Charm++ parallel programming system

[Lawrence Kidder <kidder AT astro.cornell.edu>]

Hello,

I am using templates in a Charm++ code and have encountered

Charmxi syntax error> syntax error
Invalid entry method attribute list

when compiling an interface file.

The problem is illustrated by the following simple example:

I have Typename.C containing:

#include "Typename.decl.h"

template <typename T>
class A : public CBase_A {
public:
  A() {}
  void help(const typename T::X& arg) {}
};

class B {};

class C { typedef B X; };

class Main : public CBase_Main {
public:
  Main(CkArgMsg* m) {}
};

#include "Typename.def.h"


and Typename.ci containing:

mainmodule Typename {
  template <typename T>
  array [1D] A {
    entry A();
    entry void help(const typename T::X&);
  };

  array [1D] A<T>;

  mainchare Main {
    entry Main(CkArgMsg* m);
  };
};



The syntax error is caused by the keyword typename in the entry method 
A<T>::help

If I remove the keyword template, the interface file will compile, but 
of course Typename.C no longer compiles because the generated Charm++ 
methods fail with error: missing 'typename' prior to dependent type name 
'T::X'

Is there a special syntax I should be using in the interface file to get 
this to compile properly?

Thanks,
Larry
