Overview

ZenMaxBuilder (ZMB) is a Linux kernel builder written in Bash and oriented for android devices but as well compatible for other platforms. It can be installed on any compatible Linux system (feel free to Pull Request for win/mac support). By default it uses AOSP-Clang, Eva-GCC, Proton-Clang, Neutron-Clang or Lineage-GCC but you can use any Clang or GCC toolchain you like (with LLVM and binutils included).

Find all your compilations and working folders in one place, update and maintain your kernels faster. Full logs with the possibility to restart the build after error. Automatic creation of a flashable signed ZIP for android devices (with AK3 and AOSP Keys). Real time status feedback with build sending on any group or Telegram channel. And more. The perfect tool to compile on the fly and keep fresh and clean kernel paths.

Requirements

• A compatible Linux system
• The kernel source code of your device/os
• A minimum of knowledge in kernel compilation
• Patience

The installation of the missing dependencies will be proposed by the installer or first install them manually with your favorite package manager (no package is installed without your prior consent) :

bash sed wget git curl zip tar jq expect make cmake automake autoconf llvm lld lldb clang gcc binutils bison perl gperf gawk flex bc python3 zstd openssl sudo

The optional flashable zip signature with AOSP Keys requires java (JDK) which is not proposed to install (openjdk recommended).

Installation

The installer simply clones the repository in your HOME and creates a copy of the executable in usr/bin.

Install ZenMaxBuilder :

wget kernel-builder.com/zmb && bash zmb install

Checking the installation :

bash ~/ZenMaxBuilder/docs/zmb check

Update ZenMaxBuilder :

zmb --update

Uninstall ZenMaxBuilder :

bash ~/ZenMaxBuilder/docs/zmb uninstall
rm -rf ~/ZenMaxBuilder

Guetting Started

Create a copy of settings.cfg to set your settings (optional) :

cp ~/ZenMaxBuilder/etc/settings.cfg ~/ZenMaxBuilder/etc/user.cfg
vi ~/ZenMaxBuilder/etc/user.cfg

Start ZMB and follow instructions :

zmb --start

You can exit ZMB at any time using ctrl+c or ctrl+z combinaison keys.

Options

Usage: zmb [OPTION] [ARGUMENT] (e.g. zmb --info zenfone pro)

    -i, --info        [device]      mobile device specifications
    -m, --msg        [message]      send message on Telegram
    -f, --file          [file]      send file on Telegram
    -z, --zip          [image]      create new kernel zip
    -p, --patch                     apply a patch to a kernel
    -r, --revert                    revert a patch to a kernel
    -d, --debug                     start compilation in debug mode

Toolchains

ZMB uses prebuilt toolchains by default (built on x86-64 interpreter: lib64/ld-linux-x86-64.so.2).

In case you need others or have already compiled/downloaded some, just move them to the toolchains folder and name them aosp-clang for example (see settings.cfg).

More information

ZMB is a tool to facilitate the compilation of the Linux kernel, it does not modify the source, does not adds possible patchset and does not fixes specific drivers or compilation warnings.

The only change made is the addition of the selected toolchain compiler in the main Makefile, all others options from ZMB settings will be passed directly to make as command-line arguments :

# AOSP-Clang
CROSS_COMPILE ?= aarch64-linux-android-
CC             = clang

# Proton-Clang / Neutron-Clang
CROSS_COMPILE ?= aarch64-linux-gnu-
CC             = clang

# Eva-GCC
CROSS_COMPILE ?= aarch64-elf-
CC             = aarch64-elf-gcc

# Lineage-GCC
CROSS_COMPILE ?= aarch64-linux-android-
CC             = aarch64-linux-android-gcc

Common warnings and errors

• invalid kernel directory : occurs while the ARCH option is not matching the selected kernel directory (or while KERNEL_DIR is not correctly set), edit user.cfg accordingly.

• your system does not support this prebuilt of : occurs while the included prebuilt toolchains are not compatible with your system, you can disable HOST_LINKER in user.cfg but the build will fail in most cases. System compatible toolchains are required or you can try host compiler option.

• CROSS_COMPILE not found in Makefile : occurs while your source is configured to pass CROSS_COMPILE to make as command-line argument. You can ignore this warning except if you deactivated MAKE_CMD_ARGS.

• CROSS_COMPILE may not be set correctly in Makefile : occurs while another compiler is defined in the main Makefile. You can ignore this warning and answer yes while ZMB asking to set it up for you.

• failed to add toolchain bin to the PATH : occurs while the PATH is not correctly set, please open an issue.

• An error occurs while getting the kernel version : in most cases your source is not configured to be built with the selected toolchain compiler. Try another compiler or answer yes while purposed and edit your Makefile accordingly.

• kernel version not found : same as above or issue with your source.
