MRISC32 GNU toolchain

This is a top level repository for building the MRISC32 GNU toolchain.

The toolchain consists of:

C and C++ compilers (GCC)
Assembler, linker, ELF tools etc (binutils)
A standard C library (newlib)

Pre-built binaries

The latest pre-built version of the toolchain can be found here.

Binaries are available for:

Linux (x86_64)
macOS (ARM64 + x86_64)
Windows (x86_64)

Some releases also have pre-built versions for Linux ARM32 and/or ARM64 (e.g. for Raspberry Pi).

Installation

Unpack the archive to a location of your choice.
Add path/to/mrisc32-gnu-toolchain/bin to your PATH environment variable (e.g. in $HOME/.bashrc on Linux).

Building yourself

Currently there are two methods for building the toolchain:

Natively on your host machine (recommended).
Using Docker.

Host build

The build has been tested on Ubuntu 20.04 (with GCC), macOS (with clang) and Windows (with MSYS2 and MinGW), but may work on other similar systems too.

Prerequities

The following packages are required (example given for Ubuntu):

sudo apt install bison build-essential curl flex texinfo

Building

To build and install the GNU toolchain for MRISC32, do (example given for Ubuntu):

git submodule update --init --recursive
./build.sh --clean --prefix="$HOME/.local"

For more options, see:

./build.sh --help

Docker build

The Docker based build will produce a toolchain for Linux hosts.

Prerequities

Install Docker.

Building

To build the GNU toolchain for MRISC32, do:

git submodule update --init --recursive
./build-in-docker.sh

The result is placed in the out/install folder. You can create a tar archive of the folder contents, or add out/install/bin to your PATH.
