1. proposal for first try integration of meta-qt5 layer
2. use a dizzy branch of meta-qt5 to correspond with poky and meta-oe dizzy branches from agl
3. URI: https://github.com/meta-qt5/meta-qt5.git
4. branch: dizzy
5. revision: adeca0db212d61a933d7952ad44ea1064cfca747
6. add the qt5 components with own packagegroups under /meta-agl/meta-agl/recipes-ivi

1. for the first try of integration of qt5 into agl-image-ivi we take:

get git url for agl from here and see the README.md how to use: https://git.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl.git;a=blob;f=README.md;h=a92dfe8de4e6614a8d4dbbaaddbccaa06f1e4c75;hb=4e6823fb7a9763715fb554cfb0df2dc318d741a7 URI: git:git.yoctoproject.org/poky

1. …../meta-agl/meta-agl/recipes-ivi/packagegroups/packagegroup-agl-ivi-qt5.bb
   1. which contains the qt5 packages to be used for agl

……/meta-agl/meta-agl/recipes-ivi/packagegroups/packagegroup-agl-ivi-qt5-examples.bb

1. which contains the qt5 examples packages to be used for agl

to make qt and qt examples part of your image, add the two new packagegroup files to -…../meta-agl/meta-agl/recipes-ivi/packagegroups/packagegroup-agl-ivi.bb -which includes all the ivi packagegroup files ————————————————————————————————————————– 3. to run a successful build you also might have to fix the following build problems 3.1 with the version i have used for qt integration i had the following build problem /fix the build problem of gstreamer bbappend version in meta renesas

/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/common/recipes-multimedia/gstreamer/gstreamer1.0-plugins-base_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/meta-rcar-gen2/recipes-multimedia/gstreamer/gstreamer1.0-plugins-base_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/common/recipes-multimedia/gstreamer/gstreamer1.0-libav_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/meta-rcar-gen2/recipes-multimedia/gstreamer/gstreamer1.0-plugins-ugly_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/meta-rcar-gen2/recipes-multimedia/gstreamer/gstreamer1.0-omx_1.0.0.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/common/recipes-multimedia/gstreamer/gstreamer1.0-plugins-good_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/meta-rcar-gen2/recipes-multimedia/gstreamer/gstreamer1.0-plugins-good_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/common/recipes-multimedia/gstreamer/gstreamer1.0_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/common/recipes-multimedia/gstreamer/gstreamer1.0-plugins-bad_1.2.3.bbappend
/path/to/project/AGL-GENIVI-7.0/poky/../meta-renesas/meta-rcar-gen2/recipes-multimedia/gstreamer/gstreamer1.0-plugins-bad_1.2.3.bbappend

I solved the problem of using the component version XXX_1.2.3.bbappend by changing it to wildcard format XXX_%.bbappend.  The problem originally occured by using the new poky version. For the future we have to see if this fix is applicable

3.2 modified file for gstreamer1.0-plugins-base problem

in file:  ...../meta-renesas/meta-rcar-gen2/recipes-multimedia/gstreamer/gstreamer1.0-plugins-base_%.bbappend

change do_configure

from:
do_configure() {
  ./autogen.sh --noconfigure
  oe_runconf
}

to:
do_configure() {
  (cd ${S} && ./autogen.sh --noconfigure)
  oe_runconf
}

3.3 add some config options in qtbase.inc

add icu in qtbase.inc, because its necessary to have qtwebkit … PACKAGECONFIG_ICU ?= “icu” … PACKAGECONFIG ?= “ \ … ${PACKAGECONFIG_ICU} \ ” add examples in qtbase.inc, because its necessary to have qt examples in rootfs

… PACKAGECONFIG_EXAMPLES ?= “examples” … PACKAGECONFIG ?= “ \ …

  ${PACKAGECONFIG_EXAMPLES} \

”

4. to build the agl-image-ivi use the following command bitbake agl-image-ivi

5. run qt examples

to run a qt example you have to use a command like:

./analogclock -platform wayland-egl

where you have also have to pass the platform to be used

check platforms available ls /usr/lib/qt5/plugins/platforms/ ————————————————————————————————————— 6. known issues 6.1 with the first integration qtwebkit example applications do crash with seg fault. this seems to be a problem in qtwebkit!! to be investigated later!! ==== Maintainer(s) ==== ^ Name ^ Email ^ Area of Interest ^ | | | None | ==== Contributors ==== ^ Name ^ Email ^ Area of Interest ^ | | | None |
