Sundials

PyFMI needs least Sundials 2.5/2.6, only 2.4.0 install works due to different build method (CMake over Make)

mkdir ~/pyfmi
cd ~/pyfmi
wget -qO- https://computation.llnl.gov/projects/sundials/download/sundials-2.4.0.tar.gz | tar xvz
cd sundials-2.4.0
# only set the below CFLAGS if running x64 system
sudo ./configure CFLAGS="-fPIC"
make
sudo make install

FMILibrary

Needs at least 2.0.1

cd ~/pyfmi
svn checkout https://svn.jmodelica.org/FMILibrary/tags/2.0.3b1/ FMILibrary-2.0.3b1
mkdir build
cd build
sudo cmake -Wno-dev -DFMILIB_INSTALL_PREFIX=/home/luke/pyfmi/FMILibrary-2.0.3b1 ../
sudo make install test

# add fmilib.h to C compile path
nano ~/.profile
# add:
export C_INCLUDE_PATH=/home/luke/pyfmi/FMILibrary-2.0.3b1/install/include
# (^X to close, Y to save)

# reload .profile
source ~/.profile

# optional, check if it has loaded properly
echo $C_INCLUDE_PATH

LAPACK

Only need if using a GLIMDA solver

wget -qO- http://www.netlib.org/lapack/lapack-3.8.0.tar.gz | tar xvz
mv make.inc.example make
make

Assimulo

cd ~/pyfmi
wget https://files.pythonhosted.org/packages/4c/c0/19a54949817204313efff9f83f1e4a247edebed0a1cc5a317a95d3f374ae/Assimulo-2.9.zip

unzip Assimulo-2.9.zip
rm Assimulo-2.9.zip

sudo python setup.py install --sundials-home=/home/luke/pyfmi/sundials-2.6.0 --blas-home=/usr --lapack-home=/usr

PyFMI

cd ~/pyfmi
svn checkout https://svn.jmodelica.org/PyFMI/tags/PyFMI-2.3.1/ PyFMI-2.3.1
cd PyFMI-2.3.1

Modelica

for deb in deb deb-src; do echo "$deb http://build.openmodelica.org/apt `lsb_release -cs` release"; done | sudo tee /etc/apt/sources.list.d/openmodelica.list

wget -q http://build.openmodelica.org/apt/openmodelica.asc -O- | sudo apt-key add - 

apt-key fingerprint

sudo apt update
sudo apt install openmodelica

# Havent yet done (has a broken dependency, so seeing if needed):
sudo apt install omlib-.* # Installs optional Modelica libraries (most have not been tested with OpenModelica)
