Build Failure: pyo3-ffi v0.20.3 - SOABI not found in sysconfigdata file

[Sangeetha-E]

I'm encountering an issue when trying to compile the pyo3-ffi v0.20.3. The build fails with the following error:

Error logs:

I am looking for guidance on how to resolve this build issue. Any help or suggestions would be greatly appreciated.

What's the output of python3 -m sysconfig? Can you find SOABI in it?

Yes. I found SOABI.

$ python3 -m sysconfig | grep SOABI
	ALT_SOABI = "0"
	SOABI = "cpython-311-x86_64-linux-gnu"

Note: I am cross compiling pyo3-ffi.

What target are you cross compiling to? Are you able to try latest PyO3 (0.22.2)? We might have improved things (or at least improved error messages), and if it's still a problem maybe we can improve the error message further.
