realtime_plot example problem--help needed.

[swamyonline]

hi ppl,
iam trying to copy the realtime_plot example project into my own folder and trying to execute it.

iam doing it in windows with QDevelop.

1. I copied all the .cpp and .h files into my own folder.
2. Created a new project and added those realtime_plot files to it.
3. Set the env variables INCLUDEPATH += c:\qwt-5.1.1\include
LIBS += c:\qwt-5.1.1\lib\libqwt5.a
4. Set project settings to release and warn on.

with those settings, i was able to compile it successfully. But when i tried to execute it, its giving error message "The application failed to intialize properly(0xc0000005). Click on OK to terminate the application".

the project settings file:

TEMPLATE = app
SOURCES += realtime.cpp \
mainwindow.cpp \
randomplot.cpp \
incrementalplot.cpp \
scrollbar.cpp \
scrollzoomer.cpp
CONFIG += release warn_on
HEADERS += mainwindow.h \
randomplot.h \
incrementalplot.h \
realtime.h \
scrollbar.h \
scrollzoomer.h
INCLUDEPATH += c:\qwt-5.1.1\include
LIBS += c:\qwt-5.1.1\lib\libqwt5.a

what could be the real mistake i hv done? im trying execute the same example program without any code modification, except with a new .pro file other than the example .pro file.

Can any body point it out and tell me the problem...thanks in advance.
