[vtkusers] How to build Qt-4.5.x and vtk-5.3.x for Mac OS X 10.5.5 with 64-bit Cocoa support

[Elvis Dowson]

Hi,
          I just downloaded the latest version of Qt-4.5.x and managed  
to get it to compile under Mac OS X 10.5.5 with 64-bit Cocoa support.

You will need Clinton's patch, to make QVTKWidget compile correctly  
for 64-bit Cocoa support.



Best regards,

Elvis Dowson


Technote: How to build Qt-4.5.x and vtk-5.3.x for Mac OS X 10.5.5 with  
64-bit Cocoa support

Procedure

Step 01: Download the latest version of Qt-4.5.x via rsync

The following command will list all the rsync modules available from  
the TrollTech server

rsync rsync://rsync.trolltech.com/

For example, to get Qt for all platform snapshots with rsync, choose a  
directory in which to install the distribution (your-qt-repository),  
and run the command:

rsync -avz rsync://rsync.trolltech.com/qt-all-4.5 <your-qt-repository>

Step 02: Patch vtk sources

Patch the QVTKWidget plugin sources by running the following command  
from the VTK/GUISupport/Qt/ folder

patch < qvtkcocoasupport.patch

Step 03: Configure and build Qt-4.5.x

In order to configure Qt-4.5.x for Mac OS X 10.5.5 type the following  
command

./configure -platform macx-g++ -opengl -cocoa -arch x86_64 -qt-gif - 
prefix /Developer/Applications/Qt-4.5.0

Type the following command to build Qt-4.5.x

make -j 2

Step 04: Update environment variables

Update your ~/.profile file with the following environment variables

# environment variables for vtk-5.x
export VTK_DIR=/Users/elvis/Tool/vtk-5.x/install/cocoa-shared/lib/ 
vtk-5.3
export VTK_LIB_DIR=/Users/elvis/Tool/vtk-5.x/install/cocoa-shared/lib/ 
vtk-5.3
export VTK_DATA_ROOT=/Users/elvis/Tool/vtk-5.x/data/

# environment variables for qt-4.4.3
export QTROOT=/Developer/Applications/Qt-4.5.0
export QT_PLUGIN_PATH=/Developer/Applications/Qt-4.5.0/plugins/designer

# the path is initially set to "/usr/bin:/bin:/usr/sbin:/sbin:/usr/ 
local/bin:/usr/X11/bin"
export PATH=$PATH:$QTROOT/bin

# environment variables for Tcl Tk
export TCL_LIBRARY=/usr/local/lib/libtcl8.5.dylib
export TK_LIBRARY=/usr/local/lib/libtk8.5.dylib
export TCLLIBPATH="$TCLLIBPATH \"/Users/elvis/Tool/vtk-5.x/install/ 
cocoa-shared/lib/vtk-5.3\" \"/Users/elvis/Tool/vtk-5.x/install/cocoa- 
shared/lib/vtk-5.3/Tcl\""

# the path is initially set to "/usr/bin:/bin:/usr/sbin:/sbin:/usr/ 
local/bin:/usr/X11/bin"
export PATH=$PATH:$QTROOT/bin
export DYLD_LIBRARY_PATH=$VTK_LIB_DIR:$VTKDESIGNER_LIB_DIR: 
$GCF_LIB_DIR:$GRASS_LIB_DIR:$DYLD_LIBRARY_PATH

Step 05: Install qt-4

Once everything is built, type the following command to install Qt-4.5.0

sudo make install

Qt will be installed into /Developer/Applications/Qt-4.5.0

Step 06: Configure and build vtk

Use the following settings for CMake

BUILD_SHARED_LIBS=ON

VTK_USE_CARBON=OFF
VTK_USE_COCOA=ON

CMAKE_INSTALL_PREFIX=/Users/elvis/Tool/vtk-5.x/install/cocoa-shared
CMAKE_OSX_ARCHITECTURES=x86_64

VTK_USE_64BIT_IDS=ON

VTK_USE_GUISUPPORT=ON
VTK_USE_QVTK=ON
DESIRED_QT_VERSION=4

Step 07: Check if the vtk libraries have been correctly built for x86  
64-bit architecture

cd bin
file libvtkCommon.dylib
libvtkCommon.dylib: Mach-O 64-bit dynamically linked shared library  
x86_64
