Hello world,

can help me please for the installation of qwt ? I have a search on the forum i have tried several "UWE installations" like this :

1°) Unzip Qwt to "C:\Qt\qwt-6.0.0"
2°) open Qt command line "QT 4.7.3 for desckop (MinGW)"
3°) qmake qwt.pro
4°) mingw32-make
5°) mingw32-make install
6°) qmake -set QMAKEFEATURES "C:/Qt/qwt-6.0.0/features"
7°) add "CONFIG += qwt" in my project .pro
8°) in my Qt project i run "Compiler->execute Qmake"
9°) and i compil my project

but i have already this error during compilation :
"qwt_plot_curve.h : No such file or directoty"

Can you explain what is the error in my installation ?

thanks !
