Sorter.cpp

#include <string>
#include <vector>
#include <fstream>
#include <iostream>
#include <sstream>

using namespace std;

class webpage {

	public:
	std::string url;
	int count;
	webpage( std::string url, int count );

};

webpage::webpage( string url_, int count_ ) {
	url = url_;
	count = count_;
}

int main() {
	return 0;
}

So sieht mein makefile aus:

CFLAGS = -m64 -g -Wall -Werror -Wcomment
LDFLAGS = -m64 -Wall -Werror -Wcomment

all: Sorter

Sorter.o : Sorter.cpp Sorter.h
g++ ${CFLAGS} -o Sorter.o -c Sorter.cpp

Sorter: Sorter.o
gcc ${LDFLAGS} -o Sorter Sorter.o

clean:
rm -f *.o
rm -f Sorter

und ich erhalte folgende Fehlermeldung:

Was geht hier ab? Ich verstehe den Compiler nicht.

gcc ${LDFLAGS} -o Sorter Sorter.o

Mein gcc-fu ist etwas eingerostet, aber müsste dort nicht g++ statt gcc stehen?
