I've been trying to build and run rocket-chip on Ubuntu for days and failed to understand what I'm doing wrong.
Following all the README files recursively (starting from rocket-chip v1.6 all the way back to basic apt install build-essential), I ended up with the script rocket-chip.jammy.sh for Ubuntu 22.04 (Jammy).
After running the script, in the make command under ~/rocket-chip/simulator, I get the following error:
<logs-trimmed-up-to-here>

I initially thought that it's because Ubuntu 22.04 ships with gcc-11 and g++-11. So, I tweaked my script to make it run for Ubuntu 23.10 (Mantic), the full script at rocket-chip.mantic.sh.
Worth noting that I had to build rocket-tools with gcc-11 and g++-11 as with the already installed 13 I had another issue.
CC=gcc-11 CXX=g++-11 ./build.sh
I still get the same error, so very likely it's the rocket-tools that was built by/for ♂️ gcc-11 and g++-11 and, therefore not compatible with rocket-chip.
Anyone spots any missing packages? What am I doing wrong?
