Hello all! I got a problem with mobile extension. Here is my conf :
i downloaded QT Nokia SDK (offline version), installed it, tested with small simple application in emulator - everything work's fine. Now i downloaded and installed mobile extension from here http://wiki.forum.nokia.com/index.php/Mobile_Extensions and try to compile project with Telephony. I edited the .pro file of example , and i got an undefined error :

  2. Configuration unchanged, skipping qmake step.

  25. Error while building project TelephonyEx (target: Qt Simulator)
  26. When executing build step 'Make'

That is the problem? debug and release version error's are same..

After that ..
I uninstalled all Qt stuff, cleaned registry for qt and symbian..
Reinstalled :
1. Carbide + ActivePerl + Symbian S60 SDK + CSL;
2. Setuped Nokia QT SDK (full)
3. Setuped Mobile Extensions (like said in wiki)
and projects still wont compile... In wiki said what :
# Simpler usage:

* "system include" directory containing all public headers added
* Only LIBS += xq* is needed in .pro files
But i tryed to do that
#-------------------------------------------------
#
# Project created by QtCreator 2010-06-09T14:02:42
#
#-------------------------------------------------

QT += core gui

TARGET = QXTest
TEMPLATE = app
LIBS += xqtelephony
SOURCES += main.cpp\
widget.cpp
INCLUDEPATH += D:\storage\programming\QtSymbian\MEP3\extensions\i nclude
HEADERS += widget.h

FORMS += widget.ui
And nothing.. just error :
:: error: xqtelephony: No such file or directory
What i'am doing wrong?
