CVI 7.1.1

Link error:

undefined symbol _hp34401a_singleMeas

I get a total of 25 errors dealing with instruments.  This is on a system that at one time worked.  Not sure what all could have happened to the programs.  It appears that it is missing a library file.  Please let me know where I should look to eliminate this error.

Thanks,

Kevin

Agilent hp34401 driver  may be missing in your system. You may need to reinstall or lookout for the libraries correct location in the include path.

The CVI Plug and Play driver are typically gets installed (depending on NI-VISA version)

NI-VISA 4.1 and older installation paths were (source, DLL, libraries, headers):
C:\VXIPnp\WinNT\          

C:\VXIPnp\WinNT\Bin

C:\VXIPnp\WinNT\lib

C:\VXIPnp\WinNT\Include

NI-VISA 4.2 and newer, the installation paths are (source, DLL, libraries, headers) 

C:\Program Files\IVI Foundation\VISA\WinNT

C:\Program Files\IVI Foundation\VISA\WinNT\Bin

C:\Program Files\IVI Foundation\VISA\WinNT\lib

C:\Program Files\IVI Foundation\VISA\WinNT\Include

I have been able to get the program to compile.  Not sure why this is necessary and not part of the project file.

One was added by customize library menu and selecting the .fp file.  The I have to close the IDE and open back up for this to take effect.

The others I had to load instruments for the other .fp files.

Then I was able to compile and run the program successfully.

Not sure if this is a normal thing for the CVI 7.1.1 or not.
