Yade-OpenFOAM icoFoam coupling

Hello. I am trying to run the icoFoamYade example given in the repository. Software and OS characteristics are as follows:

1. Ubuntu 20.04.
2. Python 3.8.5.
3. Yade version 2020.01a.
4. OpenFOAM v8.

I have been following each step written in the example. In the fourth step, which states to enter in the directory "Yade-OpenFOAM-coupling" and execute commands ./Allclean and ./Allwmake fails with these two error messages for both icoFoam and pimpleFoam examples.

1. icoFoam:

error: 'class Foam::fvMesh' has no member named 'SOLVER'; did you mean 'Foam::dictionary Foam::solution::solvers_'? (not accesible from this context)
125 | pEqn.solve(mesh.solver(p.select(piso.finalInnerIter())));

2. pimpleFoam:

fatal error: singlePhaseTransportModel.H: No such file or directory.

I have been working around through both errors and noticed that if I access to the icoFoamYade.C and comment line 125, the error "stops". Of course, it should not make any sense. In the case of the pimpleFoam error, if I paste the corresponding files to the directory ./openfoam8/src/Osspecific/PO/lnInclude, then more files references are asked until a final error is shown.

I am more interested in running the icoFoamYade example. Any help will be appreciated.
