How to Compile & Execute

Requirements

• Compiler: gcc -std=c99 nameOfFile -o whatYouWantTheExecutableToBeNamed
• Dependencies: None needed to be downloaded

Compilation

make

This will build the modules you need to run the part 2 and part 3 program. However, you need to execute this command in both directories because they have different makefiles.

Execution

sudo insmod your_module.ko
execute your command here
sudo rmmod your_module.ko

For part 2, run this for a basic demonstration:

cat /proc/elevator

For part 3, run this for the full elevator:

watch -n 1 cat /proc/elevator

• Then, pull up a new terminal, go to the producer-consumer executables, and execute these commands:

./producer urNumOfStudents
./consumer --start
./consumer --stop
