debug problem systemc

[yosri ben salah]

Hi all , 

pls who can expain to me the reson of this warning even my code is too simple 

 warning C4407: cast impossible between different representation of pointer , lthe complier may generate a wrong code

#ifndef ALARM_H_
#define ALARM_H_

#include <systemc>
#include <iostream>

SC_MODULE(Alarm)
{
  sc_core::sc_in<bool> i;

  SC_CTOR(Alarm) :
    i("i")
  {
    SC_METHOD(AlarmMethod);
    sensitive << i.pos();
    dont_initialize();
  }

  void AlarmMethod();
}; // Alarm

#endif // ALARM_H_
----------------------------------------------------------

#include "alarm.h"

void Alarm::AlarmMethod() {
  bool temp = i.read();
   std::cout << sc_core::sc_time_stamp()  <<std::boolalpha << " i: "  << temp << std::endl;
}
------------

#include "detect.h"
void Detect::DetectThread() {
  // Open CV setup
  // required only once.
  while(1) {
    // Call OpenCV motion detection
    // Compare with threshold
    // if greater then write true
    // else
    // false    
    if (!s) 
    {
      s = true;
    } 
    else
    {
      s = false;
    }
    std::cout <<sc_core::sc_time_stamp() << std::boolalpha << " s: "  << s << std::endl;
    o.write(s);
    wait(50, sc_core::SC_MS);
    }
}
------------------------------------------------

#include "top.h"

int sc_main(int argc, char **argv) {
  Top t("t");

  sc_core::sc_start(1000, sc_core::SC_MS);
  sc_core::sc_stop();
  return 0;
}

detect.h source code is not included, so I can't compile this.

Class Top is not declared/defined

[yosri ben salah]

yes you are right , i edited my response Roman

[Roman Popov]

Compiles without any warnings in G++4.8.

[yosri ben salah]

the problem that it also compiles in my visual studio environnement for a week, but now when i tried to debug it runs warning, and memory exception when debuguing 

[yosri ben salah]

 

[Roman Popov]

Runs without any issues on Linux:

0 s s: true
0 s i: true
50 ms s: false
...
950 ms s: false

Unfortunately I have no Windows machine near me to check with MSVC.

[yosri ben salah]

thank you for your support Roman. it possible that the warning due to systemC configuration in MSVC. i will try to fix it but pls when you have windows machine try to compile it thank you Roman

The error message is an indication, that you might miss the /vmg switch in your the MSVC project.

Quoting from the SystemC INSTALL file (emphasis mine):

Creating SystemC Applications
-----------------------------

1. Start Visual Studio. From the Start Page select New Project and Win32
   Console Project. Type the project name and select a suitable location
   then click OK.

2. Select the Application Settings page of the Win32 Application Wizard
   and make sure the 'Empty project' box is ticked. Click 'Finish' to
   complete the wizard.

3. Add new/existing C++ files to the project and edit code.

4. Display the project Property Pages by selecting 'Properties...' from
   the Project menu.

5. From the C/C++ tab, select the Language properties and set
   'Enable Run-Time Type Info' to Yes

6. From the C/C++ tab, select the Command Line properties and add /vmg
   to the 'Additional Options:' box.

7. From the Linker tab, select the Input properties and type 'systemc.lib'
   in the 'Additional Dependencies' box.

8. Click OK

Hope that helps,
