Post subject:  how to initialize const?
code:

Event.h
        Event(string des, string loc, Date s, Date e);
        string description;
        string location;

        const Date start; //<-
        const Date end; //<-


code:

Event.cc

Event::Event(string des, string loc, Date s, Date e):start(s),end(e)
{       description= des;
        location = loc;
}


everything works up to here... like when i compile, it doesnt scream at me

but in another class, where i use this class

code:

//Calendar.cc

        const Date tsd(sd);
        const Date ted(ed);
        Event tempEvent(des,loc,tsd,ted);

then i got this compile error

Calendar.cc:43: instantiated from here
/fsys/.software/arch/gcc-3.4.2/bin/../lib/gcc/sparc-sun-solaris2.8/3.4.2/../../../../include/c++/3.4.2/bits/vector.tcc:238: error: non-static const member `const Date Event::start', can't use default assignment operator
