[Qt-interest] newbie having trouble compiling wiggly demo on Mac

[Eric Smith]

I'm using qt-sdk-mac-opensource-2009.02.dmg on Mac OS 10.5.6. gcc 
--version reports i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. 
build 5484).

Since I don't want to use Xcode, I copied all of the .h and .cpp files 
of the wiggly demo directory into a new directory, then did:

qmake -project
qmake -spec macx-g++
make

The two invocations of qmake didn't give any complaints, but make does:

$ make
g++ -c -pipe -g -gdwarf-2 -Wall -W -DQT_GUI_LIB -DQT_CORE_LIB 
-DQT_SHARED -I/usr/local/Qt4.5/mkspecs/macx-g++ -I. 
-I/Library/Frameworks/QtCore.framework/Versions/4/Headers 
-I/usr/include/QtCore 
-I/Library/Frameworks/QtGui.framework/Versions/4/Headers 
-I/usr/include/QtGui -I/usr/include -I. -I. -I. -I. 
-F/Library/Frameworks -o dialog.o dialog.cpp
dialog.cpp: In constructor ‘Dialog::Dialog(QWidget*)’:
dialog.cpp:51: error: ‘WigglyWidget’ was not declared in this scope
dialog.cpp:51: error: ‘wigglyWidget’ was not declared in this scope

dialog.cpp:55: error: no matching function for call to

QObject::connect(const QObject*, const char*, const char*, 
Qt::ConnectionType) const
make: *** [dialog.o] Error 1
$

What am I doing wrong? Do I need something more elaborate in my use of 
qmake in order to get the right dependencies into the Makefile or something?

Thanks!
