On Linux you can install the compiler and all necessary python packages by using the script contained in the "install" folder:

cd path_to_winnet/install
chmod +x setup_linux.sh
./setup_linux.sh

Alternatively, you can follow the instruction below.

Fortran

In order to compile the code either the intel fortran compiler (ifort, since 2023 sometimes named ifx) or the gnu fortran compiler (gfortran) is needed. We recommend to install the ifort compiler as it comes already with the Math Kernel Library (MKL) that you need to run the network. An instruction how to install and download the ifort compiler can be found here. You need the Intel® oneAPI Base Toolkit and Intel® oneAPI HPC Toolkit. In most of the cases in Linux you can download the compiler by typing the following commands in the terminal:

wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
sudo apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
rm GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
sudo echo "deb https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list
sudo apt-get update
sudo apt-get install -y intel-oneapi-common-vars
sudo apt-get install -y intel-oneapi-compiler-fortran-2023.1.0
sudo apt-get install -y intel-oneapi-mkl-2023.1.0
echo 'source /opt/intel/oneapi/setvars.sh >/dev/null' >> ~/.bashrc

After this, open a new terminal to apply the changes.

Python

Even though not mandatory to run the network, the test suite and plotting routines use python. So we highly recommend to install the anaconda python package, which can be found here. It comes with several packages (e.g., Matplotlib, ...) that are also used in the python scripts of WinNet. The used python packages are given in "install/requirements.txt".

Using hdf5 files as output

It is not a mandatory requirement, but to be able to have hdf5 files as output, one has to modify the Makefile and install hdf5 support. To be more precise, the h5fc compiler is necessary (see, e.g, here). For example, in linux with the "apt" package manager the following command in the terminal will make the h5fc command available:

sudo apt-get install libhdf5-serial-dev

By changing the compiler with 'FC = h5fc' or 'FC = path/to/h5fc' in the Makefile, all hdf5 related parameters should work. There can be interferance with the h5fc instance that anaconda uses. This is visible when you type "which h5fc" into the terminal and it returns an anaconda path. In this case, you have to specify the full path in the Makefile. An example line in the Makefile could be, e.g.,

....
FC = /usr/bin/h5fc
....

The correct path can be displayed by the terminal command "whereis -b -f h5fc". Possibly, there are further modifications of the compiler flags necessary.
