С чего начать писать прогу? 0

С чего начать писать прогу на C++ в KDevelop? На C все как по маслу было, а на C++ — самую простейшую прогу скомпилить не могу :(

#include

#include «onewidget.h»

oneWidget::oneWidget(QWidget* parent, const char* name, WFlags fl)

: oneWidgetBase(parent,name,fl)

{}

oneWidget::~oneWidget()

{}

/*$SPECIALIZATION$*/

void oneWidget::button_clicked()

{

if ( label->text().isEmpty() )

{

label->setText( «Hello World!» );

}

else

{

label->clear();

}

}

#include «onewidget.moc»

соответственно что он мне пишет:

den@studio src]$ cc onewidget.cpp
