Problem with lsb: LABVIEW.LIB was not called from a LabVIEW process

[Chevengur]

I've decided to compile the Zero Phase Shift.vi filter into a dll. This vi relies on IIR.lsb and IIR.c files.

There is no problems with running the vi itself. However, using  a dll that was built from this vi  generates a fatal Windows error message

LABVIEW.LIB was not called from a LabVIEW process (for example, if one tries to call the dll from within a VB program)

If I remove the lsb reference from the vi, then calling the dll has no problems. I have tried to reference the IIR.lsb explicitly from the Build Shared Lib wizard, that did not work.

I used LabVIEW 7.1
