Build error with pyrfc 2.4.2 on linux

[PartTimeSanta]

Good morning to all :)

I do have a little problem since some time now with installing pyrfc 2.4.0+ on linux and managed to get around it by using older versions but now I would really like to use the new versions - especially 2.4.2.

I'm using python3.8 in an venv environment on linux and try to install pyrfc 2.4.2 via pip3. As far as I do understand there are no wheels for this and so the "normal" way is to let pip build it from source.

I have the following installed:
python3.8
python3.8-dev

Cython==0.29.24
pip 21.3
setuptools 58.2.0

SAPnwrfcsdk750P_8 (as far as I can see the newest) installed
NWRFCSDK is set.

Unfortunatly my installation fails with the errors below.

As far as I do understand it seems to miss the type for RFC_SERVER_HANDLE. Any suggestions or ideas what I'm doing wrong ?
Thank you for any help in advance :)

Best wishes
