Tried to compile things under snow leopard.
I get the following error:

...rary/Frameworks/QtCore.framework/Headers/qglobal.h:283:2: error: #error "You are building a 64-bit application, but using a 32-bit version of Qt. Check your build configuration."

The arch flag is set i386 in CMAKE.

Somone knows whats wrong?

cheers

Sorry, neither of us have Mac OS X to support it. Here is some information on how to do it but I haven't checked it myself http://www.dsource.org/projects/qtd/ticket/37 . Sorry for the late reply.

Hello. Firstly, it's not hard to get the ball rolling on a snow leopard compilation. Just follow the existing Mac instructions about building qt:

http://www.dsource.org/projects/qtd/wiki/BuildMacOSX

Note that the dmd compiler patch is very simple and still works on v2.048 sources.

Now when you get to the step for compiling qtd, use the following modified cmake command from the build_dir to build 32bit:

cmake -DCMAKE_CXX_FLAGS:STRING=-m32 ../

Though things run for awhile, I eventually ran into a handful of problems in my attempt to get the full qtd compile working.

1) Two constructors in QGraphicsTextItem_shell.cpp seem to be invalid. The chained constructor line:

QtD_QObjectEntity(this, dptr)

Is no good both because the symbol dptr is doubly inherited and neither version can be cast to a void*. I replaced both with:

QtD_QObjectEntity(this, NULL)

crossed my fingers and kept going.

2) The file QPixmapCache_shell.cpp seems to have two identical methods:

extern "C" DLL_PUBLIC bool qtd_QPixmapCache_insert_string_QPixmap
(DArray key0,
void* pixmap1)

so comment one of the two out.

3) Many qt/d2/qt/core/*.d files have non-const opEquals methods. For any compiler errors, change signatures looking like:

bool opEquals(ref QRect r)

to

bool opEquals(ref const QRect r) const

These three patches got me through the generateor, dgen, and cpp_{core/gui/network/opengl/xml/svg/webkit}. But then I finally bomb out with errors in Signal.d that stumps me good:

/Users/tom/installs/qtd/trunk/qt/d2/qt/Signal.d(713): Error: Cannot interpret *cons at compile time

make[5]: *** [CMakeFiles/qtdcore.dir/qtdcore0.o] Error 1

I think line 1121 of Signal.d:

mixin (SignalEmitter!(A)(signalType, name, index));

Is causing a compile time error in emit:

void emit(A...)(size_t signalId, A args)
[...]
auto cons = &connections[signalId];
[...]
// line 713 below
static const c = cons.slotListCount;

My guess is that my qt and/or dmd is too new. I'm running:

If anyone can give me some pointers or let me know if I've wondered off onto the wrong track, it would be appreciated.
