[SOLVED] Building Qt 5.3 Alpha on Mac: webkitwidgets and webkit built successfully, but are unavailable

Violet Giraffe

Just to reiterate: I've built QtWebkit successfully - without ICU and Ruby. In fact, I've configured Qt with -no-icu, and I still got QtWebkit framework built. Are you saying it's non-functional and that's why it is not detected by qmake? I think building QtWebkit took more than half the total time to build Qt.

How do you get that error message?
Do you run examples or trying to build something using the modules?

Take a look on the installation directory Qt_install_root/lib and verify that you have QtWebkit framework installed and it contains something.

Violet Giraffe

QtWebKit.framework is far from empty, 183.4 MB. It is located at the correct path.
I get this error when running qmake on a .pro file that has QT += webkit

Mac OS X requires some additional steps to be done if you build it by yourself.

What does otool -L shows?
@
otool -L /Qt_install_root/lib/QtWebKit.framework/QtWebKit
@

if it does not show correct path to QtWebKit then you need to modify it using install_name_tool
@
install_name_tool -change QtWidgets.framework/Versions/5/QtWidgets /Qt_install_root/lib/QtWidgets.framework/Versions/5/QtWidgets /Qt_install_root/lib/QtWidgets.framework/Versions/5/QtWidgets
@

The same steps need to be done for all shared libraries.

"Qt for Mac OS X - Deployment":http://qt-project.org/doc/qt-5/macosx-deployment.html gives more details on it.

Thanks for the advice, but I don't see anything wrong here:

I want to stress that my application uses core, gui, network, script, opengl, widgets and webkit components, of which webkit is the only problematic one. If I remove webkit dependency from the application, I can build and run it no problem.

Is it possible that you have another version of Qt without webkit and you run qmake from that Qt?

Violet Giraffe

No, I don't believe so. i've got 3 versions of Qt, of which all have webkit. Plus, I'm running qmake from Qt Creator where I have 3 kits configured, so I'm pretty sure I've got the right qmake.

andreyc

Try to run qmake manually with -d option
@
qmake -d -recursive your_sources_dir
@

It will produce a lot of info

andreyc

And just to be sure run qmake -v to verify that you are calling qmake from correct Qt.

Violet Giraffe

If I run qmake manually from an arbitrary dir, I will get qmake for 4.8.5 which, apparently, I have in PATH and I need to preserve this behaviour. In Qt creator, I have all my 3 Qt versions configured, and I have manually pointed each to the right qmake.

Violet Giraffe

Aha! It was a problem with qmake. It was the right qmake, but I was using a copy located elsewhere. Once I pointed to the same qmake in /usr/local/Qt-5.3.../bin, it all started working. Thanks!
