So I passed it into IMPLIB tool to have the corresponding .LIB file, but I always have a link error. The only solution I found is to pass by the converting tool given by Builder and to export the makefile. In this way, the generated DLL is always compatible, but project integrity is hard to keep safe : For each modification, you must : - export the makefile, - test the compatibility with the other project. Does anyone know how to have only one project (Visual or Builder) and how keeping the resulting DLL compatible for Visual project ? Is there project option to avoid ? Thanks.
