gdb and multiple sources

melinda_sayang · 04-03-2004, 09:35 PM

Before yesterday, I always debug for one sources using gdb. It is easy. But I try to make program using gtkmm library and glade. Because of that, I got a lot of sources. My question is:

How can you debug in this case?

If I say gdb the_binary_that_I_want_to_debug: it will go to the main file which is just like this simple:

Code:

int main(int argc, char **argv)
{
                                                                                
   Gtk::Main m(&argc, &argv);
                                                                                
   window1 *window1 = new class window1();
   m.run(*window1); 
   delete window1;
   return 0;
}

What I want to watch is this function:

Code:

void window1::on_file_clicked()
{  
	const int mp3 = 1, ogg = 2, no = 0;
	Glib::ustring song = input->get_text(), outputsong( song, 0, song.length()-4 );
	Glib::ustring s1( song, song.length()-3, 3 );
	int j = 0, i = 0, type;

	//Check whether ogg files or mp3 files
	outputsong = outputsong + ".wav";
	if(s1=="mp3") {
		type = mp3;
	}
	else if(s1=="ogg") {
		type = ogg;
	}
	else {
		type = no;
	}
        char* in = new char[song.length()+1]; 
        char* out = new char[outputsong.length()+1];
	char* arg_list[10];

        switch(type) {
		case mp3: strcpy(arg_list[0],"mpg321");
			  strcpy(arg_list[1],in);
			  strcpy(arg_list[2],"-w");
			  strcpy(arg_list[3],out);
			  arg_list[4] = NULL;
			  spawn("mpg321", arg_list);
			  strcpy(arg_list[0],"oggenc");
			  strcpy(arg_list[1],outputsong.c_str());
			  arg_list[2] = NULL;
			  spawn("oggenc", arg_list);
			  strcpy(arg_list[0],"rm");
			  strcpy(arg_list[1],outputsong.c_str());
			  spawn("rm", arg_list);
			  break;
	        case ogg: strcpy(arg_list[0],"oggdec");
			  strcpy(arg_list[1],in);
                          arg_list[2] = NULL;
			  spawn("oggdec", arg_list);
			  strcpy(arg_list[0],"lame");
			  strcpy(arg_list[1],outputsong.c_str());
			  spawn("lame", arg_list);
			  strcpy(arg_list[0],"rm");
			  strcpy(arg_list[1],outputsong.c_str());
			  spawn("rm", arg_list);
			  break;
		default: 
			  break;
	}
}

That function is in window1.cc file. Ok, in main file, I put the breakpoint in this statement

Code:

 m.run(*window1);

After stop in that statement, I try to step but I got this error/warning:
Gtk::Main::run(Gtk::Window&) (window=@0x807d4d0) at main.cc:422
422 main.cc: No such file or directory.
in main.cc

Step again, got this error:
Gtk::Widget::show() (this=0x807d4d0) at widget.h:312
312 widget.h: No such file or directory.
in widget.h

And the error goes on.......

Help me, Guru and buddy!!!!!
