Help in building an ad-hoc qte image

Hi Paul,

thanks for your reply. 

>>
If I understand correctly in that you have more than one machine and you 
need 
gstreamer on ANOTHERBOARD and all other machines don't need it,
<<

let me rephrase for the sake of clearness. 
This part of recipe: 

RDEPENDS_${PN}-base_ANOTHERBOARD  = " \
        libqt-embeddedphonon4 \
        qt4-embedded-plugin-phonon-backend-gstreamer \
        "

has the ultimate goal of adding phonon + gstreamer backend
for ANOTHERBOARD only to the rootfs.
It appears ok. We normally do not get indeed phonon + gstreamer backend.

The issue is that we get contents of 
meta\recipes-multimedia\gstreamer\gstreamer_0.10.36.bb
(see original post for listing) in the rootfs and do not get what pull 
them in.

We see that gstreamer is set as DEPENDS for qte (rif. qt4.inc) thus 
correctly built together
with qt4-embedded.

But our "task-qt4e-xyz" recipe defines qt4-embedded as DEPENDS instead of 
RDEPENDS.

Shouldn't be this enough to ask bitbake for building qte but not install
other than what specified in RDEPENDS to the rootfs?

Thanks in advance for your help. Regards.

Ah, right, now I understand the question. So you've asked for task-qt4e-xyz-
base to be installed, and task-qt4e-xyz-base for ANOTHERBOARD RDEPENDS upon
qt4-embedded-plugin-phonon-backend-gstreamer. The "missing link" is that in 
do_package we have some code to analyse shared libraries (.so) that are going 
into a package in order to detect which other shared libraries they need, and 
if any are found we look to see which package provides them and automatically 
add that package to RDEPENDS. Thus we look at the .so files in qt4-embedded-
plugin-phonon-backend-gstreamer and determine from them that gstreamer is 
required, thus gstreamer (along with libgstaudio and libgstvideo) is added to 
RDEPENDS. See classes/package.bbclass if you want to see the code for this 
(look for shlibdeps).

Note that sometimes this highlights problems with package granularity - I 
don't know enough about gstreamer to know if any of the files currently in the 
"gstreamer" package could actually be separated out if they aren't desired in 
some installations. Occasionally as a result we do split packages further to 
avoid unnecessary files being installed for all situations.

Cheers,
Paul

maybe you meant

>> RDEPENDS_${PN}-base_append_ANOTHERBOARD  = " \

Finally, it looks like you could easily workaround your problem by
defining a specific recipe for ANOTHERBOARD.

Regards

Andrea

P.S.: try bitbake -g XYZ  or   bitbake -g -u depexp XYZ  to quickly
inspect dependencies

Ah yes, well spotted.

Except I don't think you will find this includes automatic runtime dependencies 
such as the shlibdeps I described previously.

Hi Paul and Andrea

thanks for your reply. I did some testing (including splitting task recipe 
per each target and including PACKAGE_ARCH = "${MACHINE_ARCH}") 
but with no success.

Even removing this from task recipes: 

RDEPENDS_${PN}-base_append_ANOTHERBOARD  = " \
        libqt-embeddedphonon4 \
        qt4-embedded-plugin-phonon-backend-gstreamer \
        "

pulls in gstreamer. I guess some other qt lib (other than phonon & 
gstreamer plugin) do introduce some shlibdeps to gstreamer
as Paul indicated.

thanks for your help. Regards.

Help in building an ad-hoc qte image

[giovanni.pavoni]

[-- Attachment #1: Type: text/plain, Size: 7247 bytes --]

Dear Sirs,

this is to ask for help in building an ad-hoc qte image. My image bb sets
as DEPENDS a custom "task-qt4e-xyz" task. Where task-qt4e-xyz.bb looks as 
follow:

//---------------------//

DESCRIPTION = "QT4 embedded xyz base image feed"
PR = "r1"
LICENSE = "MIT"

LIC_FILES_CHKSUM = "file://$
{COREBASE}/LICENSE;md5=3f40d7994397109285ec7b81fdeb3b58 \
                    file://$
{COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420"

PR = "r3"

inherit task

TOUCH = ' ${@base_contains("MACHINE_FEATURES", "touchscreen", "tslib 
tslib-calibrate", "",d)}'

PACKAGES += " \
        ${PN}-base \
        "
DEPENDS = "qt4-embedded"

RDEPENDS_${PN}-base = " \
        qt4-embedded-conf \
        libqt-embeddedcore4 \
        libqt-embeddeddbus4 \
        libqt-embeddedgui4 \
        libqt-embeddedmultimedia4 \
        libqt-embeddednetwork4 \
        libqt-embeddedscript4 \
        libqt-embeddedscripttools4 \
        libqt-embeddedsvg4 \
        libqt-embeddedxml4 \
        qt4-embedded-fonts-ttf-dejavu \
        qt4-embedded-fonts-ttf-vera \
        qt4-embedded-plugin-iconengine-svgicon \

        qt4-embedded-plugin-imageformat-ico \
        qt4-embedded-plugin-imageformat-jpeg \
        qt4-embedded-plugin-imageformat-mng \
        qt4-embedded-plugin-imageformat-svg \
        qt4-embedded-plugin-imageformat-tiff \
        qt4-embedded-plugin-mousedriver-tslib \
        qt4-embedded-plugin-script-dbus \
        ${TOUCH} \
        "
 
RDEPENDS_${PN}-base_ANOTHERBOARD  = " \
        libqt-embeddedphonon4 \
        qt4-embedded-plugin-phonon-backend-gstreamer \
        "
 
RRECOMMENDS_${PN}-base = " \
        libqt-embeddedwebkit4 \
        libqt-embeddedxmlpatterns4 \
        "
//---------------------//

The problem: I am getting in my image gstreamer contents (see below for 
files in my rootfs)
but I unable to trace what gets it in. I need to build gstreamer to add to 
ANOTHERBOARD 
(thus would expect to add it to RDEPENDS_${PN}-base_ANOTHERBOARD) but do 
not need it by default.

Anyone can give an hint? Thanks in advance for your help.

//---------------------//

If I understand correctly in that you have more than one machine and you need 
gstreamer on ANOTHERBOARD and all other machines don't need it, I think the 
problem here may be that the task package is not being built as machine-
specific; thus if task-qt4e-xyz is built for ANOTHERBOARD first then it will 
bring in qt4-embedded-plugin-phonon-backend-gstreamer which pulls in 
gstreamer. You may find that the problem goes away if you add this to the task 
recipe:

PACKAGE_ARCH = "${MACHINE_ARCH}"

It's worth noting however that you don't have to add qt4-embedded-plugin-
phonon-backend-gstreamer here at all in order to have it built - the qt4 
recipes always build it; so if you were adding it here just to make it build 
and you don't need it installed by default, none of this is necessary at all.

Cheers,
Paul
