Download OpenFOAM 1.6-ext from the Internet
You can use svn to get the whole extended source code:
$svn co https://openfoam-extend.svn.sourceforge.net/svnroot/openfoam-extend openfoam-extend
If you only want to download the 1.6-ext version, execute:
$svn co https://openfoam-extend.svn.sourceforge.net/svnroot/openfoam-extend/trunk/Core/OpenFOAM-1.6-ext/ OpenFOAM-1.6-ext
After first retrieving, you may need update the source code:
$cd openfoam-extend
$svn update
source the etc/bashrc file by adding the following line to the end of your $HOME/.bashrc file:
+ . $HOME/OpenFOAM/OpenFOAM-1.6-ext/etc/bashrc
Then update the environment variables by sourcing the $HOME/.bashrc file by
typing in the terminal:
$. $HOME/.bashrc
Build the ThirdParty packages:
$cd /ThirdParty
$./AllMake.stage0
$./AllMake.stage1
$./AllMake.stage2
$./AllMake.stage3
$./AllMake.stage4
Except the stage4, you need to download the source tarball manually if any failure of downloading source files.
Then compile OpenFOAM 1.6-ext the core and applications. You should go to the top directory of your OpenFOAM-1.6-ext folder:
$cd openfoam-extend/trunk/Core/OpenFOAM-1.6-ext/
or any other location for your OpenFOAM-1.6-ext, then
$./Allwmake
A new error appears when compiling the /OpenFOAM-1.6-ext/applications/:
~/OpenFOAM/OpenFOAM-1.6-ext/lib/linux64GccDPOpt/openmpi-1.4.3/libPstream.so so try adding it to the linker command line
~/OpenFOAM/OpenFOAM-1.6-ext/lib/linux64GccDPOpt/openmpi-1.4.3/libPstream.so: could not read symbols: Invalid operation
To fix this: In file $WM_DIR/rules/linux64Gcc/c++ change the lines for LINKLIBSO and LINKEXE to:
LINKLIBSO = $(CC) $(c++FLAGS) -shared -Xlinker --add-needed
LINKEXE = $(CC) $(c++FLAGS) -Xlinker --add-needed
Then, you execute it again in the top directory of OpenFOAM-1.6-ext
$./Allwmake
I think you can use OpenFOAM-1.6-ext now.
