Demos and examples problem
‘Demos and Examples’ problem
Hi,
Qt is something new for me, but I like power it has I have created one project for school but I want more I can’t figure out why examples don’t work:/ I have installed Qt SDK on mac and linux and I have these same problems on mac and linux with these same examples.
I try tu run ‘Bluetooth Scanner Example’ and these are errors:
error: qmobilityglobal.h: No such file or directory
error: qbluetoothlocaldevice.h: No such file or directory
error: expected constructor, destructor, or type conversion before ‘class’
error: ‘QTM_END_NAMESPACE’ does not name a type
error: ‘DeviceDiscoveryDialog’ was not declared in this scope
error: expected `;’ before ‘d’
error: ‘d’ was not declared in this scope
I am sure that I have to configure something to work properly.
I hope U help me

you should perhaps look into this right here:
http://doc.qt.nokia.com/qtmobility/btscanner.html
I presume it is your example?
There is no such file as: “qbluetoothlocaldevice.h” … sooo why is it included somewhere in your project? ;)
I would strongly advice you (this is what I do when my examples don’t work)
Just make a new project, get the code from the link above and just copy+paste.
Afterwards its normally fine.
have a nice day.
Ok, now after trying this myself… it simply does not work :D
Which brings us to the question, where are the missing libraries…
They are probably in (as stated in .pro file:)
INCLUDEPATH += ../../src/connectivity/bluetooth
DEPENDPATH += ../../src/connectivity/bluetooth
well I don’t have this “connectivity” BUT you should have a closer look at the auto updater of Qt Creator, perhaps you will be lucky :)
cheers mate.

there is,
under device.cpp. it’s one of a headers.
I believe that on this forum must be at least one person who develop bluetooth application and know how to set up Qt to run examples.
I think that problem is because compiler doesn’t know where are libraries. I also, don’t have this paths:
INCLUDEPATH += ../../src/connectivity/bluetooth DEPENDPATH += ../../src/connectivity/bluetooth
i found this path in file “qt-mobility-opensource-src-1.2.0.tar.gz”, but why install it if qtmobility is part of Qt SDK? Ignoring this fact, I have tried install qmobility from open source but there are some errors:/
I also did some experiment:
‘Bluetooth scanner example’ is desktop app, but I add simulator and run and build for simulator. And it works-but not properly:/ scan button is not active:/
now ,because it’s my 12 attempt I also confused about what should I install:/ I reinstall Xcode and I thought after downloading Qt SDK everything will be fine. I have found these files:
http://get.qt.nokia.com/qt/source/qt-mac-opensource-4.8.0.dmg
http://get.qt.nokia.com/qt/source/qt-mac-opensource-4.8.0-debug-libs.dmg ,I am very confused what to do:/ I need instruction what install and in what order.

Ok, first of all, I stated… the FILE is missing. The header is declared, yes but that is the error.
I searched my libraries and you should too and there are no “connectivity” libraries, sooo you should probably update your Qt application and get those libraries.
And I Just installed one package for mac back in the days sooo…. why do you need those two? :)
