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. The latter is also the basis for the RISC-V Akaros cross- compiler, which is kept separately in the Akaros repository.

To build the Newlib cross-compiler, pick an install path. If you choose, say, /opt/riscv, then add /opt/riscv/bin to your PATH now. Then, simply run the following command:

./configure --prefix=/opt/riscv
make

You should now be able to use riscv-gcc and its cousins.

To build the Linux cross-compiler, pick an install path. If you choose, say, /opt/riscv, then add /opt/riscv/bin to your PATH now. Then, simply run the following command:

./configure --prefix=/opt/riscv
make linux
