Dear Foamers,

I am trying to create an IOList of labelListLists:

    List<labelListList> dummyLabelListListList(0);

    IOList<labelListList> testList
    (
        IOobject
        (
            "dendriteCellNeighbours",
            runTime.timeName(),
            mesh,
            IOobject::READ_IF_PRESENT,
            IOobject::AUTO_WRITE
        ),
        dummyLabelListListList
    );

Compiling this throws the following error:

Make/linux64GccDPOpt/testApp.o: In function `Foam::IOList<Foam::List<Foam::List<int> > >::IOList(Foam::IOobject const&, Foam::List<Foam::List<Foam::List<int> > > const&)':
/opt/openfoam231/src/OpenFOAM/lnInclude/IOList.C:116: undefined reference to `Foam::IOList<Foam::List<Foam::List<int> > >::typeName'
Make/linux64GccDPOpt/testApp.o: In function `Foam::IOList<Foam::List<Foam::List<int> > >::type() const':
/opt/openfoam231/src/OpenFOAM/lnInclude/IOList.H:60: undefined reference to `Foam::IOList<Foam::List<Foam::List<int> > >::typeName'
collect2: error: ld returned 1 exit status

Does anyone have any idea, what the problem could be?

Thanks in advance,
oswald
