Install dependencies

sudo apt install libcairo2-dev
sudo apt install libgsl-dev
sudo apt install libgtk-3-dev

Download the code

git clone git://ibsimu.git.sourceforge.net/gitroot/ibsimu/ibsimu

cd ibsimu
./reconf

You may need to adjust the prefix path in the ./configure line to the folder where you downloaded the repository.

Enviroment variables

Before you compile any project you have to set some environment variables:

export PKG_CONFIG_PATH=`pwd`
export LD_LIBRARY_PATH=`pwd`

If you want that to run any time you open a new console/terminal you can place those commands in your .bashrc. First find the current path:

cd
nano ~/.bashrc

copy both lines at the end and save:

export PKG_CONFIG_PATH="/PATH/TO/IBSIMU/FOLDER"
export LD_LIBRARY_PATH="/PATH/TO/IBSIMU/FOLDER"
