Following the tutorial i have build libraries from sources until beta 3.0.0 without errors. VS2008 'should' be correctly configured, but versions > 2.3.0 give me problems at linking time in any test i try. Before trying to solve this problem by myself i should be sure that problem is solvable with my hw/sw resources [or that is not a compiler limit? or OS limit (i use XP) or Guido's limit ;-) ] Tanks in advance and sorry for my real poor english!
