Qwt app compile error

[ajb]

Fixed. Had to first do a clean / rebuild to see the effects of the changes. Then copied examples.pri into my .pro file, and narrowed down the key additional lines to the following:

QWT_ROOT = c:/Qt/qwt-5.2.0
INCLUDEPATH += $${QWT_ROOT}/src
QWTLIB       = qwt$${SUFFIX_STR}
LIBS   += -L$${QWT_ROOT}/lib -l$${QWTLIB}

QWT_ROOT = c:/Qt/qwt-5.2.0
INCLUDEPATH += $${QWT_ROOT}/src
QWTLIB       = qwt$${SUFFIX_STR}
LIBS   += -L$${QWT_ROOT}/lib -l$${QWTLIB}

Hi!

I'm recovering this thread because I have exactly the same problem. There's only one difference... i'm using QtCreator 1.3.1 based on Qt 4.6.2

The installation of qwt5.2 has been completed successfully and i've applied the solutions posted here before.

In my .pro file I have added:

QWT_ROOT = C:\Qt\2010.02.1\qt\Qwt-5.2.1
 
INCLUDEPATH += $${QWT_ROOT}\include
 
QWTLIB       = qwt5$${SUFFIX_STR}
 
LIBS        += -L$${QWT_ROOT}\lib\qwtd5.dll -l$${QWTLIB}
 
DEFINES += QWT_DLL

QWT_ROOT = C:\Qt\2010.02.1\qt\Qwt-5.2.1

INCLUDEPATH += $${QWT_ROOT}\include

QWTLIB       = qwt5$${SUFFIX_STR}

LIBS        += -L$${QWT_ROOT}\lib\qwtd5.dll -l$${QWTLIB}

DEFINES += QWT_DLL

To copy to clipboard, switch view to plain text mode 

All seems to work perfectly since the program exits unexpectedly returning -1073741515

Could the problem be related with incompatibility between qwt5.2 and qt4.6.2 ? I don't think so but I really don't know.

I would appreciate any suggestions! I'm very stucked right now! Thanks!

I'm using Windows, by the way.

Hi,
I do have the same problem when I try to compile it with the qtcreator...
So tried using the Qt Command Prompt and the pro executed with out any problem...
But in order to open the .exe genrated I copied the qwt5.dll to the debug folder where the exe was generated...
then it worked well

win32 {
INCLUDEPATH += C:/Qt/qwt-5.2.0/src #your path for qwt source code
LIBS += -L C:/Qt/qwt-5.2.0/lib/ -lqwt5 #your path for qwt lib files.
}
after adding it you need to go to qt Command prompt and
enter
qmake ****.pro
mingw32-make
this will do it but you need to put the QtGui4.dll,QtCore4.dll,QtSvg4.dll and qwt5.dll into the debug folder and then open the executable file...
