Compiling 'Clue' from BeUnited's cvs I found that it expects B_ATOM_TYPE and B_ATOMREF_TYPE. http://zeta-os.com/cms/custom/API/d6/d6e/TypeConstants_8h.html B_ATOM_TYPE = 'ATOM', B_ATOMREF_TYPE = 'ATMR', B_ASCII_TYPE = 'TEXT' Not sure what these are. Would it be worthwhile to add them to Haiku's TypeConstants.h? /Jonas Sundström.
