unresolved external symbol _LinearFitEx@44 referenced in function

[toma908]

I get this error when building in VS 2010 as a converted CVI project.

It builds without errors in CVI using LabWindows/CVI project.

LinearFitEx is a function from the Advanced Analysis library. As far as I know you have to buy/install Measurement Studio to make this library available for VS.

You don't need Measurement Studio, but the analysis libraries have to be included in the project, one way or another. In modern versions of CVI they (analysis.lib, regenlys.lib) can be found in:

%ALLUSERSPROFILE%\National Instruments\CVI<version>\extlib\msvc (32-bit version) or

%ALLUSERSPROFILE%\National Instruments\CVI<version>\extlib\msvc64 (64-bit version)

Thanks for the help

The VS project does include reganlys.lib but not analysis.lib.

Also only reganlys.lib is in the path specified below.

I don't think it is an installation issue since it builds as a labwindows/cvi project.

[msaxon]

So have you tried including analysis.lib, as I suggested?

[toma908]

I don't have analysis.lib only reganlys.lib

There is one thing I do not understand, how can you use a function from the Advanced Analysis Library without having the Advanced Analysis Library?
