Prebuilt RISC-V GCC Toolchains for Linux
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 ToolchainsToolchain prefix: riscv32-unknown-elf or riscv64-unknown-elf (see the individual releases) Release (tag) Download archive GCC binutils march mabi c-lib 🟢 rv32i-4.0.0 💾 download 12.1.0 2.39 rv32i ilp32 newlib 🟢 rv64imc-3.0.0 💾 download 12.1.0 2.39 multilib: rv32i rv32ic rv32im rv32imc ilp32 newlib 🟡 rv32i-2.0.0 💾 download 10.2.0 2.35 rv32i ilp32 newlib 🔴 rv32e-1.0.0 💾 download 10.1.0 2.34 rv32e ilp32e newlib 🟢 most recent 🟡 outdated 🔴 deprecated[back to top] Download⚠️ Cloning this repository (via git clone) will not include the release assets and will not include the actual toolchain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 BrowserClick 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 LineYou 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: wget https://github.com/stnolting/riscv-gcc-prebuilt/releases/download/rv32i-4.0.0/riscv32-unknown-elf.gcc-12.1.0.tar.gz[back to top] InstallationCreate 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/riscvNavigate 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/binTest the toolchain: $ riscv32-unknown-elf-gcc -v Using built-in specs.
