Akaria RISC-V GNU toolchain

About

This repository provides some makefiles to build GNU toolchains (binutils, GCC, C libraries) easily for NSITEXE Akaria RISC-V processors.

If you just want to use GNU toolchains, please download TAR archives from "releases" page.

How to use

Just run "make install". This command will download source codes from suitable repositories and configure and build automatically. It will take long time (over an hour or more) and need large disk space (> 30GB).

$ make install

You can specify a PARALLEL option to build more faster if you use multi-core CPU. In this sample (PARALLEL=16) means that make will invoke up to 16 commands in parallel.

$ make install PARALLEL=16

This command will generate some directories that has name "riscv64-*" if build procedures finished successfully.
