Go to terminal and type:

$ make

This will create linker.exe, then you can test inputs:

$ ./linker "input-file"

The folder lab1samples also has scripts to check all the sample inputs. To test them:

Create yourself a directory where your outputs will be created.

$ cd lab1samples

$ ./runit.sh "your-outdir" "path-to-linker.exe"

$ ./gradeit.sh "." "your-outdir"
