Well I trying to build the folder the lib on the folder "/buildlib" but I get some errors:

I can't find to "/src/corelib/"... Anyone is using the QExtSerialPort on Windows and Linux?
For linux is working everthing fine.

Hi, I notice that the message you provided says:

@
In file included from ..\src\qextserialport_win.cpp:44:
c:\QtSDK\Desktop\Qt\4.8.0\mingw\include/QtCore/private/qwineventnotifier_p.h:1:61: error: ../../../src/corelib/kernel/qwineventnotifier_p.h: No such file or directory
@

And if I'm right, this should be a bug of QtSDK. The contents of
@
c:\QtSDK\Desktop\Qt\4.8.0\mingw\include/QtCore/private/qwineventnotifier_p.h
@
is wrong!

IMO, there are several workarounds can be used.

If Qt's source code can be found in your hardware, fix the contents of this broken file. For example, change to

#include "c:\QtSDK\QtSources\4.8.0/src/corelib/kernel/qwineventnotifier_p.h"

or you can simply replace the file "include/QtCore/private/qwineventnotifier_p.h" with "src/corelib/kernel/qwineventnotifier_p.h"

If Qt's source code does not exist in your hardware, you can download this file from http://qt.gitorious.org/qt/qt/blobs/4.8/src/corelib/kernel/qwineventnotifier_p.h

then put it to $QTDIR/include/QtCore/private/qwineventnotifier_p.h

Remove the broken file

$QTDIR/include/QtCore/private/qwineventnotifier_p.h

then QextSerialPort will auto select qextwineventnotifier_p.h

Hi dcbasso,

It looks rather strange. In fact, moc_qextserialport.cpp is not a compile unit, which can be thought as a header file, so it should not be compiled independently.

If you have read the source code of qextserialport.cpp, you can found following line
@
#include "moc_qextserialport.cpp"
@

So the problem is, why the compiler want to compile it :-)

I resolve this problem...
Know I have this problem:

:-1: error: cannot find -lqextserialport-1.2d

Just on Windows!!!

dcbasso

Resolved!

mlong

bq. Resolved!

You might make a note of what the resolution was, in case someone else reads the thread in the future and has the same problem.

dcbasso

Solution: Compile the project on folder: "qextserialport/buildlib".

Someone help!!! I got same problem

Upon compiling i got the FF error
