Qt 4.8.2 libraries and Mountain Lion

hocheung20

When trying to compile the libraries under Mountain Lion, I get:

g++ -headerpad_max_install_names -arch x86_64 -single_module -dynamiclib -compatibility_version 4.9 -current_version 4.9.2 -install_name /usr/local/Trolltech/Qt-4.8.2/lib/QtWebKit.framework/Versions/4/QtWebKit_debug -Xarch_x86_64 -mmacosx-version-min=10.5 -Xarch_x86_64 -mmacosx-version-min=10.5 -o QtWebKit_debug .obj/debug-shared/WebSystemInterface.o .obj/debug-shared/QTKitFullScreenVideoHandler.o .obj/debug-shared/MathMLNames.o .obj/debug-shared/MathMLElementFactory.o

Is anyone else experiencing the same issue?

I'm experiencing this problem, too. Trying to build qt4-mac with MacPorts 2.1.2.
It might be linked to this: https://trac.macports.org/ticket/35313

There is a patch in review to fix this issue: https://codereview.qt-project.org/#change,31646

It's happening to me as well, I just got my mac and using this build configuration:
@
./configure -debug-and-release -opensource -largefile -plugin-sql-sqlite -no-qt3support -xmlpatterns -multimedia -audio-backend -svg -webkit -javascript-jit -script -scripttools -declarative -declarative-debug -qt-zlib -qt-libtiff -qt-libpng -qt-libmng -qt-libjpeg -openssl -I /usr/include -L /usr/lib
@

How do I apply the patch on "change 31646":https://codereview.qt-project.org/#change,31646 ?

I'm also using mountain lion, and I'm a bit new to the mac, so if someone can help me step by step, I would be really grateful

EDIT:
Also found another patch that is related to the issue in the macports link specified above, it's "change 31759":https://codereview.qt-project.org/#change,31759 which is related to QtWebKit

You could also change the build environment to Qt 4.8.0, I personally find it more stable, and it gives me less errors and warnings.

raulgd

Yes but I would like to use 4.8.2 as it has many bug fixes and stuff on QML which I'm using, so it would be nice if someone could help me apply the patches

Ok I figured out how to apply the patch 31646, also patch 31759 is about the same as 31646.

There was just a small difference in the QtWebKit.pro file and needed to add the mountain lion interface library to the webkit project.

When applying the patch, I'd recommend to download the file libWebKitSystemInterfaceMountainLion.a from the github repository mentioned in the patch comments at the beginning of the page instead of the one in the patch page, because there's an 8kb difference when downloading from the patch page than straight from github, I don't know what are the differences but I wouldn't want to find out after 2 hours of building Qt that it was just zip file rubbish ;)
