You must recompile. First you compile Chicken 4 with your old Chicken 3, but then you need to make clean and compile Chicken 4 with Chicken 4 again. This has something to do with the fact that the old macro hooks system does not exist anymore, but chicken 3 generates code to match its own version of libchicken, which does still have those macro hooks. Felix can probably explain better ;) HTH, Peter -- http://sjamaan.ath.cx -- "The process of preparing programs for a digital computer is especially attractive, not only because it can be economically and scientifically rewarding, but also because it can be an aesthetic experience much like composing poetry or music." -- Donald Knuth
