Classwork 18

Logistics

  • Due: Monday, April 3rd AoE.
  • Submission instructions: make sure that the required files (lab3.c, lab3.h,print.c., read.c, Makefile) are in your /classwork/week11/mon/ directory.
  • Deadline reminder: after the deadline passes, you cannot earn any points for this assignment.

Learning outcomes

  • Practice writing Makefiles

Assignment

  • Log in to the server.
  • From your home directory, navigate to classwork/week11/mon/, creating directories week11 and mon if necessary.
  • Copy lab3.c, lab3.h, print.c, and read.c from /public/classwork/week11/mon/, or take the solution file from /public/labs/lab3/ and split it into those four files.
  • Write a makefile in a file called Makefile that builds the executable lab3. It should have four rules: one to link the three object files, and one to compile the object file for each C file. If you would like, you can copy /public/classwork/week11/mon/Makefile to get you started.
  • Remember that Lab 3 takes in an input file via redirection. To test your executable, you will need to run
    ./lab3 < /public/labs/lab3/testdata.txt

Autograder

You can run the autograder yourself by running

/public/classwork/week11/mon/autograder.sh

The autograder.txt file will be created or replaced. You may get a few lines of output about not being able to remove files, etc. This is okay.

You can see the output that make got when it was run by the autograder in tmp_make_output.txt. Looking at this may help if you are not getting full credit due to a make issue.

Grading turnaround

The autograder will be run at 6am to calculate final scores. Scores will be uploaded to D2L by the next class period.
