Привет, уважаемые гуру!! Проблема такая. Очень нужно написать на Qt3.3 http-сервер. Благо есть пример под названием httpd, поставляемый с QT. Компилирую. Запускаю. Набираю в бразуере 127.0.0.1 и он падает. Код не изменял. компилирую, как есть. Дебагил - ничего хорошего это не дало. СПАСИБО за помощь!! Вот его код:
#include <stdlib.h>
#include <qsocket.h>
#include <qregexp.h>
#include <qserversocket.h>
#include <qapplication.h>
#include <qmainwindow.h>
#include <qtextstream.h>
#include <qvbox.h>
#include <qlabel.h>
#include <qtextview.h>
#include <qpushbutton.h>

{
if ( !ok() ) {
qWarning("Failed to bind to port 8080");
exit( 1 );
}
}
void newConnection( int socket )
{
// When a new client connects, the server constructs a QSocket and all
// communication with the client is done over this QSocket. QSocket
// works asynchronouslyl, this means that all the communication is done
// in the two slots readClient() and discardClient().
QSocket* s = new QSocket( this );
connect( s, SIGNAL(readyRead()), this, SLOT(readClient()) );
connect( s, SIGNAL(delayedCloseFinished()), this, SLOT(discardClient()) );
s->setSocket( socket );
emit newConnect();
}

// This slot is called when the client sent data to the server. The
// server looks if it was a get request and sends a very simple HTML
// document back.
QSocket* socket = (QSocket*)sender();
if ( socket->canReadLine() ) {
QStringList tokens = QStringList::split( QRegExp("[ \r\n][ \r\n]*"), socket->readLine() );
if ( tokens[0] == "GET" ) {
QTextStream os( socket );
os.setEncoding( QTextStream::UnicodeUTF8 );
os << "HTTP/1.0 200 Ok\r\n"
"Content-Type: text/html; charset=\"utf-8\"\r\n"

}
}
