# Download OpenFOAM-1.6-ext

# We are going to use version 4.6.4 of gcc, provided by the ThirdParty packages
#
# The version of gcc 4.8.1 provided by Manjaro is too recent for the git 'master' branch.

# We are going to use the version of QT4 provided by Manjaro
# Unfortunately, the 'qmake'  command on Manjaro is called 'qmake-qt4'
# The compilation script for ParaView requires a command called 'qmake'.
# So we are going to make a symbolic link in order to create a 'qmake' command,
# but this should be seen as a bad fix. A much better fix will be contributed under
# 'nextRelease' branch. Until then, this will have to do.

# Uncomment and modify the initialization of the variables QT_DIR in the

# Source this initial OpenFOAM environment to get the basic configuration for

# You will get some warnings about missing file for gcc-4.6.4, and problem with

# This is quite normal, your gcc-4.6.4 compiler is not even compiled and
# installed yet. Patience patience...

# Compile the ThirdParty packages, including the gcc 4.6.4 compiler

# You can also generate the Doxygen documentation, which is quite handy if
# you plan to poke around the OpenFOAM source code

cd $WM_PROJECT_DIR/doc
./Allwmake


# You are done!
