Hi Jozsef,

Ah, I see. Yes, I somehow missed this. Now it works.

Thanks for your help!

Best,
Jonah

Hi Jonah,

Did you make sure all template specializations used in your code are listed in the .ci file, such as

message ValueMsg< int >;

and that the header file has the CK_TEMPLATES_ONLY define, such as

#define CK_TEMPLATES_ONLY

#include "msg.def.h"

#undef CK_TEMPLATES_ONLY

in the bottom?

Hello everyone,

I would like to template a new message type by a variable type so that I can treat it as a generic variable container. However, I'm having a bit of trouble. The following code is in my module file:

template<typename value_t> message ValueMsg;

and the commensurate implementation is:

template<typename value_t>
class ValueMsg : public CMessage_ValueMsg<value_t> {
public:
  value_t value;
  ValueMsg() { }
  ValueMsg(value_t v) {
    value = v;
  }
};

In the linking stage of compilation, I get a bunch of errors of the following type:

In function `CMessage_ValueMsg<int>::operator delete(void*)':
/home/jmiller/programming/charmploration/fibonacci-futures/fib.decl.h:105: undefined reference to `CMessage_ValueMsg<int>::dealloc(void*)'
/home/jmiller/programming/charmploration/fibonacci-futures/fib.cpp:53: undefined reference to `CMessage_ValueMsg<int>::operator new(unsigned long, int)'

Is there something I'm doing wrong? Or is templating messages simply not possible?

Alternatively, is it possible to use the PUP framework to define the serialization for a message, if I want to, for example use futures?

Thanks in advance for your help!

Best,
Jonah Miller
