Request for instructions for cross-compiling onnxruntime for aarch64

[chiru-arh]

Hello,

I'm trying to cross-compile onnxruntime shared object for aarch64 on x86 machine. Kindly help me with the build instructions for it.

If you do not use cross-compiling, the instructions are mostly the same as x86.

See: https://onnxruntime.ai/docs/build/inferencing.html

@snnn , thanks for the reply..
I am planning to cross-compile onnxruntime for aarch64 on x86 machine. What are the steps for cross compilation

In the same document as shown above.

@snnn, I used the command ./build.sh --build_shared_lib --config MinSizeRel --arm64 --update --build for cross-compiling. However, this command generated .so for x86. libonnxruntime.so is generated in build/Linux/MinSizeRel/ folder. I used the file command in ubuntu to check the architecture and it printed
ELF 64 bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked
Am I missing anything?
