Help Building 32bit pyrfc

[josephkirby]

I need help building a 32bit version of pyrfc. I have the latest version of Build Tools installed. I have python 32bit installed. And I have 32bit SAP GUI 8.0 installed. What do I need to do to build pyrfc?

[bsrdjan]

Here are Requirements

[josephkirby]

That doesn't answer the question. What are the steps to build the 32bit version?

[bsrdjan]

Steps are the same as for 64 bit version, only the 32 bit Python and 32 bit SAP NW RFC SDK shall be used.

The 32 bit pyrfc can be built on 64 or 32 bit operating system, supported by SAP NW RFC SDK (see https://me.sap.com/notes/2573790).

Compiler options are in same SAP OSS note where 64 bit options are provided https://me.sap.com/notes/2573953

I am getting this error now:

I got that fixed and now I'm getting a whole bunch of errors. Not sure what to do.

Could someone build the 32bit wheel for me?

[bsrdjan]

PyRFC 32bit version is not maintained any more and build options need to be investigated. If build support needed, please create customer ticket for BC-MID-RFC-SDK component and refer to this GH issue.

The build command, as described in README, might help: https://github.com/SAP/PyRFC?tab=readme-ov-file#download-and-installation. In case of issues, delete cpp files from source folder and re-test

python -m build --wheel --outdir dist

I'm making some progress but still getting errors. Can you assist?
