简单的makefile.为什么.exe被创建，然后被make删除

我还有另一个问题，netbeans不创建。exe，但netbeans没有错误输出。这个问题仍然没有解决。因为我被要求在没有IDE的情况下编译这个项目，而我以前从来没有做过，所以我创建了这个简单的程序来学习makefiles。

//main.cpp
int main() { 
  int i = 1;
  return 0;
}

我的makefile看起来像这样:

project000: main.o
    g++ -Wall main.o -o project000
main.o: main.cpp
    g++ -Wall -c main.cpp
clean:
    rm *.o project000

当我进入项目目录并执行'make'时，.o文件被创建，我可以看到project000.exe被创建然后删除!因此，我通过将makefile缩短为

project000: main.o
    g++ -Wall main.o -o project000
main.o: main.cpp
    g++ -Wall -c main.cpp

但是同样的事情发生了。正在创建并删除。exe文件。

有人知道吗?

'make -d'的输出(可能不包括开头，因为我运行它时提示符的行数太少)
