Building Slicer with Qt

• Download and install Qt. As of fall 2009, get the 4.6 technology preview version.
  • Windows - need to get source code and build with configure.exe -platform msvc2008 run vcvars32.bat first and then nmake.
    • building with webkit support requires that src/3rdparty/webkit/WebCore/tmp/moc/{debug,release}_shared/mocinclude.tmp be removed. else you will get linker errors like QNetworkReplyHandler.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall WebCore::FormDataIODevice::metaObject(void)const (?metaObject@FormDataIODevice@WebCore@@UBEPBUQMetaObject@@XZ)
  • Linux/Mac - install full QtCreator package (snowleopard not yet supported in 4.5.2)

cd Slicer3-lib
mkdir Qt
mkdir Qt-build
cd Qt
wget http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.0-beta1.tar.gz
tar xvfz qt-everywhere-opensource-src-4.6.0-beta1.tar.gz
cd qt-everywhere-opensource-src-4.6.0-beta1
echo yes | ./configure -prefix ../../Qt-build -debug-and-release -opensource  -no-qt3support 
make -j 16
make install
