QtSerialPort windows static link

pou_cz

Hi,
I use static build Qt4.8 on windows XP. Now I need use QtSerialPort library in my program. So I downloaded this library a compilated it. Every thing seems good (no error).
So I create new Project with this library, compiling is ok, but linker take me a lot of error. But I included library Qserialport.a to linker.
I added to serial_port.pro this lines:
@
CONFIG += serialport
LIBS +=-lQtSerialPort
@

but linker take this error:
@

Thank for answer!

You can statically linked by other way:

Comment in "qserialportglobal.h" for macro Q_DECL_IMPORT

@
#ifndef QT_STATIC

if defined(QT_BUILD_SERIALPORT_LIB)

define Q_SERIALPORT_EXPORT // Q_DECL_EXPORT

else

define Q_SERIALPORT_EXPORT // Q_DECL_IMPORT

endif

#else

define Q_SERIALPORT_EXPORT

#endif
@

Add direcrtly "serialport-lib.pri" to your project file *.pro:

@
include(<patch/to/pri>/serialport-lib.pri)
@

Thank you for answer!
Ok i comment this macro and add serialport-lib.pri to my project, now it send this error:
@
serialport-lib.pri:44:6: error: invalid preprocessing directive #MMP_RULES
serialport-lib.pri:52:7: error: invalid preprocessing directive #FIXME
serialport-lib.pri:53:6: error: invalid preprocessing directive #INCLUDEPATH

serialport-lib.pri:1:1: error: 'INCLUDEPATH' does not name a type
serialport-lib.pri:12:1: error: 'PUBLIC_HEADERS' does not name a type

Thank for answer! Jan Opravil

Hi,
Looks like you included serialport-lib.pri in a header, that's wrong, you have to include it in your project pro file.

UPD:

Need comment only for Q_DECL_IMPORT macro in “qserialportglobal.h”:
@
...

else

define Q_SERIALPORT_EXPORT //Q_DECL_IMPORT

endif

...
@

Need to fix some compilation errors like:

bq. E:\git\ng\123\qtserialport\src\serialport\qserialport.h:48: error: QtSerialPort/qserialportglobal.h: No such file or directory

Just rename includes from:

@
#include <QtSerialPort/qserialportglobal.h>
@

to

@
#include <qserialportglobal.h>
@

and so forth...

PS: This library is designed as a dynamic. Nobody checked and nobody build it as statically. So any problems related with the static building and linking - please resolve yourself.

It still not work for me…(some compiler error)
But thank!! and i accept this:
“So any problems related with the static building and linking – please resolve yourself.”
Now i link this library dynamic and it work.

@SGaist How to configure Qserialport static to Qt4.8 in ubuntu12.04

Hi and welcome to devnet,

Unless you really need it as a separated module, do as @kuzulis suggested: include the serialport-lib.pri file in your .pro file
