I'v written the Makefile below. I'm getting the following error during compilation. I'm not sure what IBS is? Is it missing the L from LIBS or something?
Follow on question:
This is the directory structure.
.
├── Makefile
└── src
├── include
│ └── utils.h
├── main.c
└── utils.c
However, when I run make, this is the output. It doesn't seem to be picking up and building the file utils.c?
