This project contains scripts and patches to cross compile and package packages for
the [Termux](https://termux.com/) Android application.
This project contains scripts and patches to build packages for the
[Termux](https://termux.com/) Android application.
The scripts and patches to build each package is licensed under the same license as
the actual package (so the patches and scripts to build bash are licensed under
the same license as bash, while the patches and scripts to build python are licensed
under the same license as python, etc).
NOTE: This is in a rough state - be prepared for some work and frustrations, and give
feedback if you find incorrect our outdated things!

Build environment on Ubuntu 16.04
=================================
Packages are normally built using Ubuntu 16.04. Most packages should build also under
other Linux distributions (or even on OS X), but those environments will need manual setup
adapted from the below setup for Ubuntu:
Packages are built using Ubuntu 16.04. Perform the following steps to configure a Ubuntu 16.04 installation:
* Run `scripts/setup-ubuntu.sh` to install required packages and setup the `/data/` folder.
* Run `scripts/setup-android-sdk.sh` to install the Android SDK and NDK at `$HOME/lib/android-{sdk,ndk}`.
- Run `scripts/setup-ubuntu.sh` to install required packages and setup the `/data/` folder.
- Run `scripts/setup-android-sdk.sh` to install the Android SDK and NDK at `$HOME/lib/android-{sdk,ndk}`.
Build environment using Docker
==============================
A Docker container configured for building images can be downloaded and run with:
On other Linux distributions than Ubuntu 16.04 (or on other platforms than Linux) the best course
of action is to use Docker to setup a build environment.
A Docker container for building packages can be setup with:
./scripts/run-docker.sh
This will set you up with a interactive prompt in a container, where this source folder
is mounted as the /root/termux-packages data volume, so changes are kept in sync between
the host and the container when trying things out before committing, and built deb files
will be available on the host in the `debs/` directory just as when building on the host.
This will setup a container (from an image created by [scripts/Dockerfile](scripts/Dockerfile))
suitable for building packages.
This source folder is mounted as the /root/termux-packages data volume, so changes are kept

Build commands can be given to be executed in the docker container directly:
