Building Slicer with Qt

• Download and install Qt. As of winter 2009, get the 4.6 version.
  • Windows - need to get source code. On the LGPL tab, select the source code download page for windows and visual studio 2008, and note that there is a link below where you can download the source code in a zip archive.
    • 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)
    • Note: Using the Qt Designer on Windows requires that the Slicer widget plugins are compiled in the same mode than Qt. If Qt is compiled in Release mode (default), Slicer must be compiled in Release. If Qt is compiled in Debug mode only, Slicer must be compiled in Debug. (however if Qt is in Release and Debug, Slicer must be in Release).
  • Linux/Mac - install full QtCreator package (use "-arch x86_64" for a 64 bit build on snowleopard)

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.tar.gz
tar xvfz qt-everywhere-opensource-src-4.6.0.tar.gz
cd qt-everywhere-opensource-src-4.6.0
echo yes | ./configure -prefix ../../Qt-build -debug-and-release -opensource  -no-qt3support 
make -j 16
make install
