gtk4 0.9.6 fails to build since ffi::GTK_DEBUG_BUILDER_TRACE is missing

[sophie-h]

I guess gtk4 0.9.6 should depend on gtk4-sys 0.9.6

[bilelmoussaoui]

actually the problem is that GTK_DEBUG_BUILDER_TRACE should be behind a v4_18 feature gate

[sophie-h]

But if you enable v4_18 in gtk4, it would still fail without gtk4-sys, right? So both are an issue?

[bilelmoussaoui]

if the version is added to upstream gtk, the feature gate is also added to the sys crate.

[sophie-h]

if the version is added to upstream gtk, the feature gate is also added to the sys crate.

So if you use gtk4/v4_18 0.9.6 it would use gtk4-sys/v4_18 0.9.5 and the constant would still be missing, right?

[sdroege]

Yes gtk4 needs to depend on the correct version of gtk4-sys

[bilelmoussaoui]

Indeed, my bad. I wonder how feasible to automate that from the workspace Cargo.toml.

Hi there. Your discussion... I do not get it, but I want to understand. I have same problem since latest gtk4 crate.

gtk4 = { version = "0.9.6", features = ["gnome_46"] }

But I resolve this problem by editing source code of gtk4 and in file gtk4-0.9.6/src/auto/flags.rs:297:36 I just replace GTK_DEBUG_BUILDER_TRACE with GTK_DEBUG_BUILDER.

Why when I do this, it is working? Why ?

Did someone named this variable wrong ? Or there is bigger problem.

What about my workaround?

Also when I use gtk4 = { version = "0.9.6", features = ["gnome_47"] } then I get 2 new errors:
