error: ‘process’ is not a member of ‘host_cntrl::SC_CURRENT_USER_MODULE’

[mohitnegi]

hello all ,

 

Getting this error while compiling my system C moduole ...

Could anyone explain me what this is ??

[Philipp A Hartmann]

You don't have a member function called 'process' in your 'host_cntrl' class?

Hard to tell without actual code.

Or you are *not* using SC_CTOR, you've declared an SC_THREAD, and you've forgotten SC_HAS_PROCESS ?

P.S. As Philipp says, the code would help :-)

Thanks for the response guys ...

host_cntrl.hpp

#ifndef HOST_CNTRL_H
#define HOST_CNTRL_H
#include "systemc.h"

class host_cntrl : public sc_module
{
  public:
  SC_CTOR(host_cntrl) {
  SC_THREAD(process);
  }
  //SC_HAS_PROCESS(host_cntrl);
  
  private 
 ......

 }
 

then in host_cntrl.cpp

#include "host_cntrl.hpp"

void host_cntrl::process()
{
  while(1)
  {
  wait(e_HCE);//Host COntroller is enabled by SW
  cout <<"hello"<<endl;
  }
}

Make sure that you have the "process" function declaration in  the body of host_cntrl:

class host_cntrl : public sc_module
{
public:
// SC_CTOR(), etc.
private: 
  void process();
};

thanks that problem is solved ....

now i am using this

bool HCE_register::behavior_after_write(uint32_t data){
       sc_event e_HCE;
       if(data==0x01)
         return e_HCE.notify();
       else
         return 0;
 }

and in other code as mentioned above host_cntrl.cpp  i am using it ...

 

But am getting this compilation error ..

home/mic-24/Desktop/dmi/ufs_dmi/ufs/src/ufs_registers.cpp: In member function ‘bool HCE_register::behavior_after_write(uint32_t)’:
/home/mic-24/Desktop/dmi/ufs_dmi/ufs/src/ufs_registers.cpp:614: error: void value not ignored as it ought to be

could you explain me this errror here ???

[Philipp A Hartmann]

bool HCE_register::behavior_after_write(uint32_t data){
       sc_event e_HCE;          // <-- strange
       if(data==0x01)
         return e_HCE.notify(); // <-- error
       else
         return 0;
 }

 

The error is caused by the fact that the notify() function of sc_event returns nothing (i.e. 'void').

So you can't return the (non-existing) return value in the marked line above.

 

Secondly, e_HCE is a local variable.  You won't be able to trigger any other process by notifying this event.  This looks wrong as well.
