I am using visual c++ version 6, I have compiled the systemC library, then creates a new project contains multiple files then I try to build it but the building failed due to an error called "error C2679" and this the error message:
"d:\systemc-libraries\systemc-2.0\systemc-2.0\src\systemc\communication\sc_signal.h(234) : error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'const struct packet_type' (or there is no acceptable conversion)"
and this the code in which the error occured:-
