Building Wayland-Weston for i.MX6

1 Kudo

The instructions is based on building wayland-weston on Ubuntu prebuilt image. The same can be applied to other build systems as well.

PREREQUISITIES

The following is the software environment required:

- Ubuntu Oneiric (11.10) distribution. (Download Pre-built Ubuntu demo image from www.freescale.com/imx6)

- Wayland/Weston : Wayland dependencies are listed in http://wayland.freedesktop.org/building.html.

- 0001-DRM-condition.patch and 0002-Enable-weston-for-Vivante-GPU.patches for Weston.

WAYLAND VERSION

This release is based on Wayland 1.1.0 version.

BUILDING

The steps are based on wayland building from http://wayland.freedesktop.org/building.html.
Download wayland-1.1.0.tar.xz from http://wayland.freedesktop.org/releases.html

3. Setting up the environment. This need to be performed on the target

$export WLD=/usr

$export LD_LIBRARY_PATH=$WLD/lib

$export PKG_CONFIG_PATH=$WLD/lib/pkgconfig/:$WLD/share/pkgconfig/

$export ACLOCAL="aclocal -I $WLD/share/aclocal"

Also, create the 'share/aclocal' directory.

$mkdir -p $WLD/share/aclocal

Let us consider, extracting the package to /opt

$cd /opt

$tar xvvf wayland-1.1.0.tar.xz

$cd wayland-1.1.0

$ ./configure --prefix=$WLD --disable-documentation

$ make

$ make install

4. Setting up GPU-VIV graphics drivers

The GPU-VIV graphics drivers are available as part of BSP release.

Get the gpu-viv-wl-bin-mx6q-{VER}.tar.gz for 4.0.0 release gpu-viv-wl-bin-mx6q-3.0.35-4.0.0.tar.gz from the BSP-Source/pkgs

Extract to the target $ROOTFS

The prebuilt root file system (rootfs) may come with prebuilt GPU driver. By default, it may set to EGL framebuffer.

To enable Wayland/Weston support, make EGL and GAL point to correct binaries as shown below:

$ ls –l $(ROOTFS)/usr/lib/libEGL.so*

libEGL.so -> libEGL-wl.so

libEGL.so.1 -> libEGL-wl.so

$ ls –l $(ROOTFS)/usr/lib/libGAL.so

libGAL.so -> libGAL-wl.so

5. Build the libxkbcommon as in http://wayland.freedesktop.org/building.html

6. We will need Cairo stack as Weston clients depend on Cairo for rendering. Please build Cairo as described in http://wayland.freedesktop.org/building.html, but note that, for now, we do not enable gl backend for Cairo, so the '--enable-gl --enable-xcb' flags must not be used when building.

7. Building Weston

Now add the following environment settings in the terminal window. (Note the "`"- backtick - character).

export WLD=/usr

export LD_LIBRARY_PATH=$WLD/lib

export PKG_CONFIG_PATH=$WLD/lib/pkgconfig/:$WLD/share/pkgconfig/

export ACLOCAL="aclocal -I $WLD/share/aclocal"

export LD_LIBRARY_PATH="/usr/lib"

export LDFLAGS="-lwayland-server -lwayland-client -lwayland-server -lwayland-cursor -lpixman-1"

export COMPOSITOR_LIBS="-lGLESv2 -lEGL -lGAL -lwayland-server -lxkbcommon -lpixman-1"

export COMPOSITOR_CFLAGS="-I $WLD/include -I $WLD/include/pixman-1 -L$SDK_DIR/drivers -DLINUX=1 -DEGL_API_FB -DEGL_API_WL"

export CLIENT_CFLAGS="-I $WLD/include -I $WLD/include/cairo -I $WLD/include/pixman-1"

export CLIENT_LIBS="-lGLESv2 -lEGL -lwayland-client -lwayland-cursor -lxkbcommon"

export SIMPLE_EGL_CLIENT_CFLAGS="-DLINUX=1 -DEGL_API_FB -DEGL_API_WL -I $WLD/include"

export SIMPLE_EGL_CLIENT_LIBS="-lGLESv2 -lEGL -lwayland-client -lwayland-cursor"

export IMAGE_LIBS="-lwayland-cursor"

export WESTON_INFO_LIBS="-lwayland-client"

Apply the two patches 0001-DRM-condition.patch and 0002-Enable-weston-for-Vivante-GPU.patch.

Build the Weston.

$cd /opt

$tar xvvf weston-1.1.1.tar.xz

$ cd weston-1.1.1

$ ./configure --prefix=$WLD \

--disable-setuid-install \

--disable-x11-compositor --disable-drm-compositor \

--disable-rpi-compositor --disable-wayland-compositor \

--disable-weston-launch --disable-libunwind \

--disable-xwayland-test \

WESTON_NATIVE_BACKEND="fbdev-backend.so"

$ make

$ make install

RUNNING

Also, Weston must be run as root. copy weston.ini and weston-desktop-shell.ini to /root/.config/ . In terminal window,

export LD_LIBRARY_PATH="/usr/lib"

export XDG_RUNTIME_DIR=/tmp

Execute 'src/weston'. You should see a blue screen fading in. In a different terminal, enter 'clients/simple-shm &'. You should see a scrolling color pattern. You can then enter 'clients/simple-egl &' to see a 3D client action.

