1 Introduction

This page is dedicated to preparing an Ubuntu system for installing the foam-extend project .

2 Ubuntu versions

2.1 Ubuntu 18.04 LTS

Run the following commands:

sudo apt-get update

sudo apt-get install git-core build-essential binutils-dev cmake flex \
zlib1g-dev  libncurses5-dev curl bison \
libxt-dev rpm mercurial graphviz python python-dev python3 python3-dev

Then follow the instructions on the previous page, subsection Get the source code. Ubuntu 18.04 LTS comes with gcc/g++ 7.4.0 as default, so does not need any other adaptation of the standard process.

OPTIONAL: Preparations if you want to compile the version of Paraview that comes with foam-extend-4.1:

Paraview needs the QT4 library to compile:

sudo apt-get install qt4-dev-tools libqt4-dev

If you want to compile Paraview you also need to tell foam-extend where to find QT4:

echo "export QT_BIN_DIR=/usr/bin" >> etc/prefs.sh
echo "export WM_THIRD_PARTY_USE_QT_5111=1" >> etc/prefs.sh
echo "export WM_THIRD_PARTY_USE_PARAVIEW_552=1" >> etc/prefs.sh
 
source etc/bashrc

Now you can start the compilation by issuing:

./Allwmake.firstInstall

2.2 Ubuntu 20.04 LTS

Run the following commands:

sudo apt-get update

sudo apt-get install git-core build-essential binutils-dev cmake flex \
zlib1g-dev qt4-dev-tools libqt4-dev libncurses5-dev curl bison \
libxt-dev rpm mercurial graphviz python python-dev  gcc-7 g++-7

Then follow the instructions on the previous page, subsection Get the source code, but keep in mind to run a few additional commands before you run source etc/bashrc in order to set the environment for gcc/g++ 7 to be used instead of gcc/g++ 9. More specifically, the commands should be executed something like this:

cd ~/foam/foam-extend-4.1
 
echo "export WM_CC='gcc-7'"  >> etc/prefs.sh
echo "export WM_CXX='g++-7'"  >> etc/prefs.sh
 
source etc/bashrc

Then before running Allwmake.firstInstall, run the following commands:

sed -i -e 's=rpmbuild --define=rpmbuild --define "_build_id_links none" --define=' ThirdParty/tools/makeThirdPartyFunctionsForRPM
sed -i -e 's/gcc/\$(WM_CC)/' wmake/rules/linux64Gcc/c
sed -i -e 's/g++/\$(WM_CXX)/' wmake/rules/linux64Gcc/c++
