LIN ncAction

[LeonSun65]

Hi,

I'm new to LabWindows/CVI. I installed LabWindows/CVI 2015. I didn't install any LIN and CAN related drivers so I might miss LIN and CAN protocal related drivers. When I tried to re-build a project someone else did, I got a bunch of errors. Here are two of them. The related code is LIN and CAN protocal code which sends and receive LIN and CAN messages.

 error: Undefined symbol '_ncAction@12' referenced in "c:\Users\lsun\Desktop\Projects\LabWindowsCVI\DUR-00012_SW_Labwindows_App_Shift_Actuator\cvibuild.DuraCVI\Debug\lin.obj". 

  error: Undefined symbol '_ncCloseObject@4' referenced in "c:\Users\lsun\Desktop\Projects\LabWindowsCVI\DUR-00012_SW_Labwindows_App_Shift_Actuator\cvibuild.DuraCVI\Debug\can2.obj". 

Here is the code in file lin.c which uses the function "ncAction",

            linStatus = ncAction (LINTxRx, NC_OP_START, 0);
            if (linStatus < 0)
                    {
                        linPrintStat(linStatus, "ncAction");
                        StopCallback (panel_LIN, PANEL_LIN_STOP, EVENT_COMMIT,
                        0, 0, 0);
                    }

Here is the code in file can2.c which uses the function "ncCloseObject",

        if (TXRXHandle!=0)
        {
            ncCloseObject(TXRXHandle);
        }
        QuitUserInterface (0);

I'm sure the code has no issue and it built without any issue in previous person's working enviorment. I think I just missed something in my working enviorment, maybe LIN and CAN drivers. Could anyone tell me what the possible causes are and how to fix them?

Thanks in advance,

Leon

Ni's CAN/LIN drivers can be found here:

I downloaded and installed the NI-XNET-15.0, but it still has the same build errors. I'm thinking maybe the Nican.h which I include is wrong. I got it from ...\\Program Files (x86)\National Instruments\NI-CAN\MS Visual C which comes from my previous LabVIEW 2012 package. Maybe I have to use different Nican.h and use some NiLin.h files which I don't have right now.

Problem solved. It turns out I need to install NI-CAN 15.0, not NI-XNET 15.0. Thank you samazing.
