Compiling FreeType (2.6.3) using Android NDK.

My setup:

• OpenSuse Linux Leap 42.1.20151028 x86_64 (64Bit), AMD Athlon X2
• Android NDK r10e-rc4 (64-bit). Directory name android-ndk-r10e-linux
• Terminal / Bash shell. On Windows one needs to install binutils, development environment. Just install CodeBlocks windows or other such compiler. They contain most of needed tools.

Before starting please read setup and brief of how libpng is compiled. It is a waste if I write same thing repeatedly.

Link: http://www.ourinnovativemind.in/2016/03/how-to-compile-libpng-using-android-ndk.html


Starting steps same as libpng project:

• Download Android NDK and extract/install to a path without containing space or special characters. If using Linux then make symbolic link to home.
• Download FreeType package version 2.6.3
• Create a working directory where package will be compiled. Extract package.

# AndroidBuild.sh START

#!/bin/sh
# http://www.ourinnovativemind.in
# http://www.gamesgreh.in

# Add configure options here
export CONFIGURATION_OPTIONS="--enable-static --disable-shared --with-bzip2=no"

# use custom build environment

# installation directory
export PREFIX=`pwd`/prefix

# Path of NDK. For simplicity make symlinks in home directories
export NDK=/mnt/work/SDK_IDE/android-ndk-r10e-linux/

# processor specific libraries and includes.
# Suffix for arch-???. arch-arm arch-arm64 arch-mips arch-mips64 arch-x86 arch-x86_64
export ARCH=arm

# compiler for processor
export CROSS_COMPILE=arm-linux-androideabi

# Android platform version
export PLATFORM=android-8

# GCC compiler version
export GCC_VERSION=4.8


# Getting toolchain directory inside NDK from variables set above
# Hardcoded for linux running on x86 cpu 64-Bit
export ANDROID_PREFIX=${NDK}/toolchains/$CROSS_COMPILE-$GCC_VERSION/prebuilt/linux-x86_64

# SYSROOT. usr dir i.e. usr/include, usr/lib
export SYSROOT=${NDK}/platforms/$PLATFORM/arch-$ARCH
export CROSS_PATH=${ANDROID_PREFIX}/bin/${CROSS_COMPILE}

# Some compiler and binutils. More might be needed depending on source.
export CPP=${CROSS_PATH}-cpp
export AR=${CROSS_PATH}-ar
export AS=${CROSS_PATH}-as
export NM=${CROSS_PATH}-nm
export CC=${CROSS_PATH}-gcc
export CXX=${CROSS_PATH}-g++
export LD=${CROSS_PATH}-ld
export RANLIB=${CROSS_PATH}-ranlib

# package configuration file save location
export PKG_CONFIG_PATH=${PREFIX}/lib/pkgconfig

# Flags for compiler
export CFLAGS="${CFLAGS} --sysroot=${SYSROOT} -I${SYSROOT}/usr/include -I${ANDROID_PREFIX}/include"
export CPPFLAGS="${CFLAGS}"
export LDFLAGS="${LDFLAGS} -L${SYSROOT}/usr/lib -L${ANDROID_PREFIX}/lib"

#$@
./configure --host=${CROSS_COMPILE} --with-sysroot=${SYSROOT} --prefix=${PREFIX} "$@" $CONFIGURATION_OPTIONS
make
make install

# AndroidBuild.sh END







Copy all lines above and paste in a new file AndroidBuild.sh and save. Then change the variables valid for your system. Create folder prefix or whatever name you like. Change NDK=/mnt/work/SDK_IDE/android-ndk-r10e-linux/ and compiler related values as per your system. This script copied from web can cause error due to removal of newlines for strange reasons. Ensure # is ahead of comments. Now run sh AndroidBuild.sh. It should end without errors. This will install all built files in prefix directory.

FreeType build system -- automatic system detection

The following settings are used:

platform unix
compiler /mnt/work/SDK_IDE/android-ndk-r10e-linux//toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk

If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.

Otherwise, simply type `make' again to build the library,
or `make refdoc' to build the API reference (this needs python >= 2.6).
