Pre-compiled RISC-V GNU toolchain and spike

mardi 17 septembre 2019

This is a precompiled version of the RISC-V GNU toolchain (gcc, as, ld, libc, ...) and spike simulator, generated from the sources https://github.com/riscv/riscv-gnu-toolchain and https://github.com/riscv/riscv-tools, with executables stripped to save disk space (the extracted /opt/riscv/ directory uses around 2 GB of disk space). It also contains ANTLR4, Python 3.11 and Pyright, for use in the MIF08 and CAP courses.

Older release, for 20.04, 20.10

An old version is still available in riscv-2022.tar.zx.

Current version for Ubuntu 22.04 & 24.04

It was generated and tested on Ubuntu 22.04, tested on Ubuntu 24.04, and may or may not run elsewhere. Other versions are available on this page. Use at your own risk.

This archive needs to be extracted in /opt/ and will create directories /opt/riscv, /opt/python, /opt/pyright, and /opt/bin directory to add to your $PATH :

wget 'https://matthieu-moy.fr/spip/IMG/xz/riscv.tar.xz' -O /tmp/riscv.tar.xz

cd /opt/

sudo tar -xJvf /tmp/riscv.tar.xz

The device-tree-compiler and libmpc3 packages need to be installed for spike to work. On Ubuntu, run :

sudo apt install libmpc3 device-tree-compiler

After installation, you can delete the file /tmp/riscv.tar.xz.

Executables are available in /opt/bin (some are symlinks to real executables stored somewhere else), which you need to add to your $PATH (in ~/.bashrc) :

PATH=/opt/bin:"$PATH"

Quick test to check that the toolchain is working :

echo '#include <stdio.h>' > /tmp/foo.c; printf 'int main() {printf("Hello");}' >> /tmp/foo.c; riscv64-unknown-elf-gcc /tmp/foo.c -o /tmp/foo; spike pk /tmp/foo; echo; pyright --version

Must output :

bbl loader

Hello

pyright 1.1.339

If this works, you can stop reading here.

Uninstallation

If you want to uninstall the toolchain, run (as root) :

rm -fr /opt/riscv/ /opt/node-v14.17.3-linux-x64/ /opt/bin/pyright

Fedora 38

This archive was generated on Fedora 38, but is meant to be as self-contained as possible, it is likely to work on other systems. GCC should work regardless of the place where the archive is extracted, but spike pk won’t find pk nor the dtc executable unless the archive is extracted in /home/tpetu/Enseignants/matthieu.moy/mif08/. This assumes you have permission to write to /home/tpetu/Enseignants/matthieu.moy/, use sudo if needed.

wget 'https://matthieu-moy.fr/spip/IMG/xz/riscv-fedora.tar.xz' -O /tmp/riscv-fedora.tar.xz

mkdir -p /home/tpetu/Enseignants/matthieu.moy/mif08/

cd /home/tpetu/Enseignants/matthieu.moy/mif08/

tar -xJvf /tmp/riscv-fedora.tar.xz
