Cross compiling Android

Guide for cross compiling mobile library for android from Ubuntu 22.10 x86_64

Install build tools

This is the subset of tools from the README used to compile the mobile android library

# apt-get update
# apt-get install make screen autoconf libtool git

You can view which target android platforms are available with. As well as viewing the currently configured environment

make env-android

These platforms can be specified by setting the PLATFORM= variable

there is an install script that will download the required tools to build

It will do 4 things

Download a ldc compiler for the host
Download a ldc compiler for the target platform, which includes the necessary libraries
Download the android ndk, which includes android specific c compiler and linkers
Configure the host compiler to use the android specific libraries and tools

make PLATFORM=aarch64-linux-android install-android-toolchain

make DC=tools/ldc2-1.35.0-linux-x86_64/bin/ldc2 PLATFORM=aarch64-linux-android libmobile

If you have installed the android ndk in a different location you may configure it with ANDROID_NDK=

ANDROID_NDK=tools/android-ndk-r21b/

The android target defaults to using the D compiler installed by the script.
You have to override it if you want to use a different compiler.

DC=/path/to/my/ldc/bin
