Build problems (with GTK 4.10?)

[jackhill]

Hi Dino,

I recently tried to build Dino from a Guix branch with some GTK and GNOME updates. In particular, GTK has been updated from 4.8.1 to 4.10.3. That results in the following errors during the build:

/tmp/guix-build-dino-0.4.3.drv-0/dino-0.4.3/main/src/ui/util/helper.vala:180.26-180.33: error: Argument 1: Cannot convert from `unowned uint8[]' to `unowned string'
  180 |         p.load_from_data(css.data);
      |                          ^~~~~~~~  
/tmp/guix-build-dino-0.4.3.drv-0/dino-0.4.3/main/src/ui/util/helper.vala:180.9-180.34: error: 1 missing arguments for `void Gtk.CssProvider.load_from_data (string, ssize_t)'
  180 |         p.load_from_data(css.data);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~ 

Let me know what additional information might be helpful. I've attached a gzipped full build log.

Best,
Jack

This is a bug in Vala 0.56.11/0.56.12 and was fixed in 0.56.13.

Upstream issue: https://gitlab.gnome.org/GNOME/vala/-/issues/1478

Indeed, updating Vala solved it. Thanks for the information, and sorry for the noise. I've submitted a patch to have Vala updated in Guix. I'll close this issue. Thanks again!
