No, it doesn't. I also compile another one with originial configs (meaning having no edits) but still it doesn't as well.
Also can you explain why using "make" will finish compiling but using "make -j64" (from build_kernel.sh) will make my pc laggy, skip many errors and not finish the process? Also my device doesn't support TWRP, so I have to flash kernel via kernel manager apps Yeah i do know that but it didn't work. I think the problem lies in the image itself. I just don't know what the problem is Shame using the newest versions of gcc has the notifications of gcc deprecation so I don't like it (though I know how to suppress them) you can ignore those messages

I encounter these errors. I switch to python 3 and edit python = python 3.8 in makefile. Should I switch to python 2 as with gcc, the same thing happens and I have to switch back to python 2

This is a first attempt.
It's not overclocked so don't expect anything miraculous.
Thanks to @Chatur27 for building help and @Topser99 for the flashable zip
THIS IS WHAT I DID
Requirements
Use Linux 64bit ( I used Linux Mint Mate in a Virtual Box)
Linux setup
$ sudo apt update
$ sudo apt upgrade
$ sudo apt-get install git-all
$ git config --global user.name "physwizz"
$ git config --global user.email " [email protected] "
Kernel setup
1. Download the compiler
Unzip into "Compiler" folder
2. Download the Source Code ( https://opensource.samsung.com/main )
Search for A205 and select QQ version (Latin)
Extract the kernel.tar.7z
extract into "Kernel" folder
Beginners guide to github
I have always had a lot of difficulty with github.
I have jotted down a few things which might help some new kernel builders.
A. Github Setup
1. Go to github and Open a new Repo
I called mine "physwizz_kernel"
2. To set up SSH key
$ git config --global user.email " [email protected] "
$ git config --global user.name "Your Github Name"
$ ssh-keygen -t rsa -b 4096 -C " [email protected] "
Press enter 3 times
$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/id_rsa
$ sudo apt-get install xclip
$ xclip -sel clip < ~/.ssh/id_rsa.pub
3. The SSH key will be in clipboard
Go to github settings => SSH and GPG keys
Paste key here
B. Using github
1. Open Terminal In The Kernel Folder
$ git init
$ git remote add origin (github id) mine is [email protected] : physwizz/physwizz_kernel.git
$ touch README
$ git add README
$ git add --all
$ git commit -m "Initial commit"
$ git push -u origin main
2. To cherry pick a commit from another github repository
firstly add the other repository to your kernel
$ git remote add other https:<other address>
$ git fetch --all
$ git cherry-pick [hash_id]
3. to push changes to github
$ make clean && make mrproper
$ git add --all
if the change is your own
$ sudo git commit -a
write comment
ctrl o (to output)
enter
ctrl x (to exit)
$ git push origin main
if the change is a cherry pick
$ git commit "change made" --author="Author's name<author's email>"
$ git push origin main
4. If it doesn't work or if you want to try something else
$ git revert <commit hash code>
$ git push origin main
$ git reset --hard < last clean commit hash >
$ git push origin main -f
$ git cherry pick <clean commits >
$ git push origin main
5. to edit last commit
$ git commit --amend -e
$ git push origin main
Please give any feedback.

Kernel Building
1. open the defconfig file with text editor
Mine was located at
/home/physwizz/Kernel/arch/arm64/configs/exynos7885-a20_defconfig
You can make a copy of this file and call it original_defconfig
CHANGES I MADE
physwizz_kernel_V1
CONFIG_LOCALVERSION="physwizz"
# CONFIG_CC_STACKPROTECTOR_STRONG is not set
Later versions in post #2
2. open terminal
cd Kernel
make clean && make mrproper
export CROSS_COMPILE=/home/physwizz/compiler/bin/aarch64-linux-android-
export ARCH=arm64
export ANDROID_MAJOR_VERSION=q
make exynos7885-a20_defconfig
3. Output is found in /home/physwizz/Kernel/arch/arm64/boot
4. Copy Image from boot folder and Insert it into the MyKernel.zip
5. Extract Version and edit it then reinsert
To use Anykernel to make your own zip
Extract MyKernel.7z to a folder, copy kernel image there, open terminal in that folder and type:
zip -r9 UPDATE-AnyKernel3.zip * -x .git README.md *placeholder
TheUPDATE-AnyKernel3.zip will be in the folder.
Cut and paste it outside the folder then flash it from TWRP.
Make sure you don't leave the UPDATE-AnyKernel3.zip in the MyKernel folder because it will interfere with the next zip you make.
Need to flash Magisk 20.4 or Magisk 21
Works with stock dtbo or Eureka dbto
If you flash Eureka dbto you will get overclocking of the GPU.
Overclocking
Version 1.4 is when I started overclocking
