Build failure: 4.8.5 on Mac with phonon

SGaist

It's a known bug and it's being worked on "here":https://bugreports.qt-project.org/browse/QTBUG-32832

In short, so you can get going:

Reverse your header modifications

edit src/plugins/phonon/qt7/qt7.pro

Change the line containing the Xarch to -framework QuickTime

It will build
WARNING: this is only a workaround

Thanks!

OK - your recommended modification allows the 32-bit build to get past the 32-bit build-specific error I was seeing earlier:

clang: error: invalid Xarch argument: ‘-Xarch_i386 -framework’, options requiring arguments are unsupported
clang: error: invalid Xarch argument: ‘-Xarch_i386 QuickTime’, cannot change driver behavior inside Xarch argument

This allows the build to proceed to the phonon link step, where it fails in exactly the same fashion as the 64-bit build (problem with exporting symbols for templated class). Fortunately my previously posted "fix" gets around this problem. I'll investigate a bit more, but it still puzzles me why you can get a clean build without experiencing this same link error...hmm...

Really strange… What does g++ --version print ?

bovilexic

Heh...I was going to ask you the same thing...

which g++
/usr/bin/g++

g++ --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix

I'm wondering if this is related to which version of the Command Line Tools is installed. The /usr/bin/g++ appears to the be same version as found in /Applications/Xcode.app/Contents/Developer/usr/bin/g++ (gives the exact same version info). But there still could be issues with what's in /usr/include, /usr/bin, etc...

SGaist

Same result as you…

I have the command line tools 5.0.2 5A3005

Hi, I encounter the same problem when building Qt 4.8.6 (latest version from qt.gitgourious) on my Mountain Lion
My configure is: "/configure -release -framework -arch x86_64"
My Clang version is:
"Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix"
Please let me know if there is any way to fix this problem. Thank you

bovilexic

There are several options:

When you configure the build, leave out anything phonon-related
Look at the first page of this thread, at my second post on December 6 -- you can see an edit that worked for me.
SGaist's post at the top of this page seems to have worked for him (but it did not work for me).

Thank you bovilexic.

Just an update, for the latest qt version in git, the static build has no problems in OSX 10.8.

I haven't tried the shared build.

bovilexic

Interesting...the latest 4.8.6 on git does not build properly for either 32 or 64 bits, under OS X 10.9.2 and Xcode 5.0.2. A recent purported fix for the compilation error in phonon (see my first post) can be found at:

https://codereview.qt-project.org/#change,44153

While this does remove the flaw I reported earlier, the Makefile created from the .pro file for phonon does not contain "-framework Quicktime", and so results in numerous link errors. Adding the missing item to the Makefile.Release does result in a successful link of phonon. The failed fix is supposed to be for Qt 5.x, so I expect that it will also not compile properly for 32 bit builds.

The other build failure I reported in my post of December 6 is still present, but applying the "fix" I described results (again) in a successful compilation.

Am I going to have to get involved in the bug-fixing/testing process, in order for working fixes to be applied?...this is getting rather frustrating...

Update: I can build the lastest Qt4/phonon successfully with option shared and lib_bundle, that help building Qt as frameworks.
