[HELP] How does one debug with gdb?

[ghost]

When debugging with gdb, it's not clear how to call functions of gtk objects.

Take this for example

gtk3-rs/examples/clock/main.rs

Line 19 in 8b57ba7

label.set_text(&time);

Adding the line println!("Time from label: {}", label.text().as_str()); below it works. However a breakpoint there with gdb fails to yield a string in the console

(gdb) print label.text().as_str()
Could not find function named 'gtk::auto::label::Label::text'
(gdb) print gtk::auto::label::LabelExt::text(label)
No symbol 'gtk::auto::label::LabelExt::text' in current context

Looking at label itself doesn't help either as I don't know how to call the functions I want from inner or pointer

(gdb) print label
$1 = gtk::auto::label::Label (glib::object::ObjectRef {inner: core::ptr::non_null::NonNull<gobject_sys::GObject> {pointer: 0x55555584f7f0}})

How do I use gdb with gtk-rs?

[sdroege]

That's a general Rust question, nothing really to do with gtk-rs or gtk. Can you ask that on https://users.rust-lang.org and link your question from here?

You're right. I looked into it and it's a rustc issue rust-lang/rust#1563 + rust-lang/rust#33014 . gdb has a corresponding bug.

Now I'm curious how debugging is done in rust...
