  We discuss a general strategy to compute the coefficients of QCD chiral
Lagrangian by using the lattice regularization of QCD with Wilson fermions.
This procedure requires the introduction of an effective Lagrangian for lattice
QCD as an intermediate step in the calculation. The continuum QCD chiral
Lagrangian can be then obtained by expanding the lattice effective Lagrangian
in increasing powers of the external momenta. A suitable renormalization
procedure is required to account for the chiral symmetry breaking introduced by
the Wilson term in the lattice action. In anticipation of a numerical
simulation, the lattice effective Lagrangian is computed analytically and
investigated in the strong coupling and large $N$ limit
