Undefined external error message

Borland C++ Version 5
NIDAQ 7.5 with PCI-6503 on WinXP
Have nidaqmx.lib and nidaqmx.h files.

Every call to NIDAQ comes up with "Undefined External" during the linking.
I've looked up every topic on this I could find.
Do you have a nidaqmx.obj file instead of a nidaqmx.lib file?
Or some modification to the .h or .lib file?

I have read Document 0HMI568Z.
--Both solutions were tried and do not help.
--I question solution #1
----for changing compile options on a linking problem
--I question solution #2
----Having only the #ifdef that line does nothing
----There should be a closing #endif to avoid
----"Unexpected end of file in conditional started..."
----My nidaqmx.h file already checks __cplusplus
