First Thanks to PrabhuSundararaj for sharing his knowledge and tips to be able to accomplish all these steps.
With our new release of wayland coming soon, many of you would like to see it working with the latest Qt. The process might sound complicated, but it is simpler than it seems.
Once you get in your hands the newest release sources then follow the MX6_Wayland_Weston_User_Guide_Review.pdf for the instructions to install your Ltib and compile the rootfs. I was successful creating the rootfs with Gnome profile selected.
Pay a lot of attention to step 8
8 Enabling Wayland/Weston Support for Prebuilt rootfs in
LTIB File System
The prebuilt root file system (rootfs) comes with prebuilt GPU driver. By default, it is 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
$ ls –l $(ROOTFS)/usr/lib/libGAL.so
libGAL.so -> libGAL-wl.so
The manual only advices to change libEGL.so link to libEGL-wl.so, but you also have to change libEGL.so.1 link, it should point to libEGL-wl.so as well.
ln -s libEGL-wl.so libEGL.so
ln -s libEGL-wl.so libEGL.so.1
ln -s libGAL-wl.so libGAL.so
Once building the rootfs is successful, please test that it boots correctly and start weston correctly.
$start-weston
$export LD_LIBRARY_PATH="/usr/lib"
$export XDG_RUNTIME_DIR="/tmp"
Proceed to QT5 build. Please follow the guide to build QT5.
https://community.freescale.com/docs/DOC-94066
Pay attention that the rootfs now is the one created with the wayland release.
For example this configure line:
./configure -opensource -confirm-license -make libs -device imx6 -device-option CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- -sysroot /home/b35153/waylandRootfs/ltib/rootfs -no-gcc-sysroot -prefix /opt/qt5wayland -no-pch -no-opengl -opengl es2 -no-xcb -make examples -make demos
After completing the guide, the next step is to build the Qtwayland plug-in.
1. Download the git repository for Qtwayland:
$ git clone git://gitorious.org/qt/qtwayland.git
$ cd qtwayland
2. gedit src/plugins/platforms/qwayland-egl/qwayland-egl.pro
and make the change as like this, please be careful on not to break the syntax:
Delete these lines:
!contains(QT_CONFIG, no-pkg-config) {
CONFIG += link_pkgconfig
PKGCONFIG += wayland-egl egl
} else {
LIBS += -lwayland-egl -lEGL
}
Replace them with this line
LIBS += -lEGL
3. cd to <qtwayland directory>/qtwayland and run the qmake
(qmake should be in the PATH, or you can specify the full path to qmake)
$ qmake -r
The qtwayland will test certain packages. The summary should look like this:
Checking for wayland... yes
Checking for xkbcommon... yes
Checking for brcm_egl... no
Checking for egl... yes
Checking for glx... no
Checking for wayland_egl... yes
Checking for xcomposite... no
If you have an error about the wayland-scanner not detected, disable the check at the qtwayland.pro
#!config_wayland_scanner {
# error(QtWayland requires wayland-scanner)
#}
4. Build
make && sudo make install
Ater this step you should be able to run demos using the wayland-egl platform like this:
$ ./forest_qml -platform wayland-egl
Now in order to install Qt3D follow this guide:
https://community.freescale.com/docs/DOC-94236
And
$./shaders -platform wayland-egl
Voila!
