Apart from stopping on some syntax errors before the 'EXPORTS' section (that I corrected by removing most lines before EXPORTS) : 1) If I keep only the SQLAllocConnect@8 then linking goes OK, but at runtime : linked against not existing SQLAllocConnect@8 2) If I keep only SQLAllocConnect, then linking fails ... 3) If I keep the whole stuff, then the same as 1. My (restricted knowledge) is : 1) the object code calls _SQLAllocConnect@8 (just by construct : function f -> _f@stacksize) 2) The import library MUST have this function in it. So in my case _SQLAllocConnect@8 must be in the import 3) The DLL expects _SQLAllocConnect as function call, which is proven by my manipulation via assembly. Changing the _f@ by _f does really the job ! 4) Somewhere the equivalence between both should be declared but how and where in cygnus' environment ???? The .DEF file ???
