Using Qwt in eclipse CDT

[Lawand]

I edited qwtconfig.pri and removed this line:

CONFIG           += QwtDll

CONFIG           += QwtDll

To copy to clipboard, switch view to plain text mode 

thus, building Qwt as a static library,
and the problem is solved

Thanks guys for your help.

Hi,
I am trying something similar and having the smae problem. Basically, I want to have an attitude indicator in an application exactly like the qwt example. I have compiles qwt fine and have successfully compiled and run the samle with the attitude indicator, and added a dial to the ui.

When I try to add the attitude_indicator.cpp and .h files to the project (without using them) it will still compile but returns

exited with code -1073741819

exited with code -1073741819

To copy to clipboard, switch view to plain text mode 

or

exited with code -1073741511

exited with code -1073741511

To copy to clipboard, switch view to plain text mode 

Running gdb returns

Program received signal SIGSEGV, Segmentation Fault.
Program exited with code 0x30000000005

Program received signal SIGSEGV, Segmentation Fault.
Program exited with code 0x30000000005

To copy to clipboard, switch view to plain text mode 

What could be causing this? This is my .pro file:

TARGET = Test1
TEMPLATE = app
 
 
SOURCES += main.cpp\
        mainwindow.cpp \
        attitude_indicator.cpp
 
HEADERS  += mainwindow.h \
        attitude_indicator.h
 
 
FORMS    += mainwindow.ui
 
INCLUDEPATH += "C:\Qwt-5.2.0\include"
LIBS += -L"C:\Qwt-5.2.0\lib" \
        -lqwt5

TARGET = Test1
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp \
        attitude_indicator.cpp

HEADERS  += mainwindow.h \
        attitude_indicator.h


FORMS    += mainwindow.ui

INCLUDEPATH += "C:\Qwt-5.2.0\include"
LIBS += -L"C:\Qwt-5.2.0\lib" \
        -lqwt5

Any ideas would be appreciated. Thanks

Perhaps you should put the Qwt dll file next to the binary (exe) file.

Thanks Lawand, unfortunately that did not help. I have solved the problem from your idea though. I had a whole bunch of dlls in the exe folder already and since I reinstalled qt a few days ago the QtGui4.dll did not like playing with Qwt5.dll (possibly from different compiler versions?).

Thanks for your help
