Error building qt4-mac

[crispy1975@…]

Hi,

I'm new to MacPorts but so far all has worked well and I've replaced Debian Linux with Leopard (PPC), however I am trying to install qt4-mac with the ultimate aim of installing kdenlive. I cannot yet get qt4-mac to compile as it fails with the same error each time. Doing a dry run suggests that everything is present and correct on the system to go ahead with the build.

I've attached a snippet from the end of the build log with debugging output, and the only other things worth mentioning are that I have the following in variants.conf:

-ipv6 -universal

Also adjusted the build target in macports.conf to be ppc64 and the universal target to "ppc ppc64".

Thanks.

What version of Mac OS X and Xcode are you running?

[crispy1975@…]

This is from memory as I'm not at the Mac right now and only have ssh access...

Mac OS X 10.5.8 XCode 3.1.2

Also if this is any use the output of 'uname -a' is:

Darwin Power-Mac-G5.local 9.8.0 Darwin Kernel Version 9.8.0: Wed Jul 15 16:57:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_PPC Power Macintosh

I need the whole debug log, to make a better assessment of this issue. If you have that on hand, you'll probably want to compress it before attaching to this ticket. If you don't have it, please 'clean' your current qt4-mac install and then reinstall it (yes, I know it takes a long time, and even longer I assume on 10.5 / PPC64); if/when it breaks again, please compress and upload that log file.

Full qt4-mac debug log.

No problem, the snippet I pasted was from a complete log file, it's compressed and attached to this ticket.

Hmm ... well, PluginView::nullEventTimerFired is supposed to be defined at "src/3rdparty/webkit/WebCore/plugins/mac/PluginViewMac.mm:685", and is enclosed by "#ifndef NP_NO_CARBON". This method is used solely at "src/3rdparty/webkit/WebCore/plugins/mac/PluginViewMac.mm:236", which is not enclosed by the #ifndef. This method is defined at "src/3rdparty/webkit/WebCore/plugins/PluginView.h:363", again without the #ifndef around it. So, maybe, NP_NO_CARBON is actually defined for your platform? Seems like a stretch since all of the libraries in the debug log are linked against "-framework Carbon", but programmaticly it's the only thing that makes sense. If you're a programmer type, can you add the "#ifndef NP_NO_CARBON" around those lines of code, such that all 3 places work or not depending on that switch? If you're not, let me know & I'll create a patch.

[michaelld (Michael Dickens)]

I'm wondering if this is a PPC64 issue. Have you tried compiling qt4-mac for just PPC (32)?

[crispy1975@…]

I can add the lines of code no problem, I'll do that first, then try compiling again. If that fails I'll give PPC a go over PPC64 and report back.

[crispy1975@…]

Success! Wrapping those lines of code in the if statements resulted in qt4-mac compiling and installing without error.

[jmroot (Joshua Root)]

There is no 64-bit version of most of Carbon. That includes ppc64.

Patch for qt4-mac to fix PluginView for no Carbon (at least PPC64)

[michaelld (Michael Dickens)]

Great! I just attached a patch that I think does what you did. Can you verify it before I update qt4-mac? Sorry to say, but Qt just released a patch to handle the bad certs issues a few weeks back -- so, if you keep your MacPorts install up to date, you get to rebuild for it! Wish there were a better way, e.g., to do incremental builds. Way beyond my pay grade here though ;)

[crispy1975@…]

I actually only put the #ifndef around the call at line 236, as my build has broken down at a later stage (glibc) I don't mind cleaning, removing, and then rebuilding to see if the patch will work from scratch. At one point another build couldn't find cmake until I make a symlink.

Will try the patch out and report back.

[crispy1975@…]

Ok, I uninstalled qt4-mac, cleaned it out, and then synced the MacPorts tree. Then I downloaded your patch into the correct port directory and edited the port file to add the following under the other patches...

# (6) Patch for Carbon on PPC64 10.5 patchfiles-append patch-PluginView-no-carbon.diff

Saved that, then ran 'sudo port -d install qt4-mac' and it compiled perfectly.

[michaelld (Michael Dickens)]

Fixed in r77577. Thanks for your assistance & promptness! Sorry about all the re-compiling; I know it takes a long time.

[crispy1975@…]

All good. I don't mind assisting with any PPC64 stuff, my G5 is a file server here so can spare the CPU cycles and it doesn't affect my workflow at all.
