Is it possible to build static library of libOnnxruntime if somebody is aware? We are stuck. As per our business use case we can not use .so library. Feeling really stuck on the same.

This option is not available for all the configuration but it is possible to statically build onnxruntime: https://github.com/microsoft/onnxruntime/blob/main/tools/ci_build/build.py#L286C28-L286C44. The flag --build_shared_lib should not be part of the command line you are using the build onnxruntime.

You must be highlighting the python one. I want to build the c++ one of onnxruntime.

[xadupre]

The script is written in python but it is used to build any version of onnxruntime. The python build is enabled with option --build_wheel. If not present, python bindings is not built. It builds the full command line for cmake and then calls cmake.

[dsaneja]

The problem is that it creates lot of .a(static ) files/individual instead of one single static file. There should be one .a file as like .so

[xadupre]

It would require to change the cmake file to produce one file or maybe you can insert the command you need in the makefile to produce one. The list you need is defined here: https://github.com/microsoft/onnxruntime/blob/main/cmake/onnxruntime.cmake#L195.

@xadupre I managed to create a static onnxruntime library. Can you please tell me if it is possible to create a static version of onnxruntime with DirectML EP? If it's so, any hints would help me a lot.

[dsaneja]

@Xeetu : Can you please provide me the static build library somewhere. I shall be grateful to you.

[dsaneja]

any box link or google drive link whatever works best for you. Because I tried building onnxruntime library statically but no luck with me & my team so far.

[xadupre]

I assume you added --use_dml when running the command line or -Donnxruntime_USE_DML on the cmake command line. The options related to winml are written in cmake/winml.cmake. I assume this was written to link with a dll but it should be possible to modify it to link with a static library.

I'm curious, in what scenario would you be unable to use a .so file?
