C/C++ Cross compiling environment containers

This has been designed to run libtorrent-go cross compilation and is not meant to be perfect nor minimal. Adapt as required.

Overview

Environment variables

• CROSS_TRIPLE
• CROSS_ROOT
• LD_LIBRARY_PATH
• PKG_CONFIG_PATH

Installed packages

Based on Debian Stretch:

• bash
• curl
• wget
• pkg-config
• build-essential
• make
• automake
• autogen
• libtool
• libpcre3-dev
• bison
• yodl
• tar
• xz-utils
• bzip2
• gzip
• unzip
• file
• rsync
• sed
• upx

And a selection of platform specific packages (see below).

Download and Build

• First, you need Docker and golang

• Create Go home folder and set $GOPATH environment variable:

    mkdir ~/go
    export GOPATH=~/go
  

• Download libtorrent-go:

    go get github.com/ElementumOrg/libtorrent-go
    cd ~/go/src/github.com/ElementumOrg/libtorrent-go
  

• Pull the cross-compiler image for your platform:

    make pull PLATFORM=android-arm
  

• Next, you need to prepare Docker environments. You can do it with two ways:

    make envs
  

  This will download and build all needed development packages and could take hours. But it can be necessary if you want to make your own customizations.

  You can also prepare specific environments like so:

    make env PLATFORM=android-arm
  

• (Optionally) Build locally without Docker (for local development, for example)

  Is helpful if you need to have all the required stack locally on your OS. You need to specify CROSS_TRIPLE - you can find possible values here. Everything is installed in libtorrent-go/local-env/ directory.

    make local-env CROSS_TRIPLE=x86_64-linux-gnu
  

  Then you can run libtorrent-go module compilation:

    make re TARGET_OS=linux TARGET_ARCH=x64 CROSS_ROOT=local-env
  

  It will make sure to use libtorrent-go/local-env/lib/pkgconfig/ to compile module and have all the dependencies. But before that you also need to install swig.

• Build libtorrent-go:

    make [ android-arm | android-arm64 | android-x86 | android-x64 |
           linux-x86   | linux-x64     | linux-armv6 | linux-armv7 | linux-arm64 |
           windows-x86 | windows-x64   | 
           darwin-x64  | darwin-x86 ]
  

  To build libtorrent bindings for all platforms use make or specify needed platform, e.g. make android-arm. Built packages will be placed under ~/go/pkg/<platform>

Release

Release is done by running release.sh script, that compiles all Docker images and pushes them to Docker Hub.
