Hello,

I am trying to build a class locally with interFoam.

I tried to follow this example : How to add a new class locally
However, the issues discussed were not resolved in that thread.

I will paste the code here, and try to explain what are the difficulties.

.H file

#ifndef chnl_H
#define chnl_H
#include<list>

namespace Foam{
class chnl
{
        private:
                int chNo;
                Foam::labelList locProc;
        public:
                chnl(int a);
                int disp();
                Foam::labelList getlocProc (Foam::labelList& gL);
};
}

.C file

#include "chnl.H"
#include<list>
//CONSTRUCTER
Foam::chnl::chnl(int b) : chNo(b) {}

int Foam::chnl::disp() { return chNo; }

Foam::labelList Foam::chnl::getlocProc (Foam::labelList& gL)
                {
                        locProc = gL;
                        return locProc;
                }

And here is the error:

chnl.H:11:9: error: ‘labelList’ in namespace ‘Foam’ does not name a type
   Foam::labelList locProc;
         ^~~~~~~~~
chnl.H:17:9: error: ‘labelList’ in namespace ‘Foam’ does not name a type
   Foam::labelList getlocProc (Foam::labelList& gL);
         ^~~~~~~~~
chnl.C:10:7: error: ‘labelList’ in namespace ‘Foam’ does not name a type
 Foam::labelList Foam::chnl::getlocProc (Foam::labelList& gL)
       ^~~~~~~~~

Initially, I used just labelList (and not Foam::labelList), but after reading some topics on StackOverflow I tried to use Foam::labelList still no success.

Can anyone point out what am I missing here?

Thanks

Did you include the appropriate OpenFOAM headers?

[ashishmagar600]

Thanks a lot.

I thought using "Foam::type" would do the thing, but after your suggestion, I check Doxygen how they have used any class with "Foam::labelList". I found out I was missing

#include "ListOps.H"
#include "labelRange.H"

This problem is solved.

Thanks.

Hello ashishmagar600,
could you help me

I'm facing similar problem , however i tried to search for headers ,but all of them failed ,

when i implement the following code

const volScalarField::GeometricBoundaryField& pbf = p.boundaryField();

i got the similar error does not name a type


createFields.H:19:23: error: ‘GeometricBoundaryField’ in ‘Foam::volScalarField {aka class Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>}’ does not name a type
const volScalarField::GeometricBoundaryField& pbf = p.boundaryField();
