External functions without arguments are not found

[Alexander.Roehnsch]

Hi,

I tried the ExternalLibraries example from the User Guide in the testmodels 
directory of the 1.4.4 release.
It worked fine.

Then I wanted to change one function to take no arguments. That didn't work. 
Did I do something wrong or is this a bug? Description follows.

Regards,
Alexander


I changed ExternalFunc1_ext() to take no arguments. Changed all the signatures 
and implementations. Like in the C file:

        double ExternalFunc1_ext()
        {
          return 2;
        }

And in the model:

        function ExternalFunc1
          output Real y;
          external y=ExternalFunc1_ext()
                annotation(Library="libExternalFunc1_ext.o",
                Include="#include\"ExternalFunc1_ext.h\""); 
        end ExternalFunc1;

With a later call to:

        der(x)=-ExternalFunc1();

Running the script gives off:

        >> runScript("ExternalLibraries.mos")
        "true
        0
        0
        record
            resultFile = "Simulation failed.
        No matching function found for ExternalFunc1() of type function() =>
        Real, candidates are function() => Real
        Error occured while flattening model ExternalLibraries
        "
        end record

        true"
