⁠PULP RISC-V GNU Compiler Toolchain

This Docker image contains the compiled PULP RISC-V GNU compiler toolchain.

⁠How to use this image

In your project, create a shell script for the RISC V compiler executable. You can name the file riscv32-unknown-elf-gcc which is the exact name of the RISC V compiler executable inside the Docker container. Put the following content inside of it.

#!/bin/sh
docker run --rm --entrypoint riscv32-unknown-elf-gcc --volume $PWD:/hostdir coderitter/pulp-riscv-gnu-toolchain "$@"

This call to docker run will create a temporary Docker container with the current directory mounted into Docker container. It then executes the RISC V compiler executable and forwards any parameters which were made when the script was executed.

The last step is to set the permission of the file so that is executable.

chmod a+x riscv32-unknown-elf-gcc

Now you can use the script as if the compiler itself was installed in your host system.

./riscv32-unknown-elf-gcc -std=c99 -march=rv32imfdcxpulpv2 src -o build/firmware

You can also head to the Coderitter GitHub repository⁠ which contains ready-to-use shell script files including the one of this example.

⁠Directory structure and files

The PULP RISC-V GNU compiler toolchain is located in the directory /opt/riscv. The PATH variable is set to /opt/riscv/bin which contains all the RISC-V GNU compiler tools in executable form. Neither the source code of PULP RISC-V GNU compiler toolchain nor the required dependencies to compile it are included in this image.

⁠Environment variables

There are no environment variables that could be used for configuration.
