Implement PosixEnv::GetRuntimePath to enable AutoEP tests on Linux/MacOS #26424
Conversation
We try to follow the implementation of WindowsEnv which resolves the runtime directory as the directory of the current DLL (onnxruntime) or executable for static linkage.
The same symbols are already exposed for Windows. This enables the CUDA EP to be selected in AutoEP tests.

I saw that returning an absolute vs an relative path makes a difference on whether ORT will attempt to call CreateEp which CUDA EP does not implement.

this enables the autoep test cases. The exports are already present on Windows.

I don't have a Mac to test. Can this be deferred to another PR? It is not required for the tests as the tests use libonnxruntime.dynlib

You may directly use std::filesystem::path. The class PathString was created before we migrated the code to C++17.

Thanks! Wasn't aware of this. Will close this one then! |

Description
During #26210 we discovered that implementing
PosixEnv::GetRuntimePathis a requirement to make autoep test work on Linux.This PR implements PosixEnv::GetRuntimePath in a way that is close to Windows on Linux and (partially) on MacOS. The newly added method is tested by enabling autoep tests on Linux and MacOS.
