qt4-mac: trouble with libqcorewlanbearer.dylib (OS X 10.7)

following error occurs while compiling qt4

Use WikiFormatting please. Remember to fill in the correct port name (qt4-mac not qt4), Cc that port's maintainer, and also please attach the entire main.log.

[m.haller@…]

After the error occured, I checked the log file and tried again

cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_qt4-mac/qt4-mac/work/qt-everywhere-opensource-src-4.7.3"
make all

... but without -j3 ... then I got the error messages above

this works together with the above patch of patch-src-plugins-bearer-corewlan-corewlan.pro.diff

compilation and linking of libqcorewlanbearer.dylib is error free

dear macports team, please test and submit these fixes

[m.haller@…]

Please check also Ticket ​29141 ... /qt4-mac/work/qt-everywhere-opensource-src-4.7.3/src/corelib/global/qglobal.h has to be patched as well

[michaelld (Michael Dickens)]

There's probably a way to make the corewlan.pro patch more generic, by moving it into the Portfile as a 'reinplace'. I don't know about the other change, since I don't have 10.7 yet.

I'm traveling right now, and probably won't be able to download / install Lion until early August. So, unless someone can come up with a patch in the interim, folks will just have to be patient for a few weeks until I can get to this ticket. I grant permission for others to checkin fixes for this ticket, if/as appropriate.

[m.haller@…]

I confirm that the above fixes are enough to obtain a working port of qt-everywhere-opensource-src-4.7.3 ... successful installation is possible

Replying to m.haller@…:

Wouldn't your patch make building fail on 10.6 for all those who do not yet intend to upgrade their MacOSX to Lion?!

[nerdling (Jeremy Lavergne)]

Like the patches need to become conditional based on what SDK is available.

[m.haller@…]

Replying to mk@…: Replying to snc@…:

Sure, the patch should depend on the version of OS X and the version of Qt SDK. Probably, this issue will be resolved in a future version of Qt. I'm hopeful that Michael will consider this.

I have a question:

I modified the files corewlan.pro and qcorewlanengine.mm but yet after a (sudo) make clean and make all in src/plugins/bearer i still get the same error message.

The modification of corewlan.pro is straight forward, but in qcorewlanengine.mm i just added the lines proposed in the beginning of the file. Did i do it wrong? should i remove some includes???

The changes of qglobal.h did work and i could compile src/corelib/

Thx

[wanthalf@…]

Replying to fares.chucri@…:

Neither for me. I had to remove the conditions completely from the corewlan.pro file and *then* it finally compiled. I.e., I only left there the lines:

LIBS += -framework CoreWLAN -framework Security
DEFINES += MAC_SDK_10_7

(Obviously, this is no solution, just a workaround for my system.)

[m.haller@…]

Replying to wanthalf@…:

Was QMAKE_MAC_SDK set to MacOSX10.7.sdk? maybe there is some problem with the conditions ...

Where is QMAKE_MAC_SDK set? Removing the condition allowed me to compile src/plugins/bearer

qt4-mac is still compiling but it looks ok until now.

Same problem here with the same solution. Thanks

qt4-mac built successfully finally based on your suggestions above, thanks.

unfortunately redland is the next broken one (while installing kde4-baseapps)

:info:build make[3]: *** No rule to make target `-lltdl', needed by `librdf.la'.  Stop.

Multiple solutions have been suggested above. Please attach a patch in unified diff format.

Hi, the changes don't work for me: After 30 minutes of frantic compiling the issue of undefined symbols comes back:

:info:build Undefined symbols for architecture x86_64: :info:build "_kCWPowerDidChangeNotification", referenced from: :info:build -[QNSListener init] in qcorewlanengine.o

frustrating...I hope there will be a patch soon.

Anyway, thanks Michael and M.!

I have attached Portfile and additional patches. With that I have managed to compile the qt4-mac.. hope it helps to create official solution :) Thanx for sharing your fixes

[raimue (Rainer Müller)]

This patch patch-src-plugins-bearer-corewlan-corewlan.pro.diff would probably produce build errors on Snow Leopard and earlier releases. It either needs to be reworked to support multiple OS X versions or there have to be multiple patches applied conditionally.

[michaelld (Michael Dickens)]

The patch for "patch-src-plugins-bearer-corewlan-corewlan.pro.diff" doesn't work on 10.6. We need a 2-step approach, to replace both the DEVELOPER_DIR and OS version. I'm working on it & will post updates Friday morning.

[raimue (Rainer Müller)]

At least I can confirm that after hours and hours, qt4-mac built for me on Lion with these patches. Thanks a lot!

[michaelld (Michael Dickens)]

OK; this afternoon. It's taking longer than expected to re-do the Portfile to make it all work cleanly.

[michaelld (Michael Dickens)]

Committed in r81844. Please do a selfupdate & see if the changes work.

[trottier@…]

Thanks!!

Original problem seems to be gone after doing a selfupdate and "port clean qt4-mac" (*still* building). Lots of "This version of Mac OS X is unsupported" warnings, though.

[trottier@…]

Correction: the error is still there (??)

Will clean, selfupdate, and try again ...

Worked!

[michaelld (Michael Dickens)]

Great! It works for me on 10.6, XCode 3 (latest). I'm hopeful it'll also work using 10.6, XCode 4 (waiting to hear back, snc :). I'll also double-check on 10.7 once I get that installed later this weekend.

[michaelld (Michael Dickens)]

It also worked for me on 10.7!
