aseprite-termux

This guide will show you how to build the animated sprite and pixel art tool aseprite for termux-x11.

The building process requires around 8GB of empty storage.

NOTE: Android 8 or higher is required in order to build and run aseprite (pthread_getname_np is needed and only available after Android 8)

repo branches used in this guide:

Aseprite: main 1ec76af
Skia: aseprite-m102 857111b

Steps

install essential packages for compilation

pkg install x11-repo

pkg install build-essential gn libglvnd* libx11 libxcursor libxi xdg-utils

clone skia and aseperite

cd $HOME
git clone --recursive https://github.com/aseprite/aseprite.git

mkdir $HOME/deps
cd $HOME/deps
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
git clone -b aseprite-m102 https://github.com/aseprite/skia.git
cd skia
python tools/git-sync-deps

apply patches required to build
