Undefined Symbol

[spazkat]

I'm trying to create a driver which accesses a program called Connects. When I build this driver, I get an error:

Undefined symbol '_Connect_ShowSWFP' referenced in "testDriver.c".

I have included the Connect.h file and the Connect.dll file which contain the function Connect_ShowSWFP function. What other reasons why this link error would occur.

Thanks ahead of time.

Hi Kat,

You need to include the DLL import library (.lib) for Connect.dll in your project, not the actual DLL. If you don't have one, you can create one by selecting Options >> Generate Import Library.  This command generates a DLL import library. LabWindows/CVI enables Generate DLL Import Library only when you have an include file in the Source window.

Thank you, that is exactly what was wrong 🙂
