I ran into this as well after using a bbappend to disable a number of
Qt features, including the building of demos that get staged in the
aforementioned path.  In my case, that qtopia directory (and any
subdirectories) wound up either being empty or containing files that
were unnecessary for my build.

My quick and dirty solution was to just to add a install_append()
containing a 'rm -rf ${D}${datadir}/qtopia' in my bbappend. (Be sure
you don't have anything important in there!) I'd be curious to hear if
there's a better approach to this as well...

Oops...just wanted to note the typo in my above response -- I'm not at
a machine where I have access to my recipes.

That should be a do_install_append(), not install_append().  I'd also
double check the qtopia path, as I wrote that from memory, which may
not be reliable. ;)

Apologies,
Jon

I tried the same but again ended up with error. As of now i am removing all
unwanted things from rootfs by making changes in image_types.bbclass. I am
sure this is not the correct way, any ideas are appreciated..

Thanks

Can I ask both of you exactly how you are getting Qt installed into the image?

I'm not doing anything too unusual for "installing" Qt. My recipes for
my Qt application simply inherit qt4e, and list qt4-embedded in
DEPENDS.

The only place where I deviated a bit from the norm is that I use a
qt4-embedded_4.8.3.bbappend to set up QT_CONFIG_FLAGS exactly as I
want them, and to rm ${D}/usr/bin/qtopia. Below's my bbappend. I'd be
interested to hear if there's a better way to clean out unneeded
directories from a rootfs (in my case ${D}/usr/bin/qtopia).

DEPENDS = "qt4-tools-native freetype jpeg libpng zlib"

# Override provided recipe and configure Qt4 to...
# - Disable irrelevant functionality and output
# - Disable SQL Plugins
# - Disable unused input/ouput
# - Have keyboard input and mouse input via /dev/input/mice
# - Have Linux framebuffer support
# - Use QML (so we need the declarative engine)
#
# Note, some of these might be extraneous, and this is a work in progress.
# (You've been warned!)

"inherit qt4e" is enough, no need to add qt4-embedded to DEPENDS.

strange, demos and examples are packaged in ${QT_BASE_NAME}-demos and
${QT_BASE_NAME}-examples packages so if you find these directories on
your target, that means you requested qt4-embedded-demos and
qt4-embedded-examples to be installed in your image.

Are you installing packagegroup-core-qt4e in your image like in 
qt4e-demo-image ? If yes, that's where you pull demos & examples.

To get a minimal image, you could simply have :
IMAGE_INSTALL += "\
	${CORE_IMAGE_BASE_INSTALL} \
	you_qt_app \
	some qt4-embedded-fonts or qt4-embedded-plugin you may need
	(check packagegroup-core-qt4e.bb for the exact names) \
	"
inherit core-image

The Qt libraries your application is linked with will be automatically
installed and you won't get extra unwanted packages in your image.

Best regards,
Eric

Thanks! This makes sense, as I see this dependency is established in
the first few lines of qt4e.bbclass.

My IMAGE_INSTALL looks very similar to what you've shown there, which
I based upon what I saw in core-image-minimal. I see that I still have
a task-core-boot lying around, so I need to change that a
packagegroup-core-boot. (IIRC, packagegroup-core-boot PROVIDES
task-core-boot for the time being...)

IMAGE_INSTALL = "
  task-core-boot \
  my_qt_app \
  a_few_unrelated_recipes_that_don't_use_qt \
  ${ROOTFS_PKGMANAGE_BOOTSTRAP} \
  ${CORE_IMAGE_EXTRA_INSTALL} \
"

I checked the package list on a running system (opkg list | grep -i
qt). Here's all the installed Qt packages...no qt4-embedded-examples
as far as I see.

libqtcoree4 - 4.8.3-r50.0
libqtdeclarativee4 - 4.8.3-r50.0
libqtguie4 - 4.8.3-r50.0
libqtnetworke4 - 4.8.3-r50.0
libqtscripte4 - 4.8.3-r50.0
libqtsqle4 - 4.8.3-r50.0

Seems strange to me...any thoughts?

Thank you for your time and help!

strange, in a fresh build of danny /usr/share/qtopia is only present in
the following packages :

./qt4-embedded-translation-linguist/usr/share/qtopia
./qt4-embedded-translation-qt/usr/share/qtopia
./qt4-embedded-translation-qvfb/usr/share/qtopia

can you check in your workdir in packages-split which package includes
this directory ?

Eric,

Sorry for the delay. I did check my packages-split and it was the same
as what you listed.

Since your email, I had removed my do_install_append() from my
qt4-embedded bbappend, blown away build/$MY_DIR/tmp and done a full
rebuild. I no longer see the qtopia directory in my images. Perhaps
this was a vestige of me experimenting with Qt early on?

I guess I'll call it a mystery solved for the time being, but will
touch back on the mailing list if I figure out what exactly caused
this to be populated in my filesystem. (Unless of course, there were
other items you'd like me to check.)

Thanks again,
Jon

Remove unwanted package from Qt

[Navani Srivastava]

[-- Attachment #1: Type: text/plain, Size: 403 bytes --]

Hi,

I am compiling Qt-4.8.0 with poky-denzil-7.0 for arm1136 architecture.



At the time of integrating qt-embedded with rootfs, I am getting qtopia
directory in usr/share path of rootfs.

I tried removing qtopia directory through qt recipe but ended in
compilation error. Please suggest any idea to remove qtopia from share
directory.



Thanks and Regards

"qtopia" is just the name of the directory that gets used for Qt Embedded (see 
the QT_DIR_NAME setting in meta/classes/qt4e.bbclass) - are there actually any 
files in that directory you don't want or is it just the directory name that 
concerns you?

Paul
