Run RISC-V assembler programs on Debian Linux

This tutorial shows how to compile and run RISC-V assembler code on Debian Linux systems, which are not running on a RISC-V system (e.g. x86_64).

Install the toolchain and emulator

sudo apt-get install qemu qemu-system-misc qemu-user gcc-riscv64-unknown-elf

Create a hello world program

Save this as hello.s:

# ChatGPT result of this question:
# write a Python script, where the user can move a sprite with cursor keys, using PyGame

import pygame

# Initialize PyGame
pygame.init()

# Set up the screen (width, height, caption)
size = (700, 500)

# library installation:
# pip3 install -U selenium
# pip3 install webdriver-manager
#
# usage:
# first start Chrome in debug mode:
#   google-chrome --remote-debugging-port=1234
# then:
#   - sign in to MetaMask and select right network and account
#   - connect to OpenSea

# first create an API key at coinmarketcap.com. It is free for personal use. Set it in a variable:
export API_KEY="11111111-1111-1111-1111-111111111111"

# now you can call the API with curl, and extract the result with jq
# for example to get the quote for a crypto currency in USD:
coinquote() {
    curl -s -H "X-CMC_PRO_API_KEY:$API_KEY" -H "Accept:application/json" \
    -d "symbol=$1&convert=USD" \
