Building

Setup

Android

• Download Android NDK r10e from https://developer.android.com/ndk/downloads/older_releases.html and place it in this directory (Can't automatically download because of EULA)
• Warning: Do not attempt to build use newer or older NDK, it will lead to compilation errors.

iOS

• You should get latest Xcode (tested with Xcode 12).

Platform and architecture specific environment variables

	Environment variables
Platform - Architecture	TARGET	TARGET_JDK
Android - armv8/aarch64	aarch64-linux-android	aarch64
Android - armv7/aarch32	arm-linux-androideabi	arm
Android - x86/i686	i686-linux-android	x86
Android - x86_64/amd64	x86_64-linux-android	x86_64
iOS/iPadOS - armv8/aarch64	aarch64-macos-ios	aarch64

Run in this directory:

export BUILD_IOS=1 # only when targeting iOS, default is 0 (target Android)

export BUILD_FREETYPE_VERSION=[2.6.2/.../2.10.4] # default: 2.10.4
export JDK_DEBUG_LEVEL=[release/fastdebug/debug] # default: release
export JVM_VARIANTS=[client/server] # default: client (aarch32), server (other architectures)
export NDK_VERSION=[r25c/.../r10e]

1 Setup Target JDK and Target NDK by calling the arch specific script

(1_ci_build_arch_[aarch32|aarch64|x86|x86_64].sh) for your desired target.

### (1_ci_build_arch_[aarch32|aarch64|x86|x86_64].sh)
. 1_ci_build_arch_aarch32.sh # for arm
. 1_ci_build_arch_aarch64.sh
. 1_ci_build_arch_x86.sh # for i686
. 1_ci_build_arch_x86_64.sh

2 Download and Setup NDK, run once (Android only)

. setdevkitpath.sh
wget -nc -nv -O android-ndk-$NDK_VERSION-linux-x86_64.zip "https://dl.google.com/android/repository/android-ndk-$NDK_VERSION-linux.zip"
unzip -q android-ndk-$NDK_VERSION-linux-x86_64.zip

3 Get CUPS, Freetype

./3_getlibs.sh

4 Build the libs

./4_buildlibs.sh

5 Clone JDK, run once

./5_clonejdk.sh

6 Configure JDK and build,

If no configuration is changed, run makejdkwithoutconfigure.sh instead

./6_buildjdk.sh

7 Remove/Strip JDK debug info

./7_removejdkdebuginfo.sh

8 Pack the built JDK

./8_tarjdk.sh
