OS X 10.6 with +no_x11 +quartz: Pango-WARNING **: shaping failure, expect ugly output

[macports@…]

$ gtk-demo 

(gtk-demo:90990): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='BasicEngineFc', font='Lucida Grande Medium 12', text='Application main window'

(gtk-demo:90990): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='BasicEngineFc', font='Bitstream Vera Sans 18', text='Application main window'

The result is demo1.png. The same goes for pidgin (that I was trying to build). To rule out a mixture of -no_x11 and +no_x11 ports I created a fresh macports install with a variants.conf containing:

+universal +no_x11 +quartz

(+universal is needed because of #20284)

Note that pango-view cannot be used for testing because ImageMagick is built without X11 support in this scenario.

This may be the same as or closely related to #17049.

[macports@…]

It might be. I don't understand all the technical lingo in that bug. The version I have installed is:

$ sudo port installed pango
The following ports are currently installed:
  pango @1.24.5_0+macosx+no_x11+quartz+universal (active)

[tim.stoop@…]

I've tried the latest Pango as mentioned in #17049, but now I'm not even getting a demo screen anymore. I've rebuild gtk2 after installing the newer Pango (from the Portfile by vitaly@).

[macports@…]

This bug still occurs with the latest ports without the +universal:

$ port installed | egrep 'pango|cairo|gtk2'
  cairo @1.8.8_0+macosx+no_x11+quartz (active)
  gtk2 @2.18.2_0+no_x11+quartz (active)
  pango @1.24.5_0+macosx+no_x11+quartz (active)

Has duplicate #23028.

I don't really know what to do about this problem. I don't use pango's quartz or no_x11 variants, nor gtk2. I suggest you test whether pango 1.26.x would fix this problem. The reason pango has not been updated to this version is explained in #21624. If pango 1.26.x fixes the problem, test if the issue described in #21624 still exists; if so, encourage the developers of pango to fix it. If 1.26.x does not fix the shaping failure, report that problem to the developers of pango.

Just to clarify here: pango version 1.26.2 doesn't fix the problem, shaping failures still are present.

This Portfile worked for me:  http://trac.macports.org/attachment/ticket/17049/Portfile

$ port installed | egrep 'cairo|pango|gtk2'
  cairo @1.8.8_0+macosx+no_x11+quartz (active)
  gtk2 @2.18.6_0+no_x11+quartz (active)
  pango @1.24.5_0+macosx+no_x11+quartz
  pango @1.26.0_0+macosx+no_x11+quartz (active)
  py26-cairo @1.8.8_0 (active)

[farcaller@…]

I second this, given Portfile works ok here.

[johnrosshunt@…]

I'll third it. The Portfile works for me as well.

[ryandesign@…]

And are the three of you claiming that using that pango 1.26.0 portfile, you do not experience the slowdowns reported in #21624 (which is the reason why we have not updated to 1.26.x so far)?

[farcaller@…]

Yes, cannot reproduce that any more ant that's pretty strange. However gtk-demo and wireshark work ok and I have no signs of #21624.

[johnrosshunt@…]

I haven't noticed the problems from #21624 but I've noticed two other bugs. Menu shortcut labels (e.g. Ctrl+S, Alt+Q, etc.) are distorted and right clicks aren't working. I have no idea if this is GTK or Pango related, or both.

[tim.stoop@…]

I can confirm this works for me too, without any slowdowns. I do not however use liferea or rrdtool, I use gtimelog. Shortcuts work for me too, as does right clicking.

That portfile didn't work for me, I got

Error: Unable to open port: Error evaluating variants

[jmr@…]

Someone was saying on IRC that pango 1.28 seems to be OK.

[thmx.2k7@…]

pango-devel @1.27.1_0 works fine for me

[mike@…]

I had to modify the Portfile at  http://trac.macports.org/attachment/ticket/17049/Portfile to support the "macosx" variant. Once I did that, I was able to build pango 1.26.0 on Snow Leopard (10.6.4) and GTK2/Quartz applications displayed fonts properly. This is an important bug fix. Is there something holding up the new pango package?

[ryandesign@…]

Replying to mike@…:

Mostly just apathy. If someone will provide a patch that will update the pango port to the latest version and incorporate any relevant changes from the pango-devel port I'll probably commit it.

[ryandesign@…]

Mike, see my comment above.

Patch pango port to build 1.28.1; fixes ticket #20924

[devans@…]

I'd like to add support for this update request for the following reasons:

• pango 1.28.1 is the current version distributed with the GNOME 2.30.2 release

• current version of pango (1.24.5) does not support GObject introspection while 1.28.1 does. This is a gating item for enabling introspection in gtk2 and its dependents

To this end, in the attached patch file I have added to mike's contributions the following:

• disable introspection by default to avoid autoconfiguration if port gobject-introspection is installed

• add +introspection variant to enable introspection

This builds for me on SL x86_64 and Leopard ppc non-universal with and without the +introspection variant and builds universal in all cases except +introspection where it fails in the introspection process -- hence the variant approach. Perhaps some one else can figure out how to fix this one case.

[devans@…]

Upgrade to 2.28.1 including +introspection variant

[devans@…]

I've just confirmed that gimp2 @2.6.10_3+no_x11+quartz using pango @1.24.5_0+no_x11+quartz shows the same problem, that is, gimp2 emits the following warnings

gimp:18410): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='BasicEngineFc', font='Lucida Grande Medium 9.9990234375', text='Plug-In Interpreters'

(gimp:18410): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='BasicEngineFc', font='Lucida Grande Medium 12', text='Looking for data files'

and characters in the startup screen and other windows display as open boxes only (ugly).

Upgrading to 1.28.1 fixes the problem.

Mac OS 10.6.4 x86_64

Do not delete the epoch option from the Portfile. This setting should never be removed anymore after it has been added.

I can confirm that upgrading to 1.28.1 using the patch from devans solves this issue. Thanks! What needs to be done for this to be added to the central repository?

[devans@…]

Here's an update to the latest patch that removes some -devel-isms (e.g. my_name) and removes the +introspection variant for now since it breaks the universal build.

[devans@…]

Revised patch file

[johnrosshunt@…]

I can confirm that the  patch-pango-1.28.1-introspection-revised.diff patch works for me as well.

Patch to upgrade to latest pango 1.28.3 attached to #26697.

The problem still exists with pango 1.28.4 gtk-quartz is unusable.

[maltee@…]

Replying to maltee@…:

This was not my problem. My problem was, that pango was not automatically installed with +quartz (or not reinstalled after cairo was installed with +quartz). Please close this bug again, sorry for false alarm!
