Operating system kernel compilation

OS compiles the kernel

1. Install the necessary support

sudo apt-get install libncurses5-dev libssl-dev 

sudo apt-get install build-essential openssl 

sudo apt-get install zlibc minizip 

sudo apt-get install libidn11-dev libidn11

2. Enter the terminal to start compiling

Make your terminal into your linux kernel directory by cd,

Next execute the following command:

sudo make mrproper 

sudo make clean 

sudo make menuconfig

At this time, because I am using a virtual machine, there are some problems that dependencies do not exist, as shown in the figure:

Then the solution, according to the error prompt in the figure, sudo apt install <file name> can be solved.

Then execute the command make.

3. Compile the module

Execute the command: sudo make modules

This takes a long time.

4. Install the module and kernel

make modules_install

make install

sudo update-grub2

reboot

5. Problems after reboot

As shown in the figure:

This is because the module is not installed successfully, enter grub2, re-select the kernel to enter the system, and reinstall the module can be solved.
