Prebuilt RISC-V GCC Toolchains for Linux

Test_Toolchains license Gitter

The toolchains were built according to the instructions of the official RISC-V GNU Compiler Toolchain repository using Ubuntu on a 64-bit x86 machine (actually on Ubuntu on Windows). Most of the provided toolchains (the non-multilib versions) also support standard ISA extensions like A, C and M. These prebuilt toolchains are part of the NEORV32 RISC-V Processor project.

Available Toolchains

Toolchain prefix: riscv32-unknown-elf or riscv64-unknown-elf (see the individual releases)

⚠️ Cloning this repository (via git clone) will not include the release assets and will not include the actual toolchain archives! The compressed toolchain archives (.tar.gz) are available as releases assets only.

Via Browser

Click on the according download link in the table above to directly download the archive of choice from the according release page via the release assets.

Via Command Line

You can use wget to directly download a toolchain archive from the table above. Select the toolchain of choice, right-click on the "download" link, click "copy link address" and use that as argument for wget. Example:

Create a folder where you want to install the toolchain, for example /opt/riscv (you might need sudo to create this folder and copy data to it).

$ sudo mkdir /opt/riscv

Navigate to the download folder. Decompress your toolchain (replace TOOLCHAIN with your toolchain archive of choice). Again, you might have to use sudo if your target directory is protected.

$ sudo tar -xzf TOOLCHAIN.tar.gz -C /opt/riscv/

Now add the toolchain's bin folder to your system's PATH environment variable. Your can also add this line to your .bashrc if applicable.

$ export PATH=$PATH:/opt/riscv/bin

Test the toolchain:

$ riscv32-unknown-elf-gcc -v
