Qt 4.8 beta and Mac OSX Lion, Phonon error

After a successful install of mac OS 10.7 I tried to compile my qt 4.7 project.

I had many warnings of "unsupported mac os x version". I thus decided to use Qt 4.8 beta and now, all the warnings are gone.

However, I now have a linker problem using Phonon:

dyld: Library not loaded:/Users/pulseagent/repos/build2/Desktop/Qt/4.8.0/gcc/lib/QtDBus.framework/Versions/4/QtDBus
Referenced from: /Users/kikohs/QtSDK/Desktop/Qt/4.8.0/gcc/lib/phonon.framework/Versions/Current/phonon
开发者_如何学编程Reason: Incompatible library version: phonon requires version 4.8.0 or later, but QtDBus provides version 4.7.0

Do you know I could I fix this ?

Thanks!

You could easily install QT under Lion using homebrew(which already has a fix for this):

1. install homebrew using

   /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

2. install qt using

   brew install qt --build-from-source

For now I decided to stick with Qt 4.7.3, to remove the warnings I hacked the qtglobal.h and added Mac 10.7 as a supported version.

It seems to run fine ...

I would recommend using MacPorts. If you download the MacPorts installer 2.0.0 (latest at the time of writing) you can unpack the qt4-mac-devel-4.8.0-beta1.tgz file posted at the end of this MacPorts trac report over the qt4-mac-devel port, in order to get 4.8.0 beta 1 working under Lion.

It's not official yet, but then nor is Qt 4.8.0. It seems to work well and can be used to build Qt Creator 2.2.1 without problems.

I'm using Qt Creator 2.2.1 and Qt 4.7.4 (64 bit).

While a build in Lion reported a number of warnings (to do with the Mac OS version) the resulting app did work as expected.

Using the macdeployqt tool ( QtSDK/Desktop/Qt/473/gcc/bin/macdeployqt ), with the -dmg switch, creates a dmg file from the app with all of the required dependencies.

And while this reported a number of errors (to do with copying nib files) the resulting dmg file still worked as expected.
