gcc-riscv-docker: a container image for compiling RISC-V 64

This repository contains a toolchain for building and running containers (i.e. with Docker or Podman) in order to compile and run RISC-V 64 in the container.

Usage

Building the container

The whole thing is built with make.

If you want to use Docker instead of Podman, adjust BUILDER in the Makefile.

# build the image
make build

# build the image without using cached results
make nocache

# export the image to gcc-riscv-docker.tar
make save

# delete the .tar
make clean

Using the container

An exemplary usage is in ./example, and there is a separate Makefile.

If you want to use Docker instead of Podman, adjust RUNNER in the Makefile.

To adjust which files are built, change COMPILE_FILES and COMPILE_OUT in the Makefile accordingly.

cd example

# compile main.c to main.o
make compile

# run main.o with spike and a proxy-kernel (pk)
make run

# just start a container and connect a shell (for inspection etc.)
# ATTN: The container is deleted, only the contents of the outside
# local directory will be kept
make login