I am trying to compile Wayland and weston to not without X, When I am following the tuto, I get into this problem at compilation time of weston :

---------------------------------------------------------------------------------------------------------------------

checking for XWAYLAND... no

configure: error: Package requirements (xcb xcb-xfixes xcursor cairo-xcb) were not met:

No package 'xcursor' found

No package 'cairo-xcb' found

---------------------------------------------------------------------------------------------------------------------

So I changed the configure option --disable-xwayland-test to --disable-xwayland and then I get that :

---------------------------------------------------------------------------------------------------------------------

checking for FBDEV_COMPOSITOR... no

configure: error: Package requirements (libudev >= 136 mtdev >= 1.1.0 libdrm >= 2.4.30) were not met:

No package 'libudev' found

---------------------------------------------------------------------------------------------------------------------

Is it the good way to get your tuto done ? because systemd does not seem to be in ltib yet ...

And if add to configure --disable-fbdev-compositor

Everything is compiling but no fbdev-backend.so is present at the output ...

aurelienbouin · ‎12-13-2013

.... Up ....

Is there a way to at least build weston and wayland without X with GPU mx6 support with yocto ?

Thanks ...

We are also waiting for the solution. We tried with tuto but never success.

Will there be a tutorial on getting QtWayland and QtCompositor up and running?

Just running Weston will not get the features that one can get when using QtWayland and QtCompositor.

I have wayland/weston running on a debian rootfs using the latest (3.10.17_beta) libraries. Build instructions on the blog. Unfortunately there is still a dependency to pull in some X11 libraries due to cairo/pixman dependencies.

chxie · ‎03-16-2014

Which board do you use?

I use Sabre-lite faced some problem, wayland can't work with QtWayland.

mtx512 · ‎03-17-2014

I have got Wayland + QT + QTWayland working, it seems to be a bit of mission especially since I chose to perform a native compile.

chxie · ‎03-17-2014

thanks for your reply.

I can't open your blog.

do you use ltib or based on any other things?

I use the kernel and rootfs built from timesys(egl from freescale) and compile wayland and Qt by myself, the building is ok, but the Qt + wayland can't work.

could you give me more details about you steps? thanks.

mtx512 · ‎03-17-2014

My rootfs is debian (sid) and kernel 3.10.17 beta.

1. I built wayland/weston from latest sources + my patch http://pastebin.com/x5gumsye

2. Test weston works with -wl libraries

3. Built qt5 from latest source

4. Test qt5 works with -fb libraries

5. Build qtwayland from lastest sources

6. To test qt5 examples need to pass -platform wayland-egl

All compilation was native (very slow) not using cross compilation.

chxie · ‎03-17-2014

get it.

where can I get the debian rootfs and the kernel? is it ok to following i.MX6x SABRE Lite - Linux on ARM - eewiki ?

thanks.

mtx512 · ‎03-17-2014

You can try with that roofts but you need to install vivante libraries.

Alternative you can try my debian sid with xfce rootfs. Use your uboot + kernel (this is for 3.10.9 alpha kernel and GPU (fb+x11) /VPU libraries), however you need to deploy -wl libraries, they are not on the rootfs.

You can update my rootfs to 3.10.17 beta kernel + vivante libraries afterwards.

I have got a iMX6Q board, using rootfs built from LTIB. I am able to run wayland in it without any problem. According to wayland/weston - The Weston Wayland Compositor weston does not call FBIO_WAITFORVSYNC ioctl, from the patch available in this thread it look like weston finishes the frame every ms. How the whole system works without tearing or any rendering issue?

aurelienbouin · ‎04-24-2014

Here is a link where weston has been built successfully : Configuring weston with yocto on i.MX6

FYI it works with yocto :

repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b master

repo sync

MACHINE=X source setup-environment build-X

bitbake core-image-weston

I faced a problem when running "weston-simple-egl".

The terminal shows someinfomation:

[1]HAL user version 4.6.9 build 6622 Aug 16 2013 11:28:30

[2]HAL kernel version 4.6.9 build 1210

Segmentation fault (core dumped)

kernel version : L3.0.35_4.1.0

GPU-VIV : gpu-viv-wl-bin-mx6q-3.0.35-4.1.0

Could anyone tell me what happened?

Hi,

I'm facing the some issue, I need to get wayland working on the imx6 but i'm not understanding the work flow,

Its suposed to build the elf file for the wayland on the host machine ? Or this process has to be done on the target ?

thanks in advance

yenchinlee · ‎10-21-2014

Use yocto to build wayland/weston image on i.MX6 is really easy. Just try it.

Weston on i.MX6 need to patch and currently only work on fb-backend, see the meta-fsl-arm's recipes.

cphealy1 · ‎01-31-2018

If you are willing to us the mainline kernel, you can also run the latest version of Weston without need for any patches. The following blog talks about it:

Etnaviv now supported in Weston mainline
