Building the Runtime Library

Linux (X86_64 and AARCH64)

bash runtime-library/build-runtimes.sh            # both platforms
bash runtime-library/build-runtimes.sh X86_64     # single platform
bash runtime-library/build-runtimes.sh AARCH64

Outputs: runtime-library/artifacts/runtime-library-{ARCH}.tar.gz

Windows

cd runtime-library
.\build-runtime.bat

Prerequisites

Toolchains must be installed in /opt/:

• X86_64: /opt/x86_64-unknown-linux-gnu-gcc-9.5.0/
• AARCH64: /opt/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/

Run sudo bash scripts/setup-env.sh if toolchains are missing.

Key Build Flags

• X86_64: -march=haswell -fopenmp -Ofast -s
• AARCH64: -fopenmp -Ofast -s
• Both use -fno-math-errno

Troubleshooting

• If CMake can't find the toolchain, verify /opt/ paths match runtime-library/CMakeLists.txt
• If ONNX Runtime symbols are missing, check runtime-library/deps/onnxruntime/ has the right arch subfolder
• Build artifacts go to runtime-library/artifacts/ — never to build/ directly
