Hey,

I try to compile a code which used to compile in OF 2.3, but in version 4.1 it doesn't do so any more. I receive the error: no matching function for call to gSum... (see below) Does anyone know if a gSum function is relocated or removed in the latest OF? Many thanks in advance!

The piece of the code which the error is called from is as follows:

#include "pollutant.H"
#include "fvCFD.H"
#include "IOmanip.H"

void pollutant::balance()
{
    forAllConstIter(HashTable<isotope*>, isotopes_, iter)
    {
        const isotope& nuclide = *iter();
        const volScalarField& Ci = nuclide.C();
        Info << "Total amount of " << Ci.name()
             << " in the system: " << gSum(Ci.internalField()*mesh_.V()) 
	     << endl;
    }
}

The complete error message is the following:

pollutant.C: In member function ‘void Foam::pollutant::balance()’:
pollutant/pollutant.C:443:72: error: no matching function for call to ‘gSum(Foam::tmp<Foam::DimensionedField<double, Foam::volMesh> >)’

                                                                        ^

If you run

git grep gSum

in the OpenFOAM-dev repository, you will find that OpenFOAM still uses gSum().
I assume that the necessary headers changed, have a look on current code which uses gSum().

Hi,

pollutant/pollutant.C:443:72: error: no matching function for call to ‘gSum(Foam::tmp<Foam::DimensionedField<double, Foam::volMesh> >)’

Well, error is rather self-explanatory. * operation returns tmp object, gSum can not operate on tmp objects. You need either to dereference tmp using () operator, so your call becomes something like:

gSum((Ci.internalField()*mesh_.V())())

or you can try to create volScalarField from tmp before doing gSum.

Hey Alexey and Gerhard,

Thank you both for your answers. The dereferencing with the () operator worked. So, special thanks to you Alexey! Nice solution
