`Error target gi-crystal failed to compile`

[auroraanna]

Describe the bug gi-crystal failed to compile because of missing dependencies that I have no idea how to install:

To Reproduce Steps to reproduce the behavior:

1. shards install

Expected behavior Alls shards build and install.

Environment:

• OS: NixOS
• Install method: shards

Additional context I have a suspiscion that this is a NixOS problem. I wanted to shards install to get the libadwaita bindings for packaging Collision for nixpkgs.

Thanks for raising this issue!

I'm not familiar with nix however from the error, it seems that girepository, glib and gobject are not available. Since those depend on the environment (gi-crystal is the binding generator), I suppose this guide on packaging GNOME apps might come in handy. Also taking a look at other libadwaita nix packages might be helpful!

See: nixpkgs/pika-backup & Onto wrapGAppsHook

Oh openssl is also needed for calculating the hashes (it should be buildInputs = [ openssl ]; (?))

Some other notes on packaging:

• Please take a look at the Makefile for the build commands and configuration options (if you haven't already).
• You can set some locations using env vars just like it's done in the Makefile.
• Collision uses GSettings for keeping track of the window size and maximized state between restarts. Package maintainers can disable GSettings by passing -Ddisable_gschema. The "packaging GNOME apps" nix guide has a section for GSettings.
• Collision is currently fully tested on x86_64-linux.

Let me know if there's anything I can do from my side! I can also add a nix target on the Makefile if it makes maintaining it easier!

Yes

[auroraanna]

See: nixpkgs/pika-backup & Onto wrapGAppsHook

yeah I forgot wrapGAppsHook

[auroraanna]

I took a look at some of the .nix files for other programs with wrapGAppsHook and libadwaita but it doesn't help.

[auroraanna]

I still have no idea how to install lgirepository, libglib and libgobject. I can't find the three of them in any package manager.

[auroraanna]

I also don't know how to use the bindings for libadwaita when I have them (gi-crystal is needed for generating them?)

[auroraanna]

I solved shards install failing by installing gobject-introspection which provides the libraries. it was even mentioned on https://github.com/GeopJr/libadwaita.cr, sorry…

[auroraanna]

But there still are some error messages:

Shard "gi-crystal" may be incompatible with Crystal 1.2.2

maybe you need to up the crystal version?

[GeopJr]

All these dependencies (gobject-introspection, glib, gdk) should have been provided by wrapGAppsHook, right? It also mentions There is also [wrapGAppsHook4]{#ssec-gnome-hooks-wrapgappshook4}, which replaces GTK 3 with GTK 4.

maybe you need to up the crystal version?

Collision already "requires" (more like suggest) Crystal 1.6.0 but anything above what the shards require should work. Crystal version has to be bumped in nix (seems to be blocked https://github.com/NixOS/nixpkgs/pull/173928).

You can try with 1.2.2, it should still work as expected!

[auroraanna]

You can try with 1.2.2, it should still work as expected!

Also the binding generation?

[GeopJr]

Probably. (The above error is on the environment missing Gdk - not the binding generator).

I'm currently trying to fix the nix crystal package so 1.6.0 gets in, you can wait for that I guess. (But still 1.2.2 should still probably work)

[auroraanna]

It doesn't work. non-blocking-spawn requires >= 1.3.2, < 2.0.0

[auroraanna]

thanks for trying to update the crystal package

[GeopJr]

It doesn't work. non-blocking-spawn requires >= 1.3.2, < 2.0.0

Try passing --ignore-crystal-version on shards install, if that doesn't work, I can go change the shard requirements as that's mine.

[auroraanna]

gettext also requires 1.3.2

[GeopJr]

Also mine, it should work on 1.2.2.

[auroraanna]

Not sure if it's a good idea for you to set down the requirements. Do your programs have no issues with lower versions?

[auroraanna]

I think we should wait for the crystal nixpkgs update instead of trying to make this fit.

[GeopJr]

I agree on waiting, however they should still work. There haven't been that many breaking changes >= 1.0.0. The only reason these shards (including the ones I maintain) have that requirement is that the crystal tool that initializes a new project automatically sets it to the current one.
