Issue Details

When trying to build a Source Distribution from a LabVIEW project, I receive this error:

Error 7 occurred at Invoke Node in AB_Engine_Write_Linker_Wrapper.vi->AB_Build.lvclass:Copy_Files.vi->AB_Build.lvclass:Build.vi->AB_DepSourceDist.lvclass:Build.vi->AB_Engine_Build.vi->AB_Build_Invoke.vi->AB_Build_Invoke.vi.ProxyCaller 

Possible reason(s): 

LabVIEW: File not found. The file might be in a different location

Solution

This error can occur when LabVIEW finds multiple VI's with the same name, or a single VI saved in multiple locations on disk. 

To resolve this problem, ensure VI's are not saved in multiple locations, and all VI's have unique names. 

Additional Information

This issue is commonly referred to as cross-linking. Refer to the tutorial  Prevent VI Cross-linking with the Enhanced LabVIEW Project for more information on cross-linking and conflicts, and how to prevent and resolve them. 

Standard file names should not exceed 260 characters per the windows operating system, but it is recommended to keep them as short as possible.
