I'm following the instructions in rocket-chip v1.6 to install and run rocket-chip. As mentioned there, I need to install rocket-tools first (it's not mentioned what version of rocket-tools is compatible/tested, so I use the latest tag 2023.05.02 of rocket-tools).
Due to the error I received while makeing rocket-chip, explained here, I needed to build rocket-tools on Ubuntu 23.10 (Mantic) with gcc-13 and g++-13.
I'm trying to run this script that installs all the prerequisites:

The only way I can successfully build rocket-tools is if I do this:
sudo apt install --yes gcc-11 g++-11
CC=gcc-11 CXX=g++-11 ./build.sh
However, while being successfully built with 11, rocket-chip doesn't like 11 and spits out an error requiring a newer version.
I'm completely at a loss. Any help that I could make these two work together would be highly appreciated.
UPDATE: I even pulled the latest branch from rocket-tools on Ubuntu 23.10 (Mantic):
git clone https://github.com/chipsalliance/rocket-tools.git ~/rocket-tools
cd ~/rocket-tools
git submodule update --init --recursive
export RISCV=~/riscv
echo 'export RISCV=~/riscv' >>~/.bashrc
./build.sh
I still get a different error:

In the build.sh and/or build-rv32ima.sh script you need to update the riscv isa.

I ran into the same issue and this is what fixed it for me.
