Undefined Reference QwtPlot::QwtPlot(QWidget*)

[27Loco]

Hi,

I am using Ubuntu 9.04 with the qt4, qt creator and installed qwt using the synaptic manager. Looked like everything worked fine for me. The Designer has the new plugins.

Started a new project and added a plot widget to a dialog, but when I am trying to compile it fails because it cannot include #include "qwt_plot.h"

I know how to add new include paths in visual studio but I have no idea how to do that in QTCreator or does somethin different went wrong ?

Thanks in advance for your help

kind regards

EDIT:
Ok this is what I did:

copying the *.h files in src/ to /usr/local/include/:

# cp src/*.h /usr/local/include

# cp src/*.h /usr/local/include

To copy to clipboard, switch view to plain text mode 

copying those in lib/ to /usr/local/lib/.

cd lib && tar -cf l.tar *
 # 
 # mv l.tar /usr/local/lib
 # cd /usr/local/lib
 # tar xf l.tar
 # rm l.tar

cd lib && tar -cf l.tar *
 # 
 # mv l.tar /usr/local/lib
 # cd /usr/local/lib
 # tar xf l.tar
 # rm l.tar

To copy to clipboard, switch view to plain text mode 

running ldconfig:

#ldconfig

#ldconfig

To copy to clipboard, switch view to plain text mode 

No more include error but another one appears:

"undefined reference QwtPlot::QwtPlot(QWidget*)"

"undefined reference QwtPlot::QwtPlot(QWidget*)"

To copy to clipboard, switch view to plain text mode 

Any suggestions ? Sounds like the libs are missing
