umm..

Guess I'm confused about something here.

I try:

class test {
public:
test() { }
virtual ~test() = 0 { };
};

and get from compiler:

//sc blah.cpp -Ae -mn -C -WA -S -NL -3 -a8 -c -gf -D_MT=1
-D_STLP_NO_NEW_IOSTREAMS=1 -oblah.obj
//Error: D:\APPS\DM\APPLIANCE\blah.h(60): ';' expected following declaration of
struct member

If I remove pure virtual constraint, or move definition out of class, all is well. Am I missing something about the rules of virtual d'tor definition in classes?

An initial reaction is to question whether it is the trailing semi-colon

Sorry. Adding the ";" was a knee jerk reaction when compiler gave error. I accidently posted posted that. Compiler responds the same with or without trailing ";".

See 10.4 Abstract classes of the C++ Standard:

(2) ... [Note: a function declaration cannot provide both a pure-specifier
and a definition -end note] [Example:
  struct C {
    virtual void f() { }=0;     // ill-formed
  };
-end example]

Thanks Christof. Is there an online reference to the C++ standard?

WOW. Thanks so very much.
