Qwt Execute application

Beberd

Hi,

I have installed Qwt plugin (6.1.0) and I have Qt 5.0.1.
I try to run a qwt application.
here my .pro file:

@include( /usr/local/qwt-6.1.0-svn/features/qwt.prf )

QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Project
TEMPLATE = app

CONFIG += qwt
SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

#QWT

unix:!macx: LIBS += -L$$PWD/../../../../../usr/local/qwt-6.1.0-svn/lib/ -lqwt

INCLUDEPATH += $$PWD/../../../../../usr/local/qwt-6.1.0-svn/include
DEPENDPATH += $$PWD/../../../../../usr/local/qwt-6.1.0-svn/include@

and here my main.cpp

@
#include "mainwindow.h"
#include <QApplication>
#include <qwt_plot.h>

int main(int argc, char argv[])
{
QApplication a(argc, argv);
QwtPlot plot = new QwtPlot(0);
return a.exec();
}@

It simple and I can't execute my App.

I have these erros:

@*** glibc detected *** /home/: realloc(): invalid pointer: 0x05aa2d1c ***
======= Backtrace: =========
/lib/i386-linux-gnu/libc.so.6(+0x75ee2)[0x46aee2]
/lib/i386-linux-gnu/libc.so.6(realloc+0x25d)[0x46f56d]
/lib/i386-linux-gnu/libc.so.6(realloc+0x273)[0x46f583]@
etc...

Anyone got an idea of the problem?

Hi,

Are you sure Qwt is compiled with your Qt 5.0.1 ?

Also you have a memory leak. You don't destroy plot when your application ends
