Getting Started with RuyiSDK

Install the required packages

sudo apt update; sudo apt install -y wget tar zstd xz-utils git build-essential

Install the ruyi package manager (see the official installation guide for other methods)

wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.51.0/ruyi-0.51.0.riscv64
chmod +x ./ruyi-0.51.0.riscv64
sudo cp -v ./ruyi-0.51.0.riscv64 /usr/local/bin/ruyi

Install the GCC and LLVM toolchains

ruyi update

ruyi install gnu-ruyisdk llvm-ruyisdk

Hello World (GCC)

Create and activate the ruyi virtual environment (GCC)

ruyi venv -t gnu-ruyisdk manual venv-gnu-ruyisdk-k3-pico-itx

. venv-gnu-ruyisdk-k3-pico-itx/bin/ruyi-activate

Verify the GCC version

riscv64-ruyisdk-linux-gnu-gcc -v

Compile and run Hello World (GCC)

cat << EOF > hello.c
#include <stdio.h>
int main() {
printf("Hello, World!\n");
return 0;
}
EOF
riscv64-ruyisdk-linux-gnu-gcc hello.c -o hello-gcc
./hello-gcc

Normally, the terminal displays output similar to the following:

Hello, World!

Exit the ruyi GCC virtual environment

ruyi-deactivate

Hello World (LLVM)

Create and activate the ruyi virtual environment (LLVM)

ruyi venv -t llvm-ruyisdk manual --sysroot-from gnu-ruyisdk venv-llvm-ruyisdk-k3-pico-itx

. venv-llvm-ruyisdk-k3-pico-itx/bin/ruyi-activate

Verify the LLVM version

clang -v

Compile and run Hello World (LLVM)

clang hello.c -o hello-llvm; ./hello-llvm

Normally, the terminal displays output similar to the following:

Hello, World!

Exit the ruyi LLVM virtual environment

ruyi-deactivate
