Distribution

The release rootfs image is based on linaro-alip-jessie.If you want to use other distributions, you need to compile and install components we provide.Do not install the deb under rk-rootfs-build directly.

We currently provide several components, the guide below only help you make xserver work.
For more details Please refer to each package's wiki.

There are also many other districbutions support by community or developers.

Ubuntu 16.04

download and extract ubuntu-xenial

wget [http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04-core-armhf.tar.gz http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04-core-armhf.tar.gz]
sudo tar -xpf ubuntu-base-16.04-core-armhf.tar.gz

copy qemu

sudo apt-get install qemu-user-static
sudo cp /usr/bin/qemu-arm-static usr/bin/

copy host's dns to rootfs

sudo cp -b /etc/resolv.conf  etc/resolv.conf

add the following repository to etc/apt/source.list(for compiling xserver)

deb [http://ports.ubuntu.com/ubuntu-ports/ http://ports.ubuntu.com/ubuntu-ports/] xenial main universe
deb-src [http://ports.ubuntu.com/ubuntu-ports/ http://ports.ubuntu.com/ubuntu-ports/] xenial main universe

chroot to target rootfs
ch-mount.sh

ch-mount.sh -m ubuntu/

install desktop

apt-get install lightdm vim git
apt-get build-dep xserver-xorg-core

extract libmali-rk-dev_1.4-4_armhf.deb and libmali-rk-midgard0_1.4-4_armhf.deb（only debian/ubutnu, link by yourself if you are using other distributions） and copy them to target system.
delete origin egl,gles library(For insurance)

rm -rf /usr/lib/arm-linux-gnueabihf/mesa-egl

download xserver

git clone [https://github.com/rockchip-linux/xserver.git https://github.com/rockchip-linux/xserver.git]

delete those in configure.ac

AC_CHECK_DECL(GBM_BO_USE_LINEAR,
                        [AC_DEFINE(GLAMOR_HAS_GBM_LINEAR, 1, [Have GBM_BO_USE_LINEAR])], []

build xserver
(You can also use 'make install DESTDIR=/opt/x-build' to get files and copy them to a clean system)
(This method is easy but slow, it'better to cross compile xserver under the ubuntu/debian multiarch environment)

./autogen.sh --prefix=/usr --enable-aiglx --enable-composite --enable-record --enable-xv --enable-xvmc --enable-dga --enable-screensaver --enable-xdmcp --enable-xdm-auth-1 --enable-glx --enable-dri --enable-dri2 --enable-glamor --enable-dri3 --enable-libdrm --enable-present --enable-xinerama --enable-xf86vidmode --enable-xace --enable-xselinux --enable-xfree86-utils --enable-xwayland --enable-systemd-logind --with-systemd-daemon --enable-suid-wrapper --enable-dmx --enable-xvfb --enable-xnest --enable-kdrive --enable-xephyr --enable-xmir --with-sha1=libgcrypt --enable-xcsecurity  --with-log-dir=/var/log
make
make install

set password

useradd -s '/bin/bash' -m -G adm,sudo rk
echo "Set password for rk:"
passwd rk
echo "Set password for root:"
passwd root

exit chroot

exit
ch-mount.sh -u ubuntu/

copy ttyS2.conf and udev directory to target rootfs from rk-rootfs.build

make image

dd if=/dev/zero of=ubuntu.img  bs=1M count=3000
sudo mkfs.ext4 ubuntu.img
mkdir ubuntu-mount
sudo mount  ubuntu.img ubuntu-mount
sudo cp -rfp ubuntu ubuntu-mount
sudo umount ubuntu-mount
e2fsck -p -f ubuntu.img
resize2fs -M ubuntu.img

update

There is a ubuntu build script in our rootfs-build repo. It's different from the above example, it unpack the debian packages rather than compile from source.
Please refer to the readme.
