I'm trying to compile the companyClient.c in a visual studio 2010 project, but even if I link properly to the library sapnwrfc.lib I still get several unresolved externals:
Error 1 error LNK2019: unresolved external symbol _RfcCloseConnection@8 referenced in function _errorHandling C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 2 error LNK2019: unresolved external symbol _RfcSAPUCToUTF8@24 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 3 error LNK2019: unresolved external symbol _RfcDestroyFunction@8 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 4 error LNK2019: unresolved external symbol _RfcGetString@24 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 5 error LNK2019: unresolved external symbol _RfcGetStructure@16 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 6 error LNK2019: unresolved external symbol _RfcInvoke@12 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 7 error LNK2019: unresolved external symbol _RfcSetChars@20 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 8 error LNK2019: unresolved external symbol _RfcCreateFunction@8 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 9 error LNK2019: unresolved external symbol _RfcGetFunctionDesc@12 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 10 error LNK2019: unresolved external symbol _RfcOpenConnection@12 referenced in function _nlsui_main C:\Users\Attila\Desktop\SAP_NWR_RFC\SAP_NWR_RFC\companyClient.obj SAP_NWR_RFC Error 11 error LNK1120: 10 unresolved externals C:\Users\Attila\Desktop\SAP_NWR_RFC\Debug\SAP_NWR_RFC.exe SAP_NWR_RFC
Can you tell me please 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.
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:
