Subject: Cambalache: GTK 4 projects don't work

[Message part 1 (text/plain, inline)]

Hi, this is using Cambalache 0.10.3 on Guix System (guix 77e768a).

The problem seems limited to GTK 4 projects. GTK 3 worked for me.


STEPS TO REPRODUCE

1. Launch Cambalache
2. Create a new GTK 4 project

2.1. Click "Create a new project" button
2.3. Add project name (e.g. test)
2.4. Choose location
2.5. Select Gtk 4 as Toolkit target
2.6. Add UI file name (e.g. window.ui)
2.7. Click "Create" button


EXPECTED RESULT

☑ The workspace is loaded  

☑ Clicking Toplevel → GtkApplicationWindow add a new app window to the workspace  



UNEXPECTED RESULT

☒ The workspace loads with an error:

~~~
Workspace process error
Stopping auto restart
~~~

☒ I can't add any GUI component to the workspace. Clicking Toplevel → GtkApplicationWindow adds the window to the project tree but not to the workspace  



ADDITIONAL INFORMATION

Starting Cambalache from a terminal and following the steps to reproduce I can see the following error:

~~~

Rather than cambalche being broken, this appears to be a broken gtk. 
You may want to try repairing it using `guix build --repair'.  Note,
that this probably won't work if it's a grafted store item.

Cheers

Hi Liliana,

Oh, yeah, it seems that was it (I don't understand why gtk was broken though...). I'm closing this issue.

For what it's worth, I ran

sudo guix build --repair gtk
/gnu/store/98rk525gszggbdyqk4g1xr48p6l9jzvz-gtk-4.8.0-bin
/gnu/store/1n80vbzzz512wbzzpy1f0vxm52cjw86j-gtk-4.8.0-doc
/gnu/store/61a5y8h4cm16b8pfxdd6y5xlbxm0rcpr-gtk-4.8.0

After that Cambalache didn't even start. I rebooted the system and launching Cambalache resulted in the same workspace error. Then launched Cambalache in a container:

guix shell -C cambalache -E "^DISPLAY$" -E "^XAUTHORITY$" --expose="$XAUTHORITY" --expose=/tmp/.X11-unix/ --expose=$HOME/.Xauthority --expose=/etc/machine-id --expose=/dev/dri/card0 --expose=$HOME/Descargas --expose=/tmp/dbus-sLdbO2N5m6

It worked without errors. Then left the container, tried launching Cambalache from my user profile again and it worked without errors too (confused).

Thanks, Liliana, and sorry for the noise :)
