Instructions

1. Download Wind River Linux LTS 19.

   Clone the Wind River Linux repository into a new project directory.

   git clone -b WRLINUX_10_19_BASE https://github.com/WindRiver-Labs/wrlinux-x.git
   

2. Configure Wind River Linux in a new build directory.

   mkdir wrlinux-ros2
   cd wrlinux-ros2
   

   For Raspberry Pi 4 use:

   ../wrlinux-x/setup.sh --machines=bcm-2xxx-rpi4 --distros=wrlinux --dl-layers
   

   For Intel 64 use:

   ../wrlinux-x/setup.sh --machines=intel-x86-64 --distros=wrlinux --dl-layers
   

3. Add the additional layers.

   cd layers
   git clone -b zeus https://github.com/ros/meta-ros.git
   git clone https://github.com/Wind-River/meta-robot.git
   git clone https://github.com/Wind-River/wr-ros.git
   git clone -b zeus https://github.com/IntelRealSense/meta-intel-realsense.git
   

4. (Optional Qt) Add the Qt5 layers.

   git clone -b zeus https://github.com/meta-qt5/meta-qt5.git
   git clone -b zeus https://github.com/schnitzeltony/meta-qt5-extra.git
   

5. Return to the wrlinux-ros2 directory.

   cd ..
   

6. Initialize the build environment.

   . ./environment-setup-x86_64-wrlinuxsdk-linux
   . ./oe-init-build-env wrlinux-lts19-ros2
   

7. Configure Bitbake layers. Use bitbake-layers to add the ROS2 layers to your BitBake configuration.

   This section assumes that you have sourced the OpenEmbedded build environment in the previous step.

   cd $BUILDDIR
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-ros/meta-ros-common
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-ros/meta-ros2
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-ros/meta-ros2-foxy
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-ros/meta-ros-backports-dunfell
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/wr-ros
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-intel-realsense
   

8. (Optional Raspberry Pi 4) Add the rpi-graphics layer for hardware acceleration.

   bitbake-layers add-layer ../layers/bcm-2xxx-rpi/rpi-graphics/
   

9. (Optional Qt) Add the Qt5 layers.

   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-qt5
   bitbake-layers add-layer $(readlink -f $BUILDDIR/../layers)/meta-qt5-extra
   

10. (Optional Qt) Download and patch the unsupported Qt5 integration for Wind River Linux.

    cd $BUILDDIR/../layers/wrlinux
    
    curl -O https://labs.windriver.com/downloads/0001-wrlinux-template-add-template-qt5-for-wrlinux.patch
    git am 0001-wrlinux-template-add-template-qt5-for-wrlinux.patch
    
    curl -O https://labs.windriver.com/downloads/0002-wrlinux-template-add-lxqt-support-for-wrlinux.patch
    git am 0002-wrlinux-template-add-lxqt-support-for-wrlinux.patch
    
    cd $BUILDDIR/../layers/meta-qt5-extra
    
    curl -O https://labs.windriver.com/downloads/0001-polkit-qt-1-fix-compile-error.patch
    git am 0001-polkit-qt-1-fix-compile-error.patch
    
    cd $BUILDDIR
    

11. Modify local configuration.

    Enable network access for fetching source tarballs and disable all the whitelist layers.

    Add the following to the end of conf/local.conf

    BB_NO_NETWORK = '0'
    PNWHITELIST_LAYERS = ""
    DISTRO_FEATURES_append = " x11 opengl vulkan polkit"
    IMAGE_INSTALL_append += " packagegroup-ros-world"
    
    SYSROOT_DIRS_append += " ${nonarch_libdir} "
    FILES_${PN}-dbg += "${nonarch_libdir}/.debug"
    FILES_${PN}-dev += "${nonarch_libdir}/pkgconfig ${nonarch_libdir}/cmake"
    FILES_${PN} += "${nonarch_libdir}/lib*.so*"
    FILES_${PN} += "${nonarch_libdir}/${ROS_BPN}"
    FILES_${PN} += "${nonarch_libdir}/${PYTHON_DIR}"
    FILES_${PN}-dev += "${nonarch_libdir}/${PYTHON_DIR}/site-packages/*.la"
    FILES_${PN}-staticdev += "${nonarch_libdir}/lib*.a"
    FILES_${PN}-staticdev += "${nonarch_libdir}/${PYTHON_DIR}/site-packages/*.a"
    INSANE_SKIP_${PN}-dbg += "libdir"
    INSANE_SKIP_${PN} += "dev-so libdir"
    

12. (Optional Graphics) Add support for OpenGL graphics with demo examples.

    IMAGE_INSTALL_append += "\
    xserver-xorg \
    xserver-xorg-extension-glx \
    mesa \
    mesa-demos"
    

13. (Optional) For building applications on the device add the following lines.

    IMAGE_INSTALL_append += "\
    packagegroup-core-buildessential \
    git"
    

14. (Optional Qt) Add qt5 to the configuration.

    Edit the conf/local.conf again to add the following lines:

    WRTEMPLATE = "feature/qt5 feature/lxqt"
    ROS_WORLD_SKIP_GROUPS_remove = "world-license"
    ROS_WORLD_SKIP_GROUPS_remove = "turtlebot3"
    ROS_WORLD_SKIP_GROUPS_remove = "qt-gui-cpp"
    ROS_WORLD_SKIP_GROUPS_remove = "world-license-faad"
    PACKAGECONFIG_append_pn-qtbase-native = " gui"
    

15. Set the license flags whitelist to allow the use of commercial graphics drivers.

    LICENSE_FLAGS_WHITELIST = "commercial"
    

16. Remove webots from packagegroup-ros-world-foxy.

    Edit the conf/local.conf again to add the following lines:

    ROS_WORLD_SKIP_GROUPS += "webots-python-modules"
    
    RDEPENDS_packagegroup-ros-world-foxy_remove += " \
        webots-ros2-epuck \
        webots-ros2-tiago \
        webots-ros2-universal-robot \
    "
    

17. (Optional Raspberry Pi) Edit cmdline.txt to adjust the kernel parameters.

    $ cat ../layers/bcm-2xxx-rpi/recipes-bsp/boot-config/boot-config/cmdline.txt
    dwc_otg.lpm_enable=0 console=serial0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ip=dhcp
    $ echo 'dwc_otg.lpm_enable=0 console=tty root=/dev/mmcblk0p2 rootfstype=ext4 rootwait' > ../layers/bcm-2xxx-rpi/recipes-bsp/boot-config/boot-config/cmdline.txt
    

    Note: These changes ensure that the console output appears on the HDMI display and that the boot sequence doesn't wait for a DHCP connection.

18. Build Wind River Linux standard filesystem

    bitbake wrlinux-image-std
    

19. (Optional Graphics) Build Wind River Linux with graphics.

    bitbake wrlinux-image-std-sato
