Mismatch between gtk3 / gtk3mm?

[Veence (Vincent)]

When trying to run inkscape-devel +gtk3, I get the following error:

dyld: lazy symbol binding failed: Symbol not found: _gtk_plug_get_type
  Referenced from: /opt/local/lib/libgtkmm-3.0.1.dylib
  Expected in: /opt/local/lib/libgtk-3.0.dylib

dyld: Symbol not found: _gtk_plug_get_type
  Referenced from: /opt/local/lib/libgtkmm-3.0.1.dylib
  Expected in: /opt/local/lib/libgtk-3.0.dylib

Which seems to suggest that the versions of gtk3 and gtkmm3 are no more synchronized. Any clue?

I can't reproduce the problem here. I'm using +x11 for gtk3, gtkmm3 and inkscape-devel +gtk3

Tell me more about your builds. Have you built gtk3 with the +quartz variant? gtk_plug_get_type is not built for +quartz. Make sure that gtkmm3 is built with the same variants as gtk3. What about gtkmm3?

I would try rebuilding gtkmm3 using the same variants as gtk3 and see if that helps.

[Veence (Vincent)]

I have built default versions of gtk3 and gtkmm3 (gtk3 defaults to +quartz, yes).

Air > port installed gtkmm3
The following ports are currently installed:
  gtkmm3 @3.10.1_1 (active)

Air > port installed gtk3
The following ports are currently installed:
  gtk3 @3.10.6_1+no_x11+quartz (active)

I see no way to build gtkmm3 with a +quartz variant:

Air > port info gtkmm3
gtkmm3 @3.10.1_1 (x11, devel)
Variants:             universal

[dbevans (David B. Evans)]

Sorry I misspoke, gtkmm3 does not have a +quartz variant.

If your gtk3 is installed with +quartz (default is +x11, so I'm assuming you have +quartz set in variants.conf) then make sure that dependents cairomm, pangomm of gtkmm are built with +quartz and then rebuild gtkmm3.

[Veence (Vincent)]

I'll check that right away. I apologize, my precedent message was a bit blunt.

[Veence (Vincent)]

They are already correct :

Air > port installed cairomm
The following ports are currently installed:
  cairomm @1.10.0_3+quartz (active)

Air > port installed pangomm
The following ports are currently installed:
  pangomm @2.34.0_2+quartz (active)

By the way, you're right, I have specified +quartz and +no_x11 in my defaults.conf…

[dbevans (David B. Evans)]

Ok, so go ahead and rebuild gtkmm3 from source.

sudo port -ns upgrade --force gtkmm3

If this works then it tends to support my operating theory that you have a gtkmm3 that was build with gtk3 +x11 (such as the one that is available from archive) rather than gtk3 +quartz (which you have on your system). If so, then I will fix the gtkmm3 port to prevent this (add +x11 +quartz variants, check variants of dependencies, etc).

[Veence (Vincent)]

Bingo! You were spot-on. Thanks a lot! I guess you're right, gtkmm3 needs some variants to avoid this mingling. Thanks again! I let you close the ticket when you're done with the update, maybe.

[dbevans (David B. Evans)]

Fix committed in r115185. This same change was already incorporated in gtkmm but somehow missed getting into gtkmm3. Thanks for your report.

[Veence (Vincent)]

You're most welcome. By the way, with gtk3, I got a lot of error messages from Inkscape

*** BUG ***
In void pixman_region32_init_rect(region_type_t *, int, int, unsigned int, unsigned int): Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

Do you get them also?

[dbevans (David B. Evans)]

No, I haven't seen this but most of the testing I've done of the +gtk3 variant has been done with +x11 and not +quartz. Note that the Inkscape developers consider this to be an experimental build, WIP. But that's why I added the +gtk3 variant -- so the developers could get more testing feedback. I suggest that you report whatever bugs (and possibly solutions) you find upstream as well as here so they (and we) are aware of the problem. You can report bugs ​here.

However, note that they have just today declared code 'Chill' today, the first step preparing for a new stable release to be numbered 0.91 which will not include GTK3 support. Focus is on cleanup, fixing of regressions, etc, in the GTK2 code.

Using +x11 the most notable problem I have seen is a lot of flashing when redrawing the display particularly during resizing and scrolling of windows that contain images larger than the window.

[Veence (Vincent)]

Thanks for the info. In my opinion, the GTK3 interface looks smarter and somehow closer to what we are used on native Cocoa UI.

FYI, I also get the same behavior when scrolling windows. Lot of flickering. Go figure, thanks for the link to report bug.

Thanks again and happy 2014!
