Hi @mottioh / @anonymous15,
so, with the former post being marked as solution you got mk_sap running successfully? Our former trials ended without any goal due to the very old version of sapnwrfc-0.19 that was basically used in mk_sap. Same with nwrfcsdk which sounds obligatory according to the mk_sap header.
I wonder if and how you have installed these two mentioned. Would be great if you could share some information about that.
