Hi

I am trying to link the mars.d program which come with Dparser and i get the following errors.

../dparser/dparser.dmd.Aggregate.o: In function `_D7dparser3dmd9Aggregate11accessCheckFS7dparser3dmd4Root3LocC7dparser3dmd5Scope5ScopeC7dparser3dmd10Expression10ExpressionC7dparser3dmd11Declaration11DeclarationZv':

collect2: ld returned 1 exit status

Does anybody know what the problem is ??

The last error seems to referrer to the following function can anyone spot the error ??

	static void multiplyDefined(Loc loc, DSymbol s1, DSymbol s2)
	{
	    //printf("s1 = '%s'\n", s1.toChars());
	    //printf("s2 = '%s', parent = %p\n", s2.toChars(), s2.parent);
	//	#if 1
	    s1.error( "conflicts with %s at %s", s2.toPrettyChars(), s2.locToChars() );
        if (loc.filename)
        {
            .errorLoc(loc, "%s at %s conflicts with %s at %s", s1.toPrettyChars(), s1.locToChars(), s2.toPrettyChars(), s2.locToChars());
        }
        else
        {
	        s1.errorLoc(loc, "conflicts with %s at %s", s2.toPrettyChars(), s2.locToChars());
        }
	}

That's the TypeInfo for a tuple(char[],char[],char[],char[],char[]), probably from:

>             .errorLoc(loc, "%s at %s conflicts with %s at %s", s1.toPrettyChars(), s1.locToChars(), s2.toPrettyChars(), s2.locToChars());

Is that function by any chance declared as something like "void errorLoc(Loc, ...)"?
(IIRC TypeInfo for tuples is used to pass varargs, and this is the only function call with >= 5 parameters)

As to why that TypeInfo doesn't get emitted, that may be a long story.
What is your compiler command line? (including compiler please)
Do you use -c to compile files one-by-one and then link or do you just pass all files at the same time? Whichever it is, does this error disappear if you switch?

Yes, it is defined like
// print an error message for a location void errorLoc( Loc loc, ... )
{
    if( !global.gag )
    {
		doError(loc, _arguments, _argptr);
    }
}
