We prove a linear version of Dawson-Gärtner theorem: weak large deviation principles and the equality −s = p* between the negentropy and the Fenchel-Legendre transform of the pressure are preserved through linear projective limits. As a result, the equality −s = p* holds in great generality for empirical means of independent and identically distributed random variables (Cramér's theory), e.g. in any measurable normed space, and even in any projective limit of such spaces. Eventually, we give an original example where −s is different from p* and discuss the dual equality.
