(1) About the experimental environment
< p> Open the terminal
After is opened, it looks like this
Check the instructions given by the teacher, the instruction file is README.md
see the specific content for yourself .
(2) specific operations
①View and modify the code
software understand
cd enter/ moocos/ucore_lab/labcodes/lab1 is behind this directory
you can use understand to view< /p>
Just enter understand directly
understand cracking:
However, this understanding cannot be used. You need to purchase the product or enter the license
Don’t worry, the license is ready for you here
I forgot to take the screenshot, respectfully Please understand.
Select Enter License Code
select again Add Eval or SDL
then enter 19878CBBFB13
the mailbox can be omitted, click OK
②Compiled code
The same is cd After entering the directory /moocos/ucore_lab/labcodes/lab1,
Enter make,
[~/moocos/ucore_lab/labcodes_answer]
moocos-> cd lab1_result
[~/moocos/ucore_lab/labcodes_answer /lab1_result]
moocos-> make

Enter make ｑEBMU
In hardware simulation Run the program in the environment
③Check and score
In this integrated environment, there is an evaluation function
input: make grade
At this point, you should have a general understanding of the operating system experiment. & Understand some basic operations of Linux.
The operating system class has entered the experimental stage, and I was confused when I first pondered it , Took a lot of detours. I spent a lot of time trying to set up the experimental environment by myself, but failed. However, trying to use the experimental environment given by the teacher is very smooth, and I hope it can help students who see my blog. Welcome everyone to leave a message in the comment area!
