Hi - this looks like a preprocessor error, which I have not seen before. Is this a very new version of the nwrfcsdk that you are using?

itnazeer commented 6 years ago

Yes, this is the new version

OK - so I don't have access to an SAP system or the latest SAP NW RFC SDK, so I cannot see what is causing this. You could try obtaining an older (eg: 12 month old) version of the SDK and see if that will work. If we can work out at which version of the SDK things have changed, then we could do a diff between the two to figure out how the preprocessor step needs to be updated. The preprocessor is performed by the u16lit.pl script in the tools directory. This is a script that was provided by SAP many years ago, so maybe there is something there that should be updated.

Please share the old version sdk url such that I will work on it.

I am curious. Why do you use python-sapnwrfc and not https://sap.github.io/PyRFC/ ?

Agree also, pyrfc for future implementations. Use Piers' connector for Ruby though as I do not know of a pyrfc equivalent for that language.

The problem is that you very likely use an old compiler which defaults to C99. String literals were improved a lot in C11 especially for unicode strings so you need to use gcc 4.6+ and need to tell it to use C11 by adding "-std=c11". gcc 5.1+ already defaults to C11.
