Makefile看起来不对，以下行

The Makefile looks wrong, the following line

Member 8186541 wrote:

g ++ hw1.cpp -o hw1

g++ hw1.cpp -o hw1

应该(可能)是；

should (probably) be;

g++ -c hw1.cpp -o hw1.o

您应该以其他方式修复其他编译指令，并最终添加链接指令.

You should fix, in similar way the other compiling directives and eventually add the linking one.
