1. Don't do partial updates. If you run -Sy, you're doing things wrong.
2. Did you check the optional deps pacman told you about when you installed the package?

it was not a partial upgrade - i was sure to fully upgrade the system first - i wrote `-Sy` only for demonstration - i should have put `pacman -Syu smalltalk` to be more clear - if you try `gst-browser` yourself, i think you will easily confirm the bug

as for optdepends, only gtk3 is relevant, and it is installed - the cause of the bug is precisely as i describe in  FS#76225  - important files are missing: GTK.star and gst-gtk-3.2.92.so

Did you rebuild the package on a system with gtk2 installed?

yes, it is likely that gtk2 should be a makedepends and optdepends - i explained my experiments and proposed solutions in detail on  FS#76225 

ok to document it on this ticket, i added some GL and GTK related packages to makedepends, and several files were produced which are missing from the community binary pacakge, including the ones that should fix gst-browser and GTK-based smalltalk programs in general (/usr/share/smalltalk/GTK.star and /usr/lib/smalltalk/gst-gtk.so) - the other files add support for opengl and postgresql

makedepends+=(freeglut glew glu libepoxy libglvnd mesa) # at least one of these is necessary for openGL support
makedepends+=(gtkmm3 glade gtk2 gtksourceview3) # at least one of these is necessary for GTK support

i will leave it to the package maintainer to reduce that set; and maybe figure out what else is needed - based on the configure log, my guess is that gtk2 is the important one for gst-browser, and should probably be an optdepends also

| checking for GTK+ - version >= 2.0.0... yes (version 2.24.33)


WRT DBD-PostgreSQL.star, this is the only clue i saw

| checking for PQconnectdb in -lpq... no

i noticed it complained that SDL support would not be built - maybe SDL could be supported also

Thanks for reporting.

GTK2 has reached its end of life around 2 years ago. I tried building the package with gtk2-compat (pretends to be gtk2 at compile time, but uses gtk3 at runtime), but it did not work out.

Adding support for SDL (SDL2, if possible) and OpenGL to the package would be nice.

Thanks for communicating issues to upstream: https://lists.gnu.org/archive/html/help-smalltalk/2022-10/threads.html

One option is to add gtk2 as a dependency (but it has reached its end of life), another is to wait for a new release from upstream (but that could take years). Yet another could be to move smalltalk to AUR. I'm contemplating what the best option would be.

unfortunately, even with these changes, it still does not work - same error as reported upstrean

Object: Namespace new: 32 "<0x7f187c821c20>" error: Invalid argument
#GtkTreeModel: key not found
^CObject: Gtk error: did not understand #gtkWindowToplevel

i have an install that i compiled from source about 18 months ago, and that still works perfectly, with an up-to-date system - either i have some unspecified runtime dependency installed, or some build dependency that i had installed 18 months ago, has regressed

pragmatically speaking o/c, EOL or not, the 'gtk2' package still has 139 dependents in the arch repos - so as far as arch is concerned, it is still very much "alive" - though, some activity upstream is overdue - perhaps you would try to contact the upstream maintainer, to ask if there is any plan to migrate to GTK3

another point to consider, is that the GTK support is not strictly essential - if is only needed for GUI applications (like the GTK bindings for python, ruby, etc) - smalltalk itself would probably continue working indefinitely (ie: instead of moving it to AUR, this bug could also be fixed by disabling GTK support, so that the broken IDE is not built)

I removed /usr/bin/gst-browser from the package, disabled GTK and attempted to enable SDL1 and OpenGL.

Please test if smalltalk-3.2.91-12 is an improvement.
