fail to build onnxruntime_tidl (cross-compilation arm64) from windows

[habibbenayed]

Hello Team,

I'm facing an issue while trying to build ONNX Runtime on Windows. The command I'm using is:

python build.py --build_dir build/windows --config Release --build_wheel --update --arm64 --parallel --skip_tests --skip_onnx_tests --use_tidl --compile_no_warning_as_error --cmake_generator "Visual Studio 17 2022"

The build process fails with the following error:

error C1083: Cannot open include file: 'dlfcn.h': No such file or directory

Even when I remove --arm64 and --update to check the .whl output, I still encounter the same error.

After investigating, I found that dlfcn.h is typically used on Ubuntu/Linux and not on Windows. Could this be an issue with the build configuration? Has anyone encountered this before or knows a workaround?

Thanks in advance!

Can you try using build.bat? For example
.\build.bat --config Release --build_shared_lib --parallel --skip_submodule_sync --skip_tests --compile_no_warning_as_error --build_wheel
