Hi,
This error "'Component QtMobility missing. Continue anyway?" comes from
dependency you have in your package files. check x_template.pkg. If pkg is
wrong, then qtmobility.prf file (located in
c:\qt\4.6.3\mkspecs\features\mobility.prf) might not be updated from the latest
qtmobility build. It has got (or something like) these dependency lines which
are taken into use when you use config=MOBILITY option in your pro file.
# Add dependency to QtMobility package to all projects besides QtMobility
package itself.
# Mobility libs have UID3 0x2002AC89
# self-signed Mobility libs have UID3 0xE002AC89
symbian:contains(CONFIG, mobility):!contains(TARGET.UID3,
0x2002AC89):!contains(TARGET.UID3, 0xE002AC89) {
mobility_default_deployment.pkg_prerules += \
"; Default dependency to QtMobility libraries" \
"(0x2002AC89), 1, 1, 0, {\"QtMobility\"}"
DEPLOYMENT += mobility_default_deployment
For symbian multimedia camera parts to work you will need:
either qtmobility.sis from src\s60installs\ (after you you have compiled and
run make sis)
or
QtMultimediaKit.sis (api, from src/multimedia) + qtmultimediakit_ecamengine.sis
(api backend, from plugins\multimedia\symbian\ecam).
But I think dlls should be in place though. In emulator it can crash for
various reasons one is that emulator doesn't support camera very well. You can
put a break point in S60CameraService constructor and see if it loads the
backend at all.
In Hw you can check these (in emulator there might not be any devices...):
There are static methods inQCamera class that should return reasonable values
(2 devices, and some description):
static QList<QByteArray> availableDevices();
static QString deviceDescription(const QByteArray &device);

Subject: RE: [Qt-mobility-feedback] Do there exist a prebuilt sis file for
QtMobility 1.1 TP?
Have now fetched the head/master revision (from the
http://qt.gitorious.org/qt-mobility/qt-mobility/trees/HEAD though).
It configures and compiles fine (have only tried with "-modules multimedia",
but all seems to be fine.)
Until I want to run the camera example that is. ;-)
In the emulator (in Carbide), it boots, and load, and then panics.
On the device it still reports 'Component QtMobility missing. Continue
anyway?'. I have done the 'make sis' step, and have installed QtMobility.sis
file on the device. And if I try to reinstall it, it says it is already
installed. My best guess would be that QtMobility uses another ID to install
itself than the id the other packages look for. But when I investigate the pkg
files it seems to be the same Id all over (0x2002AC89).
If I continue and install it, the camera example panics on startup and never
gets started.
So it seemed better, but I must still be missing something.
Trying to install qtmultimediakit_ecamengine.sis (or a signed sisx), once again
gives me a warning about QtMobility not installed, and during install I get an
update error. Looking at the src\s60installs\QtMobility_template.pkg, it seems
like the ecamengine should be included automatically.
But clearly I'm missing something.
Any good ideas out there?
/Anders

Hi,
Just realized that symbian Camera backend wasn't available in qtmobility 1.1
TP. So I am not amazed that id doesn't work :-). Backend is located in
plugins\multimedia\symbian\ecam
For camera to work you will need newer code. You have to get it from gitorious
via git and compile that again. This isn't released just yet so there might be
some bugs still, but if there are bugs, please report those also.
Magic command for getting the code..
"git clone git://gitorious.org/qt-mobility/qt-mobility.git"

The rest of the mail follows here - damn keyboard shortcuts...
Hi all
Now the week are about to end, and I'm still struggling getting QtMobility 1.1
TP running on my device.
So my question now is... Can anyone in the community send me a working sis file
able to install QtMobility 1.1 TP on a device?
Below is a resume of where I am standing now.
To sum up, my situation is this:
1. I have successfully installed Qt 4.7 RC, and QtMobility 1.1 TP on my
machine. QtMobility configured to only use Multimedia module.
2. I can compile the Camera Sample, and I can build my own small samples
using Multimedia module, and including Camera.
3. I can create sis files that run on phone (when not instantiating a
Camera object)
a. This sample compiles, and installs (With warning that QtMobility is
not installed - even though it is) and runs on my device:
#include "JustHello.h"
#include <qmessagebox.h>
#include <qcamera.h>
JustHello::JustHello(QWidget *parent)
: QMainWindow(parent)
{
ui.setupUi(this);
QMessageBox::information(this, "JustHello", "App
started");
// camera = new QCamera();
}
b. This sample compiles, installs (with warning that QtMobility is not
installed - even though it is), but panics at startup.
#include "JustHello.h"
#include <qmessagebox.h>
#include <qcamera.h>
JustHello::JustHello(QWidget *parent)
: QMainWindow(parent)
{
ui.setupUi(this);
QMessageBox::information(this, "JustHello", "App
started");
camera = new QCamera();
}
My QtMobility.sis file installs, but subsequently installs of applications with
QtMobility 1.1 as prerequisite reports that QtMobility is not installed.
I really hope somebody can take 10 seconds of their time to send me their sis
file.. ;-)
Have a nice weekend
/Anders
