[Solved] Adding QtSerialPort to 4.6.3

McLion

I read the wiki over and over. The explanations are not very detailed.
I'll try again with your instructions and post back.

OK, I am now trying to simply add it to my local Qt installation and build it under windows. Let's move it to Linux later.

I copied to "C:\QtSDK\Desktop\Qt\4.6.3\src\qt-qtserialport"
I opened serialport.pro
Did Build settings
Replaced QElapsedTimer with QTime
changed include path in qserialportinfo_win.cpp #include "C:\QtSDK\mingw\include\ddk\cfgmgr32.h"
Changed include path in qserialport_win.cpp to #include "qt4support/include/QtCore/qwineventnotifier.h"
and now getting

@mingw32-make.exe[1]: Leaving directory `C:/QtSDK/Desktop/Qt/4.6.3/src/qt-qtserialport/src/serialport-build-desktop-Qt_4_6_3_for_Desktop_-_MinGW_Release'
..\serialport\qserialportinfo_win.cpp: In static member function 'static QList<QSerialPortInfo> QSerialPortInfo::availablePorts()':
..\serialport\qserialportinfo_win.cpp:258: error: 'find_if' is not a member of 'std'
..\serialport\qserialportinfo_win.cpp:307: error: 'find_if' is not a member of 'std'@

Added #include <algorithm> .... and moving further

I think I am missing this step because the libraries are built but not installed:

add a new make “Build Step” and write to the “Make arguments” the install target

... I am not really sure how to do this ?!?

McLion

... found it:

Switch to Projects Mode: press Ctrl+5.
On Build Settings tab under Build Steps click on Add Build Step.
Choose Make from the menu.
Write install into Make arguments: text input box.

.. libraries are installed in local 4.6.3 on windows. :)
... moving forward ...

Including into a new empty project does not work, returning:

It installed .dll to /bin, .h to /include/QtSerialPort, .a, lib.dll and .prl to /lib. So far, this seems ok to me but it still returns the errors above.

Any idea?

McLion

Found it. If its done like in the wiki with adding
@CONFIG += serialport@

to the pro, it does not work.
I had to manually copy the prf from the sources and add:

@include(C:\QtSDK\Desktop\Qt\4.6.3\lib\serialport.prf)@

to the pro file (for what ever this file is for ?!?)
Finally, it runs under windows ... now I'll try to port it to my eLinux environment .. which will be trickier, I assume.

The serialport.prf should be in \mkspecs\features\ in your Qt place. Then CONFIG += serialport should be work correctly.

McLion

Perfect! Thanks a lot.
Now .. moving to Linux ... I'll keep this thread updated

McLion

Needed some changes to the sources. However, one line of code still bugs me:

@const qint64 age = QFileInfo(fileName).lastModified().msecsTo(QDateTime::currentDateTime());@

msecsTo is not available in QDateTime in 4.6.3.
Any idea?

kuzulis

You can do not use QLockFile.. Just exclude this module/code from compilation (e.g. comments out some places and so on).

McLion

Thanks. Decided to replace
@const qint64 age = QFileInfo(fileName).lastModified().msecsTo(QDateTime::currentDateTime());
return staleLockTime > 0 && age > staleLockTime;
@
with
@return staleLockTime > 0 && (QDateTime::currentDateTime() > QFileInfo(fileName).lastModified().addMSecs(staleLockTime));@

It works! :)
Just compiled for my eLinux and used the basics from the wiki reading out port names. Going to replace qextserialport with QtSerialPort now and hope it helpes in solving my communication issue.

Thanks for your support and patience.

Did the same, althought serialport.prf is in mkspec/features directory and I've added CONFIG += serialport in *.pro file. Works as intended
