Hello,
My name is Keanu Melo (ID: knm95) and I am a student from Section 5.
I am working on Project 2 on a Windows device and encountering an error
whenever I type "make" in the Ubuntu WSL terminal. This error is similar to
the one I had during Project 1, and by that time the professor was the
person who helped me resolve the issue.
The error I am receiving is "[Makefile:51: main] Error 1"; although, at the
bottom of the email I will leave the entire output that comes from the
terminal in case that is more helpful.
I would appreciate any help regarding this issue.
Best,
Keanu Melo
