Ofstream / ifstream

[Kollode]

HI,

ich habe folhendes Programm Geschrieben:

#include <iostream>
#include <string>
#include <fstream>
using namespace std;

int main()
{
        string ip;			//Hier wird die IP gespeichert
        string host[30];	//Hier wird der Inhalt der /etc/hosts Date gespeichert
        string gesamt;
        string iploc="/root/ip/ip.txt";  //Pfad zur Datei mit der IP
        string hostloc="/etc/hosts";	//Pfad zu Hosts Datei

//-----------------------------------------------

        ifstream ausgabe(iploc.c_str(),ios::in); //Öffnet die ip.txt
        getline(ausgabe,ip);					 //Liest die erste Zeile aus ip.txt ein
        ip.erase( 0, 24 );						 //Löscht die Zeichen vor der IP
        int loc = ip.find(")",0);                //und
        ip.erase(loc,100);						 //nach der IP

        ausgabe.close();						 //Schliesst die Datei wieder

//-----------------------------------------------

       ifstream aus_host(hostloc.c_str(),ios::in);

        for(int i=0;i!=30;i++)
        {
               getline(aus_host,host[i]);
        }

        aus_host.close();

//-----------------------------------------------

        int loc_host = host[9].find("loc",0);
        host[9].erase( 0, loc_host-1 );
        gesamt=ip + " localhost server";
        host[9].replace( 0, 30,gesamt);

//-----------------------------------------------

        ofstream ein_host(hostloc);
        ein_host.seekp(ios::beg);

        for(int i=0;i!=30;i++)
        {
                ein_host<<host[i]<<endl;
        }

        ein_host.close();

}

Nur wenn ich es dann mit gcc auf meinem Linuxrechner kompiliere spuckt der folgende meldung aus:

ip.cpp: In function int main()': ip.cpp:45: error: no matching function for call tostd::basic_ofstream<char,
std::char_traits<char> >::basic_ofstream(std::string&)'
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/include/g++-v3/iosfwd:92: error: candidates

ich habe schon rumprobiert aber es wird höchstens schlimmer.
Kann vielleicht mal einer von euch kucken oder er den Fehler findet?

Hi,

ändere Zeile 45 mal wie folgt:

ofstream ein_host(hostloc.c_str());

[Kollode]

Hatte ich auch schon macht es in meinen Augen nur noch schlimmer.

Das kommt dabei raus.

Also bei mir wird dein geposteter Quelltext (mit der besagten Änderzung von CarstenJ) fehlerfrei compiliert. (Compiliert mit g++.exe und Borland C++ 5.0.x)
Welchen Compiler verwendest du denn?

Caipi

[Kollode]

Vergisst am besten das ich hier war...

Als ich Caipi´s antwort gelesen habe wurde mir klar wodran es lag ...
Ich habe auf dem Linux system immer gcc statt g++ ausgeführt ....

schande über mich ..
