ffab99

[Erudition]

Ohh so that's what it was...
Yeah, 6.7 is as new as we've got right now.

I'll git pull and try again, thanks

[Erudition]

Yup, that worked! Continuing through the errors, I got it to build with this final list of packages, including optional support stuff:

guix shell --container make cmake gcc-toolchain  libxkbcommon layer-shell-qt vulkan-headers qtbase@6 qtmultimedia qtwayland@6 wayland pkg-config libxscrnsaver libx11

That's run in a pure isolated container, so it's the minimal set of packages. Pretty soon I'll have a complete package recipe for Guix (which works on other distros btw).

[AllanChain]

Thanks for testing with Guix, and I have added instructions in README. Closing this issue as completed.

[Erudition]

To whomever is interested: I finished a complete package recipe for Guix. I tested it on X and Wayland, Plasma and Gnome. It can be installed with

guix package --install-from-file=sane-break.scm

Where sane-break.scm is:

(use-modules (guix packages) (guix download) (guix build-system qt) (guix licenses) (gnu packages qt) (gnu packages xdisorg) (gnu packages xorg) (gnu packages kde-plasma) (gnu packages freedesktop) (gnu packages vulkan) (gnu packages gtk) (gnu packages pkg-config) (gnu packages kde-frameworks))

	(synopsis "A cross-platform break reminder designed to help you take meaningful breaks without disrupting your workflow.")
	(description
		"Most break reminder apps send notifications before the break is scheduled, but that merely informs me that a break is going to happen, rather than telling me it's happening right now. Even with a warning, when the break actually happens I'm too often deeply focused on a task. Then, the program either forces the break, interrupting my work, or I can use a 'skip' or 'postpone' button. Accepting abrupt interruption is too harsh, so I tend to click 'skip' or 'postpone'. Then, that becomes an almost instinctive habit, and before I know it, hours have passed without a single break.

		In contrast, Sane Break allows me to take ownership of when to stop and break. It starts by providing a gentle, non-intrusive reminder through a flashing window. The break officially begins as soon as I naturally pause after finishing my current task. This way, Sane Break offers the flexibility to wrap up my work and take a break on my terms, rather than forcing an abrupt interruption.

		Sane Break aims to strike a balance between respecting your workflow and ensuring you take the breaks you need.")

Note: while the gnome shell extension is installed successfully, the extension's manifest says it requires a minimum version of 45:

sane-break/packaging/linux/gnome/sane-break@allanchain.github.io/metadata.json

Line 5 in 7bdd01e

"shell-version": ["45", "46", "47"],

But the latest in Guix is currently 44 at this time of writing. Thus, Gnome won't let you enable the extension. While sane-break still "works" in this case, the break window does not cover the whole screen (just the top inch) in my experience.

GNOME Shell 45 introduced some breaking changes in extensions, and maintaining two versions of shell extensions is difficult. Maybe waiting for GNOME 45 support in Guix is the better 🙂
