The official GNU toolchain for RISC-V, providing GCC-based C and C++ cross-compilers. It can build bare-metal ELF toolchains (Newlib/Picolibc) or Linux ELF toolchains (glibc, musl, or uClibc).

Use cases

• cross-compile C/C++ programs for RISC-V
• build a bare-metal toolchain for RISC-V microcontrollers
• build a Linux userspace toolchain for RISC-V with glibc or musl
• compile operating systems or firmware targeting RISC-V
• set up a RISC-V development environment on Linux or macOS

When to choose

• you need a GCC-based compiler targeting RISC-V
• you are developing firmware, kernels, or Linux software for RISC-V hardware
• you want the canonical, actively maintained RISC-V GNU toolchain

When to avoid

• you need a lightweight toolchain without a multi-GB source download and build
• you target architectures other than RISC-V
• you prefer LLVM/Clang-based tooling for RISC-V
