Error : names the constructor, not the type. while compiling with g++4.6.1

I am compiling the code with g++4.6.1 on aix6.1 and getting this error:-

ViaChecks.h:14:3: error: 'BuPolygonEX<AllPass<CornerT<NetAndVal<ZVal3> > > >::IOPS::Base {aka BuPolygonCore<bu_polygon_clean_func, no_derivatives, AllPass<CornerT<NetAndVal<ZVal3> > > >::IOPS}::IOPS' names the constructor, not the type

The structure is defined as :

struct ViaSquareCheck : BuPolygonEX<AllPass<CornerT<NetAndVal<ZVal3> > > > {
  typedef BuPolygonEX<AllPass<CornerT<NetAndVal<ZVal3> > > > Base;
  DEFINE_ENGINE_PROPERTIES_INHERIT(Base::IOPS, void update() { Base::update(); i().xregion_1nm_oversize(x0nm); o().xregion_1nm_oversize(x0nm); o().derivatives(x_dom); o().bu_polygonized(yes); }); // via_square_dim property is added inside
  membert(int, amount, -1, ViaSquareCheck);
  ViaSquareCheck();
  ViaSquareCheck* output(DFC* dfc) { return set_output(0,dfc); } // single output returns good vias
  ViaSquareCheck* set_output(int k, DFC* dfc);
  void option(const string& pname, const string& pval); // some options change engine properties
private:
  BadViaMultiplexer<C>* mux;
  GIM2a<APC> bad_via_gim;
  GIM2a<APC> good_via_gim;
  member(bool, linked, false);
  member(bool, ok_45, false);
  void link();
  member(ViaSquareCheckNetProcess*, np,NULL);
};

Definition of DEFINE_ENGINE_PROPERTIES_INHERIT:-

#define DEFINE_ENGINE_PROPERTIES_INHERIT(SSSS, extras...) \
struct IOPS : SSSS { \
      EnginePropertiesVector& i() { return SSSS::i(); }; \
      EnginePropertiesVector& o() { return SSSS::o(); }; \
      EngineProperties& i(int n) { return SSSS::i(n); }; \
      EngineProperties& o(int n) { return SSSS::o(n); }; \
      typedef SSSS Base; \
      extras; } ep_;

Thanks.

It is a qualified name like Base::IOPS, we need to have a typename before that. You need to pass a type instead of qualified name Base::IOPS, so i defined a type 

typedef Base::IOPS MYIOP

and then passed that type, so the error "this is not a type" is gone.

I'd say that when you say:

DEFINE_ENGINE_PROPERTIES_INHERIT(Base::IOPS, ...

You should write:

DEFINE_ENGINE_PROPERTIES_INHERIT(Base, ...

That is, without the ::IOPS.

This diagnostic is given if you use the name 

myclass::myclass

This name does not denote the class myclass but its constructor(s)

You should preprocess your source code with something like

g++ -C -E yoursource.cc | grep -v '^#' > yoursource.ii

(the grep -v removes the line numbering)

then compile the preprocessed form with

g++ -Wall -c yoursource.ii

then look at the locations of the error message in yoursource.ii

You might also ask on [email protected].

But as others pointed out, your code is not very pretty...
