我是symbian和c ++的新手。我尝试在N97设备上使用传感器。我收到rrsensorapi.h未找到的错误。我通过epoc文件夹检查它也不存在。在这种情况下，我怎样才能找到rrsensorapi？
我有像这样的sensor.pri文件
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) {

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