How to use GTK-rs SourceView 5 in a Relm4 app?

[gtamas]

I tried install GTK-rs SourceView lib.

 cargo add sourceview5      
    
    Updating crates.io index
      Adding sourceview5 v0.7.1 to dependencies.
             Features:
             - gtk_v4_12
             - gtk_v4_6
             - v5_10
             - v5_2
             - v5_4
             - v5_6
    Updating crates.io index
error: failed to select a version for `gtk4-sys`.
    ... required by package `gtk4 v0.6.6`
    ... which satisfies dependency `gtk = "^0.6.6"` of package `relm4-icons v0.6.0`
    ... which satisfies dependency `relm4-icons = "^0.6.0"` of package `my-app v0.1.0 (/some/path)`
versions that meet the requirements `^0.6` are: 0.6.3, 0.6.2, 0.6.0

the package `gtk4-sys` links to the native library `gtk-4`, but it conflicts with a previous package which links to `gtk-4` as well:
package `gtk4-sys v0.7.0`

Sounds like the problem comes from relm4-icons. How should I solve this? Still new to rust.

I think you need sourceview5 = "0.6" if you're using Relm4 0.6, because once one of the dependencies is updated to 0.7, they also require gtk-rs 0.7, which causes a conflict with the 0.6 dependencies. You could also use 0.7.0-beta.2 for Relm4 and 0.7.0-alpha.2 for relm4-icons if you prefer to have the other dependencies at their latest version. Relm4 0.7.0 will be out soon as stable btw.
