compile error: "...does not name a type "?
 

I am trying to compile a PCG solver and get errors about "does not name a type"

clFOAM.H:41:19: error: ‘dictionary’ does not name a type
const dictionary& solverControls,
^
clFOAM.H:57:19: error: ‘dictionary’ does not name a type
const dictionary& solverControls,
^
clPCG.C:39:18: error: ‘solverPerformance’ in ‘class Foam::lduMatrix’ does not name a type
Foam::lduMatrix::solverPerformance Foam::clPCG::solve

What does it mean? The code is from an older OF version so maybe that's causing the problem.
