Building with Clang version 4

Some phones need clang to build the kernel instead of gcc

Follow the instructions in README_kernel.txt
Download the correct toolchain
Here are a few examples

Note:
For Mediatek you will need to apply the strcpy patch
https://github.com/physwizz/a22/commit/5b705dfa2e98961d3b72b0ba32ac77884e9a42e0

Build Method #1 Clang

You will need 3 toolchains
1. Cross-compile (gcc)
https://github.com/physwizz/toolchain_cross-compile
Or
https://github.com/physwizz/compiler

I put it here
/home/<user>/gcc

2. Clang
https://github.com/physwizz/toolchain_clang
Or
https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+archive/android-10.0.0_r3/clang-r353983c.tar.gz

I put it here
/home/<user>/clang

3. Clang-triple
https://github.com/physwizz/toolchain_clang-triple
Or
https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz

I put it here.
/home/<user>/gcc-linaro



Edit Makefile with these

CROSS_COMPILE=/home/<user>/gcc/bin/aarch64-linux-android-

CC=/home/<user>/clang/bin/clang

CLANG_TRIPLE=
/home/<user>/gcc-linaro/aarch64-linux-gnu-

To build I used these commands

$ make clean && make mrproper
$ export ANDROID_MAJOR_VERSION=q
$ export ARCH=arm64
$ make -C $(pwd) O=$(pwd)/out KCFLAGS=-w CONFIG_SECTION_MISMATCH_WARN_ONLY=y <your-device_defconfig
$ make -C $(pwd) O=$(pwd)/out KCFLAGS=-w CONFIG_SECTION_MISMATCH_WARN_ONLY=y

Output can be found in
home/<user>/out

Build Method #2 Proton-Clang

Download Proton-Clang
https://github.com/physwizz/Toolchains-for-Eureka

I put it here.
/home/<user>/toolchains/proton-clang

Don't edit Makefile

Add proton-clang to your path

export PATH="$HOME/toolchains/proton-clang/bin:$PATH"

Build with
$ make clean && make mrproper
$ export ANDROID_MAJOR_VERSION=r
$ export ARCH=arm64
$ export CC=clang
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make -C $(pwd) O=$(pwd)/out KCFLAGS=-w CONFIG_SECTION_MISMATCH_WARN_ONLY=y <your-device>_defconfig
$ make -C $(pwd) O=$(pwd)/out KCFLAGS=-w CONFIG_SECTION_MISMATCH_WARN_ONLY=y


Output can be found in
home/<user>/out

If you get a python error
Change "python" to "python3" in Makefile

Mediatek
Patch for strcpy error

git remote add a125 git@github.com:physwizz/A125M.git
git fetch --all
git cherry-pick 3aea117fb57d4eba3e592cc953054b98256a31c6
git push origin main -f

Tester @krithik

-OneUI or GSI
-Most securities disabled
-CPU Governors: conservative, ondemand, userspace, powersave, interactive, performance.
-Interactive is default governor
-SE linux enforcing
-CPU overclocked and underclocked
-Big: 312 - 2080
-Little: 208 - 1690
-GPU: 343 - 1300
-Extended battery life
-doesn't need Magisk

But if you use magisk
Works with 19.3 - 21.4
DON'T USE HIDE WITH MAGISK 22

Install from magisk modules
Use rootexplorer to access
/data/local/AIK-MOBILE
Add boot.img or recovery.img and tap unpackimg.sh
Exit the folder and return to see the files.
Edit the files (eg to add a new Image rename Image to boot.img-zImage and insert in split-image folder)
