In order to run the simulator:
clone the simulator repo:
git clone https://gitlab.eurecom.fr/ris-esi/ris-simulator.git
cd ris-simultor
# download dependencies
go mod tidy
# build the binary
go build .
# run the test
TO BE ADDEDclone the flexric repo and download the dependecies it requires:
few compilation dependencies which are not mentioned in the ReadMe so execute the following:
Note: the following commands may break some other dependencies in your system, so better run this in a VM
sudo apt -y install gcc-9 g++-9 gcc-10 g++-10
sudo apt update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 9
sudo apt update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-9 9
sudo apt update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10
sudo apt update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10
# to make sure that the commands ran successfully
sudo update-alternatives --config gcc
sudo update-alternatives --config gccafter that follow the build instructions in flexric repo.
To run the simulation we can use the default configuration in the "init.json" or we can make our own by making changes to the file (don't forget to backup the default config)
Note: for this version of the simulator we can support up to 64 RIS elements (until we can fix the what seems to be a buffer overflow in the flexric)

Now that everything is set-up we can run our simulation:
