Regarding customized image with Qt embedded support.

Regarding customized image with Qt embedded support.

[Abhishek Sharma]

Hello all,

I am building an image for mini2440 which should support Qt embedded
applications. I even made a test recipe of a simple Qt embedded app(namely
"qtehelloworld") and then I wrote the image(namely qtehelloworld-image) as
such:

IMAGE_INSTALL = "qtehelloworld"
IMAGE_BASENAME = "qtehelloworld"
IMAGE_LINGUAS = ""
IMAGE_LOGIN_MANAGER = ""
IMAGE_INIT_MANAGER = ""
IMAGE_INITSCRIPTS = ""
IMAGE_DEV_MANAGER = ""
RDEPENDS = "qte"
DEPENDS = "task-base"
require base-image.bb
inherit image

here qtehelloworld as I mentioned earlier is a simple/sample qte app. Before
deploying to mini2440 I am testing the image for qemu by setting the conf to
MACHINE="qemuarm". But when I run the image, I am unable to find the
"qtehelloworld" app inside the image(to run the app). Kindly tell me, why is
such a thing happening.

Thank You.

Also even if I cannot "make" the qte application to be directly into the
image, then i could atleast do this, that I can create a minimalistic kind
of image(base-image) which has qte libraries but i don't know as to how
should i do it. Kindly help..

So here you add it to IMAGE_INSTALL...

[..]

> require base-image.bb

And here you let base-image remove it from IMAGE_INSTALL again. Move the
require statement to the top of your images and try again.

Thanks for the previous response. I did as suggested, but now the image
built gives this sort of an error.
kernel panic - not syncing: No init found. Try passing init= option to
kernel

I don't have a clue as to why this is happening, do i need to set something
in my image-recipe or the app-recipe???
Kindly help!!!

Thanks

Ehm, you specified that it shouldn't contain an init with:

IMAGE_INIT_MANAGER = ""
IMAGE_INITSCRIPTS = ""

Why did you put those vars in if you to want /sbin/init to be there?!?!?

It was silly of me to put INIT_SCRIPTS = "" without actually knowing about them.
Now I have changed the image file and it looks like:
require base-image.bb
IMAGE_INSTALL = "qtehelloworld"
IMAGE_BASENAME = "qtehelloworld"
RDEPENDS = "qte"
inherit image

Yet when I buils the image the same init error occurs. I am confused
as to why is that happening?? Since I have used [required
base-image.bb] so init parameters must be set automatically or do i
need to set them manually??

you need += here, else you replace the content of IMAGE_INSTALL 
inherited from base-image by only your app !

I am finished making the image which has a qtehelloworld program "installed"
in it. But the moment I run <qtehelloworld -qws> in the qemu machine i get
the error
QFontDatabase: Cannot find font directory /usr/lib/fonts.

I googled the error and in most of the cases it was shown that while
"configuring" qte the prefix variable was not properly set. What step should
i take next?? Do i need to change any recipe of qt embedded or is this some
different problem.

Please Help.

add "qt4-embedded-fonts" to your IMAGE_INSTALL

Thanks for the solution Eric. I was also facing problems regarding tslib,
which u answered on the irc. I did
IMAGE_INSTALL += "qt4-embedded-plugin-mousedriver-tslib"

but still when I am running the qtehelloworld app on the created image in
qemu, everything is being "displayed" fine but the mouse pointer is not
moving when I try it to, in other words the touch screen ain't working with
the image while it works when i try to run a preconfigured opie-image.
Please help.

Thank You.

QWS_MOUSE_PROTO=tslib:/dev/input/touchscreen0 qt-app -qws

About the /dev node, there is no such device as /dev/input/touchscreen0, is
it because i am only doing a base-image kind of install???
i set the environment variable which was specified, but no progress.

If you use udev, it will get created for you.

Thanks all, the touchscreen device was /dev/event1 and the moment I did ->
export QWS_MOUSE_PROTO="Tslib:/dev/event1" and ran the app, it got going.
I am very grateful to you all for the help.

Hi all.
This was my_customized_image.bb :

   1. require base-image.bb
   2. IMAGE_INSTALL += "qtehelloworld"
   3. IMAGE_INSTALL += "qt4-embedded-fonts"
   4. IMAGE_INSTALL += "qt4-embedded-plugin-mousedriver-tslib"
   5. IMAGE_BASENAME = "qtehelloworld"
   6. RDEPENDS += "qte"
   7. inherit image


Now this one has a size of 64 Mb. I used base-image as a requirement to
install the basic utilities and since I had to run a qt embedded based app
on the machine I also had to include the qte runtime dependencies. Is there
any way so that the image size can be reduced??

Thanks.

Regarding customized image with Qt embedded support.

[Abhishek Sharma]

Hello all,

I am building an image for mini2440 which should support Qt embedded
applications. I even made a test recipe of a simple Qt embedded app(namely
"qtehelloworld") and then I wrote the image(namely qtehelloworld-image) as
such:

IMAGE_INSTALL = "qtehelloworld"
IMAGE_BASENAME = "qtehelloworld"
IMAGE_LINGUAS = ""
IMAGE_LOGIN_MANAGER = ""
IMAGE_INIT_MANAGER = ""
IMAGE_INITSCRIPTS = ""
IMAGE_DEV_MANAGER = ""
RDEPENDS = "qte"
DEPENDS = "task-base"
require base-image.bb
inherit image

here qtehelloworld as I mentioned earlier is a simple/sample qte app. Before
deploying to mini2440 I am testing the image for qemu by setting the conf to
MACHINE="qemuarm". But when I run the image, I am unable to find the
"qtehelloworld" app inside the image(to run the app). Kindly tell me, why is
such a thing happening.

Thank You.
