Using QBluetooth library in Qt Creator

[PC-Man]

I like to use QBluetooth library for my project (Nokia 5800 app).

I did these steps - http://wiki.forum.nokia.com/index.ph...etooth_library -> Including the library -> Use the binaries :

1) I copied library files to epoc32 folder


2) I copied this block to my .pro file

symbian{
       INCLUDEPATH += /epoc32/include/QBluetooth
       LIBS += -lQBluetooth
 
       customrules.pkg_prerules  = \
	";QBluetooth" \
	"@\"$(EPOCROOT)Epoc32/InstallToDevice/QBluetooth_selfsigned.sisx\",(0xA003328D)"\
	" "	
 
	DEPLOYMENT += customrules
}

And I have problem:

If I use in code #include <QBluetooth>, Qt Creator show error: QBluetooth: No such file or directory...

(Sorry for my english)

First of all make sure that you are building the project at Phone Debug (or Release) configuration. Any other configuration (Qt Simulator for instance) will not do. This will fix the include problem.

Also in Qt Creator the following line:

"@\"$(EPOCROOT)Epoc32/InstallToDevice/QBluetooth_selfsigned.sisx\",(0xA003328D)"\

must be changed into

"@\"$$(EPOCROOT)Epoc32/InstallToDevice/QBluetooth_selfsigned.sisx\",(0xA003328D)"\

(we add one more '$')

Now you should be fine!

One more thing, to include the library write #include <QBluetooth.h>
The .h is needed.

Hello.
I've got a question: where exactly headers must be placed?
I have builded QBluetooth for Windows and writed to the .pro file of my program:

LIBS += -lQBluetooth -L$$(QTDIR)/QBluetooth/bin
INCLUDEPATH += ..\QBluetooth
HEADERS += ..\QBluetooth\QBluetooth.h

and got errors

In file included from ..\bluetooth-computer\main.cpp:2:

..\bluetooth-computer\/widget.h:6:24: error: QBluetooth.h: No such file or directory

..\bluetooth-computer\/widget.h:7:23: error: QBtDevice.h: No such file or directory

In file included from ..\bluetooth-computer\main.cpp:2:

..\bluetooth-computer\/widget.h:24: error: 'QBtDevice' was not declared in this scope

..\bluetooth-computer\/widget.h:24: error: template argument 1 is invalid

..\bluetooth-computer\/widget.h:28: error: 'QBtDevice' has not been declared

I tried to copy HEADERS and INCLUDEPATH from QBluetooth.pro and it did not help.

Well, I copied all QBluetooth .h files to the same directory as library file and errrors seems to disappear.
But after building is finished, I got

Starting E:\Qt\Projects\bluetooth-computer-build-desktop\debug\bluetooth-computer.exe...
The process could not be started!

Did anyone say that the QBluetooth library should work on desktop PC as well? Unless you have strong reasons to think that to be the case, I would suggest that you limit yourself to using it in Symbian targeted builds.

[colorfulFOOL]

It is written here.
And after several days of problems solving I got it working in Windows.

[ltomuta]

Nice. Apparently I stopped reading just before "... and Windows."
