glade 3.18.2 on slackware 14.1: "undefined symbol: g_type_add_instance_private"
 

Hi,
some time ago I managed to install glade 3.18.2 on Slackware 14.1 (see also py3cairo slackbuild fails and pygobject3 slackbuild fails) but since then I haven't used it, yet.
But when I start glade from a terminal window, it throws me this error message: and exits.

What's the reason for this error and how can I fix it?

I think that version of glade requires newer glib2 than what we have in Slackware 14.1
See here: http://upstream-tracker.org/compat_r...at_report.html

my suggestion is to downgrade to glade 3.8.3

Thanks for your reply, willysr.

Now I upgraded glib2 from version 2.36.4 to version 2.38.2 and the error message has changed toWhen upgrading to version 2.40.0, the error message is the same.

Glade 3.8.3 seems to work fine, but I'd also like to use a more current version.

You will need to upgrade to GTK+3-3.10 or newer to fix that problem

However, upgrading glib/gtk+3 may require you to rebuild/patch other applications depending on both libraries

Now I upgraded gtk+3 from version 3.8.2 to 3.13.1 and the error message now is: :(

Glade 3.8.3 still seems to work fine.

you have to upgrade other GTK+ related libraries as well such as pango, gdk-pixbuf, atk, gobject-introspection, and many more....
that's why it's recommended to stick with the one supplied with Slackware
