I already copied libraries to the folder where my exe. file in (debug and release folder) but like I said before it gave an error. but I don't try last you said because I don't understan what should I do. Please I really need your help

See /examples and /test. And make by analogy.

Thank you so much for your help. :)

then I add qserialdevice_global.h to include folder. This time no error but after my application opened and when I clicked the button .exe stop running error showed up. Also in my application output, ...exited with code -1073741819 wrote.

To start the application you must copy the libraries to the application's executable file (easiest option).

Hi kuzulis,
thank you very much for share this lib ;)

I copied the dir include from mingw to compile until here.
Have any suggestion to compile it?

I don't need the windows support.ù
It is available a qserialdevice with only support for linux?

Best regards,

Krozac

Hmm, strange. The impression that qmake does not handle *. pri / *. pro files. Maybe the problem is that the Embedded?

Try to remove it from *. pri / *. pro files, everything related to ** _win.

I (and others) in such a PC with Linux is compiled without any problems.
I did not use Embedded ARM so I can not help you.

Hi Kuzulis,
Thank you very much.
I have to remove all lines with *win* from .pri and .pro AND delete all files named *win*.
Now I can compile test1.pro but when I try to compile guiapp2.pro I have this error:

Hi Krozac.

Oh, a lot of mistakes building... :)

I do not know where you have so many errors. Perhaps the reason is that you have a poorly installed or compiled by myself Qt-Embedded-arm. You first try to collect for their Qt-Embedded-arm any application of the examples of Qt (eg network, etc.).
And if you all get - that means the problem is QSerialDevice, but I can not help you solve it.

Hi Kuzulis,

It is missing some code from the *win* *mac* files that I delete all references and files?

Best regards

Nothing should be removed.

1. Reinstall the new Qt SDK (example, stable SDK for Windows):
http://get.qt.nokia.com/qtsdk/qt-sdk-win-opensource-2010.05.exe
2. Download stable QSerialDevice version 0.4.0 :
https://gitorious.org/qserialdevice/qserialdevice/archive-tarball/0.4.0
3. And build!

PS: In those errors (which you post it above) are analyzed myself, I do not know these errors.

Hello,

I am trying to use the QSerialDevice library, I've downloaded the files and I do the build with QtCreator and everything builds fine. Then I open the writer example but when I try to compile I get the following error:

error: cannot find -lqserialdeviced
error: collect2: ld returned 1 exit status

Do you know how can I fix it to be able to use the QSerialDevice?

Thank you very much and good work!

To compile the static library and examples need to open BuildExamples.pro.

Hi,

I tried it and the examples are working now, but I tried to write a simple test code from scratch and I can't make it work.

Do I need to copy the qserialdevice and qserialdeviceenumerator folders to my project in order to use the QSerialDevice.
I've included the abstractserial.h to my project but it won't compile.
I thought that since I build the BuildLibrary it would work on any other project.

What am I doing wrong?

Thanks for the help!

Do you have (at least) three ways:
1. You can in your project to use copies of the library folder (qserialdevice and qserialdeviceenumerator) and connect them to the project over (with) *. pri files.
(see examples \test\guiapp(guiapp2).
2. You can separately compile (default) static library with the aid of BuildLibrary.pro. For inclusion in the project you only need the header files (abstractserial.h, serialdeviceenumerator.h) and the file library (libqserialdevice(d).a).
3. Also similar to step 2. you can dynamically build the library and use it as in step 2. (ie, the library file will libqserialdevice (d). dll (so)).

--
For using p.2 and/or p.3 in your project file, you must specify:
- INCLUDEPATH += <the path to directory where are the header files>
- QMAKE_LIBDIR += <the path to directory where are the library file>
- LIBS += -l<name of library file>

see examples in /examples directory

I'm sorry but I can not understand what you mean exactly. I have only (.a) not (.dll) after build .pro file. What should I do next? Copy that file into my project folder?

I add what you write above to my project .pro file and add #include <abstractserial.h> but after build it gives me errors like ":: error: cannot find -llibqserialdeviced.a" and ":: error: collect2: ld returned 1 exit status" please help me

If you want to use the library as a dynamic that (for Windows):

1. You first need to compile it as dynamic.
Change /src/src.pro:
---
#CONFIG += staticlib
CONFIG += dll
---

2. Build liblary, use BuildLibrary.pro.
After this, you will be ready to Library,
example here: ../build/(debug/release)/qserialdevice(d).dll

3. Copy header files (abstractserial.h, serialdeviceenumerator.h), and library (qserialdevice(d).dll)
to your project directory, example:
---
/yourproject
|-/lib
| |->qserialdevice(d).dll
|-/includes
| |->abstractserial.h
| |->serialdeviceenumerator.h
|-/yoursrc
|->your *.cpp/*.h
|->your.pro
---

4. For compile your project - change your your.pro, example:
---
INCLUDEPATH += ../includes
QMAKE_LIBDIR += ../lib
LIBS += -lqserialdevice(d)
---

5. After compile, for running your application, move (or copy) library qserialdevice(d).dll
to directory with yourapplication.exe

6. Running yourapplication.exe

very very nice, thanks!

under windows, I find it better than Qextserialport.

will try on linux too, soon.

thanks :)

Is it possibile to send whole byte by write(...) I want send some array like 0x02,0x04,0x00,0x00,0x00,0xff and how to do it ? I need sends data from 0x00 to 0xff
Thanks for help

ehh (char)value

char data[256];
data[0] = 0x00;
...
data[255] = 0xFF;
...
port->write(data, 256);
...

Hi,

is in the windows code the SDK now required? (Compiler is showing missing header file)?

Bronko

What are headers? What you mean?
