Samsung S20 FE kernel

[privacyguy123]

bro can you link the files needed to compile this kernel? can't get it to work with your files/video

################################################################################
1. How to Build
        - get Toolchain
                From android git serveru, codesourcery and etc ..
                - gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android-

        - make output folder 
                EX) OUTPUT_DIR=out
                $ mkdir out

        - edit Makefile
                edit "CROSS_COMPILE" to right toolchain path(You downloaded).
                        EX)  CROSS_COMPILE=<android platform directory you download>/android/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android-
                        Ex)  CROSS_COMPILE=/usr/local/toolchain/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android- // check the location of toolchain
                edit "REAL_CC" to right toolchain path(You downloaded).
                        EX)  CC=<android platform directory you download>/android/vendor/qcom/proprietary/llvm-arm-toolchain-ship/10.0/bin/clang
                edit "CLANG_TRIPLE" to right path(You downloaded).

        - to Build
                $ export ARCH=arm64
                $ make -C $(pwd) O=$(pwd)/out DTC_EXT=$(pwd)/tools/dtc CONFIG_BUILD_ARM64_DT_OVERLAY=y CLANG_TRIPLE=aarch64-linux-gnu- vendor/r8q_eur_openx_defconfig
                $ make -C $(pwd) O=$(pwd)/out DTC_EXT=$(pwd)/tools/dtc CONFIG_BUILD_ARM64_DT_OVERLAY=y CLANG_TRIPLE=aarch64-linux-gnu-

2. Output files
        - Kernel : arch/arm64/boot/Image
        - module : drivers/*/*.ko

3. How to Clean
        Change to OUTPUT_DIR folder
        EX) /home/dpi/qb5_8814/workspace/P4_1716/android/out/target/product/r8q/out
        $ make clean

can you try the clang video. and why you're editing makefile. i haven't mentioned these things that you posted above.

[privacyguy123]

haven't edited anything yet.

I've watched the clang video yes, my kernel is expecting different environment variables than the one in your vid

Only getting errors so far

can you post the commands that you've executed before running the compilation and also your make command with all options

[Shubhamvis98]

as per the logs, seems like you forget to run make defconfig. you can see the error Configuration file ".config" not found!
