Qt QextSerialPort static lib
How to create static library QextSerialPort for Windows platform for use with Qt 4.8.5
I don't understand how to change the .pro or .pri files for this. (The .prf file keeps recovering).
So, I tried to modify the resulting .vcproj file to make a static build, and removed some of the definitions, but I still get warnings like:
qextserialport.lib (qextserialport.obj): warning LNK4006: "public: __thiscall QextSerialPort :: QextSerialPort (class QString const &, enum QextSerialPort :: QueryMode, class QObjectAB *)" (?? 0Qext@QAerialPort @String 0 @PAVQObject @@@ Z) is already defined in qextserialportd1.lib (qextserialportd1.dll); the second definition is ignored
and get "System error: the program cannot start because qextserailportd1.dll is missing from your computer". Which of course is true because I am trying to do a static build using .lib
So how do you do a static build correctly?

There is no need to create a static QextSerialPort library. You can just use the source code in your application. Just add the file .pri
to your file .pro
:
include(Path/To/qextserialport.pri)
Or copy the QextSerialPort source code from directory src
to application directory and add the following line to your project file:
include(qextserialport.pri)
Now you can include the header file:
#include "qextserialport.h"
And use the library:
QextSerialPort * port = new QextSerialPort("COM1");
connect(port, SIGNAL(readyRead()), this, SLOT(onDataAvailable()));
port->open();
No need to link a library or place a DLL for deployment.

Thanks to Nejat for your answer. Very clear.
Also, for those following in my footsteps, this was a reading-guide case for me. Answer: https://code.google.com/p/qextserialport/wiki/QextSerialPort_1_2_RC
It just says to add CONFIG + = qesp_static
to the .pro file. This works too.
