RISC-V GNU Compiler Toolchain

This is the RISC-V C and C++ cross-compiler. It supports two build modes: a generic ELF/Newlib toolchain and a more sophisticated Linux-ELF/glibc toolchain.

Getting the sources

This repository uses submodules, but submodules will fetch automatically on demand, so --recursive or git submodule update --init --recursive is not needed.

$ git clone https://github.com/riscv/riscv-gnu-toolchain

Warning: git clone takes around 6.65 GB of disk and download size

Prerequisites

Several standard packages are needed to build the toolchain.

On Ubuntu, executing the following command should suffice:

$ sudo apt-get install autoconf automake autotools-dev curl python3 libmpc-dev libmpfr
