RuyiSDK Getting Started Example

Install dependencies

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 toolchain/gnu-ruyisdk manual venv-gnu-ruyisdk
 
. venv-gnu-ruyisdk/bin/ruyi-activate

Verify the GCC version

riscv64-ruyisdk-linux-gnu-gcc -v

Compile Hello World (GCC)

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

Run the generated file

./hello-gcc

Under normal circumstances, the terminal displays output similar to:

«Ruyi venv-gnu-ruyisdk» ubuntu@ubuntu:~$ ./hello-gcc
Hello, World!
«Ruyi venv-gnu-ruyisdk» ubuntu@ubuntu:~$

Exit the ruyi GCC virtual environment

ruyi-deactivate

Hello World (LLVM)

Create and activate the ruyi virtual environment (LLVM)

ruyi venv -t toolchain/llvm-ruyisdk manual --sysroot-from gnu-ruyisdk venv-llvm-ruyisdk
 
. venv-llvm-ruyisdk/bin/ruyi-activate

Verify the LLVM version

clang -v

Compile Hello World (LLVM)

clang hello.c -o hello-llvm

Run the generated file:

./hello-llvm

Under normal circumstances, the terminal displays output similar to:

«Ruyi venv-llvm-ruyisdk» ubuntu@ubuntu:~$ ./hello-llvm
Hello, World!
«Ruyi venv-llvm-ruyisdk» ubuntu@ubuntu:~$

Exit the ruyi LLVM virtual environment

ruyi-deactivate
