# About QT4
#
# Ubuntu 12.04 comes with QT4 version 4.8.1
# Even thoug ParaView will compile with this version of QT, ParaView will also generate a bunch of
# warnings on the console at runtime. So we will be using the version of QT4 supplied with the
# ThirdParty packages.

#Uncomment the variable QT_THIRD_PARTY in the file prefs.sh

sed -i s/"#export QT_THIRD_PARTY=1"/"export QT_THIRD_PARTY=1"/g ~/OpenFOAM/OpenFOAM-1.6-ext/etc/prefs.sh

# This section of the prefs.sh file should now look like this:

export QT_THIRD_PARTY=1
#export QT_DIR=/usr
#export QT_BIN_DIR=$QT_DIR/bin

--------------------------------------------------------------------------------

# Source your OpenFOAM environment to get the basic configuration for
# compilation
. ~/OpenFOAM/OpenFOAM-1.6-ext/etc/bashrc

--------------------------------------------------------------------------------

# Compile the ThirdParty packages
cd $WM_PROJECT_DIR/ThirdParty
./AllMake.stage1 >& log.AllMake.stage1
#./AllMake.stage2 >& log.AllMake.stage2   # No need for this one
./AllMake.stage3 >& log.AllMake.stage3
./AllMake.stage4 >& log.AllMake.stage4

--------------------------------------------------------------------------------

# Update your OpenFOAM environment to get the basic configuration from the newly
# compiled ThirdParty packages
. ~/OpenFOAM/OpenFOAM-1.6-ext/etc/bashrc

# Compile OpenFOAM-1.6-ext
cd $WM_PROJECT_DIR
./Allwmake >& log.Allwmake &
tail -f log.Allwmake          # To keep an eye on the compilation process

--------------------------------------------------------------------------------

# Run a tutorial to check the basic functionality
cd $FOAM_TUTORIAL/incompressible/simpleFoam/pitzDaily

# You are done!
