Someone should update QQrDecoder app to use QCamera from QtMobility, but you can still make a device build work with minimal effort on QtSDK 1.1.
First, download a staticlib version of the camera wrapper library that QQrDecoder depends on. You can extract them on top of Qt SDK, follow the instructions in the readme.txt file.
Then, modify the symbian-specific part of the .pro file as follows:
Code:
symbian {
TARGET.UID3 = 0xEF2CE79D
HEADERS += QCameraControllerWidget.h
SOURCES += QCameraControllerWidget.cpp
LIBS += -leuser \
-lapparc \
-lcone \
-leikcore \
-lavkon \
-lefsrv \
-lestor \
-lfbscli \
-lbitgdi \
-leikcoctl \
-lbafl \
-lecam \
-lecamadvsettings \
-lcamerawrapper_s.lib \
-lcamautofocus_s.lib
TARGET.CAPABILITY = UserEnvironment
}
Then, do a clean rebuild of the project.

You don't actually need them, they can be removed. See the modified .pro file above.
