missing rrsensorapi.h for gathering sensor data from N97 Nokia device

I am quite new with symbian and c++. I try to use sensor on N97 device. I got error that rrsensorapi.h is not found. I have check through epoc folder it not there either. In this case, how can I find rrsensorapi?

I have sensor.pri file like this

INCLUDEPATH += $$APP_LAYER_SYSTEMINCLUDE

HEADERS += xqsensor.h \
    xqaccsensor.h \
    xqdeviceorientation.h \
    xqdeviceorientation_p.h

SOURCES += xqsensor.cpp \
    xqaccsensor.cpp \
    xqdeviceorientation.cpp \
    xqdeviceorientation_p.cpp

  exists($${EPOCROOT}epoc32/release/winscw/udeb/RRSensorApi.lib)| \
    exists($${EPOCROOT}epoc32/release/armv5/lib/RRSensorApi.lib) {
        message( "Building for Sensor plugin" )

    DEPENDPATH += .\plugin

    HEAD开发者_StackOverflow社区ERS += xqsensor_p.h \
        xqaccsensor_p.h

    SOURCES += xqsensor_p.cpp \
        xqaccsensor_p.cpp

    symbian:LIBS += -lRRSensorApi
    } else {
        message("Warning: Sensor API not found!")

    }

As quoted on the Forum Nokia Discussions website, the RRSensorAPI works only with SOME S60 3rd Edition FP1 devices... Info here.

The API's for sensors on S60v5 have been changed... To solve your question of using sensors with the N97 (S60 5th Edition), refer to this wiki document on Forum Nokia.

Hope this helps...
