Qt-mac-free-3.3.4 on Mac OS X Tiger

Hint

If you don’t need specifically qt-mac-free-3.3.4 but any 3.3.x would do it, you might want to check out Trolltech’s recently published Version 3.3.5. If you ever wondered – like me – where you can still download the 3.3.x branch have a look at

ftp://ftp.trolltech.com/qt/source/

It seems that you can’t find any more download links for 3.3.x at Trolltech’s webpage.

Issue

When I tried to compile Qt for Mac 3.3.4 from source on Max OS X Tiger 10.4.2 with gcc-4.0.0 the compiler complained:

kernel/qaccessible_mac.cpp:189: error: non-local variable 
'<anonymous struct> text_bindings [][10]' uses anonymous 
type
make[2]: *** [.obj/release-shared/qaccessible_mac.o] Error 1
make[1]: *** [sub-src] Error 2
make: *** [init] Error 2

and

sockaddr*, int*)':

Additionally with both compilers gcc 4.0 and gcc 3.3 linking an application against qt-mac-free-3.3.4 resulted in warning messages like the following, because Mac OS X Tiger comes with additional dynamic library handling functions which now conflict with qt:

Solution

Apply the following patch:

qt-mac-free-3.3.4-tiger.diff

Patch instructions

Extract sources and apply patch:

tar xjf qt-mac-free-3.3.4.tar.bz2
cd qt-mac-free-3.3.4
patch -p1 <../qt-mac-free-3.3.4-tiger.diff

Please make sure that the paths are adjusted to your system. Follow the official build instructions afterwards. After applying the little patch qt-mac-free-3.3.4 and applications linked to it should build fine with gcc 4.0 and gcc 3.3.
