Can you tell me pls if i'm missing anything here? I followed the guide in the pdf documentation, and also i've read: (http://help.sap.com/saphelp_nwpi71/helpdata/en/22/0430ba488911d189490000e829fbbd/frameset.htm) / NetWeaver RFC SDK/Programming with the NW RFC API/Working with the NW RFC SDK Files

I'd be grateful for any kind of help.

Was it helpful?

Solution

I had the same issue. Make sure you are compiling to the OS, not the chip. If the OS is 32-bit, use the 32 bit compile/link options found here, if the chip and OS are 64-bit, follow the instructions for the 64-bit entry:
