[OpenSIPStack] Problems with Ptrace

[Claudio M. <cmi...@gm...>]

Hello,

I was working in a softphone and during my work I discovered that my log
file was not being created.
Since I was using Ptrace I found that it was really weird. Actually my
program creates a  log file, but the log sees only the PTRACE's in the main
file. I can not use Ptrace in files that are not my main file.

I tried to put "# define PTRACING 1" in my other files, but it did not work
as well.

The following example does not work :

hello.cpp

#include <iostream>
#include <ptlib.h>
using namespace std;
class Hello
{

  public:
    void digaoi(){
    PTRACE(1,"Inside hello \n");

    cout << "Hello world!\n";
    }

};

oi.cpp - main file


#define PTRACING   1

#include <ptlib.h>
//#include <iostream>

#include "C:\Documents and Settings\voip\My Documents\hello.cpp"


class Oi : public PProcess
{
  PCLASSINFO(Oi, PProcess)
  public:
    void Main();
};

PCREATE_PROCESS(Oi)

void Oi::Main()
{
    Hello * hello = new Hello();

    hello->digaoi();

    char * filename = "C:\\Documents and
Settings\\voip\\Desktop\\ttt\\src\\buda3.txt" ;

    //cout << "Test";

    PTrace::Initialise(32, filename, PTrace::Blocks | PTrace::Timestamp |
PTrace::Thread |PTrace::FileAndLine);

    PTRACE(1,"Inside oi.cpp \n");

}


Do you have any sugestion, or even a clue ?

Thanks in advance.

Hi,

First of all...

You are calling hello->digaoi() before initializing PTrace. Naturally, 
no logging was done in hello.

void Oi::Main()
{
    Hello * hello = new Hello();

    hello->digaoi(); // ********* Move this below...

    char * filename = "C:\\Documents and Settings\\voip\\Desktop\\ttt\\src\\buda3.txt" ;

    //cout << "Test";

    PTrace::Initialise(32, filename, PTrace::Blocks | PTrace::Timestamp | PTrace::Thread |PTrace::FileAndLine);

    PTRACE(1,"Inside oi.cpp \n");
}

Alternatively, you can use this for logging...

** Oi.h

#include <ptlib.h>
#include <Logger.h>

class Oi : public PProcess, public Tools::Logger
{
  PCLASSINFO(Oi, PProcess)
  public:
    void Main();
};

** Oi.cpp

#include "Oi.h"
#include "Hello.h"

PCREATE_PROCESS(Oi)

using namespace Tools;

void Oi::Main()
{
  Hello* hello = new Hello();

  // PTrace::Initialise(32, "C:\\buda3.txt", PTrace::Blocks | 
PTrace::Timestamp | PTrace::Thread | PTrace::FileAndLine);
  PTrace::SetLevel( 3 ); // The level just means print PTRACE(1, ..) to 
PTRACE(3, ..)
  Logger::SetDefaultLogStream( new Tools::LoggingFileStream( 
"C:\\buda3.txt" ) );

  hello->digaoi();

  PTRACE(1, "Inside oi.cpp \n");

  delete hello;
}

Now you should be able get logs from both PTRACE and LOG macros.
