I did a little search around segmentation fault in this case, gonna change my Qt version to see if that will make a difference.

Hi and welcome to devnet,

AFAIK and after a quick look in the documentation, there doesn't seem to be such a signal

Hi,

You can find this documentation in qmake's manual.

Are you sure that the pc files from QtGstreamer can be find by pkg-config ?

Hello

I am trying to do something similar. I downloaded QtGStreamer library. I compiled at installed it at /usr/local/TrollTech/Qt-4.8.5. When I try to run the example it did not find pkgconfig QtGStreamer-0.10.

I can see that QTStreamer has installed all their libs/pkconfig at /usr/local/TrollTech/Qt-4.8.5/lib/i386-linux.gnu and I think QtCreator is looking for them at /usr/local/TrollTech/Qt-4.8.5/lib/

How can I configure QtCreator to look for this other directory?

Thanks

please also refer to the following post for more common errors that happend

can someone please tell the steps for deploying a custom plugin .
code not required just the dteps as i am having difficulties deploying

Hi Everyone,

Thanks for your valuable reply. I am very comfort with qt creator IDE. Part my code was in .net active X dll ,that's the reason i like to integrate qt with Visual studio. I have just tried simple " helloworld" program in Qt creator.I really impressed with Qt creator IDE itself.

Regards,

SOLVED!

This tutorial works well: http://stackoverflow.com/questions/15881913/how-to-link-opencv-in-qtcreator-and-use-qt-library

Building OpenCV with MinGW is a must!
...and then everything is working fine

[quote author="SurlyDuff" date="1380686616"]Hi cokefish,

Creating a system environment called LIBRARY_PATH and setting it to C:\Qt\5.1.1\mingw48_32\bin solved the problem for me.

On your system, you may have to set the LIBRARY_PATH environment variable to C:\Qt\Qt5.1.1\5.1.1\mingw48_32\bin[/quote]

solved it for me too, thank you!

I have another question. Before trying setting the LIBRARY_PATH variable I've added LIBS += -L"QTLIBDIR..." in the qwt.pro file. Why didn't this work ?

Why you do not use a "QtSerialPort":http://qt-project.org/wiki/QtSerialPort library instead of QExtSerialPort?

Hi, i was linking the libraries with the older installed version. I had two versions of ITK and VTK libs installed. I changed the path, everything was fine. Thanks a lot for your guidance...

Thanks a lot uwer.
It seems I had stopped one step too soon when walking down from qwt_plot.

[quote author="langi667" date="1380449159"]Yes I already read the article, but all listed rendering libs are GPL and their seeding licenses are way to expensive. [/quote]

If you want to do it yourself the article provides ideas how to use QPrinter to create a PDF. Btw some of the libraries stated at the article are with LGPL and Apache 2.0 licence.

Hi,

the simplest way is to call EXECUTE_PROCESS.

No worries, did you make it work ?

[quote author="koahnig" date="1379584558"]What you are referring to is not the general case of set(Raw)Samples.
Use "QPlotCurve::setSamples":http://qwt.sourceforge.net/class_qwt_plot_curve.html#a67b24f3663484ff5e973a288c6071b2a
AFAIK this refers to the more common usage within QWT . [/quote]
If I understand correctly, you advise to use QVectors.
Hmm... I fear this to be far too "heavy" for what I want.
Thanks anyway for helping.

Hi.

Good to see someone else is using this library to do things!

If you have installed the Cypress USB Suite 3.4.7. There are files in C:/Cypress/Cypress Suite USB 3.4.7/CyAPI

You want the CyAPI.lib in the lib/x86/ folder (I used the one from x64, which created the problem). Put this in your Qt project directory lib/ then grab all the header files in C:\Cypress\Cypress Suite USB 3.4.7\CyAPI\inc and put them in your project directory inc/ folder

You can then use the code here to link the library to your project:

@
#Add CyAPI lib
win32: LIBS += -L$$PWD/lib/ -lCyAPI
INCLUDEPATH += $$PWD/inc
DEPENDPATH += $$PWD/inc
@

Make sure when you use the library, include <Windows.h> because CyAPI uses a lot of the windows definitions.
