h1. BuildEnvironments

h2. Rationale

Each revision of Android is meant to be compiled with a specific set of dependencies. No effort is made upstream to support multiple build environments.

Building with different environments often yields build errors due to untested dependencies versions.

So we document here how to recreate these recommended build environments.

You'll need git > 1.7.2 for @repo@:

<pre>

lxc-start -n replicant -d

lxc-attach -n replicant

# 'lxcguest' fixes a number of issues but seem to disable init..

dhclient

/etc/init.d/ssh restart

cd /usr/src/

apt-get install wget gcc libssl-dev zlib1g-dev libcurl4-gnutls-dev libexpat-dev gettext

wget https://www.kernel.org/pub/software/scm/git/git-2.4.6.tar.gz

tar xf git-2.4.6.tar.gz 

cd git-2.4.6/

make -j4  # ~2mn

make install prefix=/usr/local

</pre>

h2. Ubuntu 10.04 Lucid with LXC

<pre>

apt-get install ubuntu-archive-keyring

lxc-create -n replicant -t ubuntu -- -r lucid -a amd64

lxc-start -n replicant -d

lxc-attach -n replicant

# 'lxcguest' fixes a number of issues but seem to disable init..

dhclient

/etc/init.d/ssh restart

# clean-up non-free sources

sed -i -e 's/ restricted//' -e 's/ multiverse//' /etc/apt/sources.list

apt-get update

cd /usr/src/

apt-get install wget gcc libssl-dev zlib1g-dev libcurl4-gnutls-dev libexpat-dev gettext

wget https://www.kernel.org/pub/software/scm/git/git-2.4.6.tar.gz

tar xf git-2.4.6.tar.gz 

cd git-2.4.6/

make -j4  # ~2mn

make install prefix=/usr/local

</pre>

h2. LXC host environment

The simplest way to configure LXC is to combine it with libvirt.

Here are instructions tested on a Debian 8 host:

<pre>

apt-get install lxc debootstrap

apt-get install libvirt-bin dnsmasq ebtables

service dnsmasq stop

update-rc.d dnsmasq remove

virsh net-autostart default

service libvirtd restart

cat > /etc/lxc/default.conf <<'EOF'

lxc.network.type = veth

lxc.network.flags = up

lxc.network.link = virbr0

EOF

</pre>

You now can run the LXC containers instructions above.

h2. Non-privileged user setup

This can be used in any environment to prepare a non-root user dedicated to builds.

<pre>

# prepare build user

apt-get install openssh-server

useradd replicant --shell /bin/bash --create-home

mkdir -p -m 700 ~replicant/.ssh

cat <<EOF >> ~replicant/.ssh/authorized_keys

your public key

EOF

chown -R replicant: ~replicant

</pre>
