run qwt example in Qt 5 on linux ubuntu

[natile]

I cant figure out what i need to do for runing example program which use qwt library. I download the file qwt-6.1.2.tar.bz2 from here as usual it goes to Download Direcory and i extract the file to this directory. I have now qwt-6.1.2 directory in Downloads directory.

The qt directory in my machine located in /opt/Qt5.4.1/

How i continue from here ??

I try to run qmake :

natile@natile-Precision-T1650:/opt/Qt5.4.1/5.4/gcc_64/bin$ sudo ./qmake /home/natile/Downloads/qwt-6.1.2/qwt.pro

And after i ran make :

natile@natile-Precision-T1650:/opt/Qt5.4.1/5.4/gcc_64/bin$ sudo make

but i get an error:

cd src/ && ( test -e Makefile || /opt/Qt5.4.1/5.4/gcc_64/bin/qmake /home/natile/Downloads/qwt-6.1.2/src/src.pro -o Makefile ) && make -f Makefile make1: Entering directory /opt/Qt5.4.1/5.4/gcc_64/bin/src'

I understand that i have to run qmake

I get nothing in the installation url : http://qwt.sourceforge.net/qwtinstall.html

Please help.

I'm not able to help much, but anyway...I had similar problems when trying to build qwt library from source. I've buid it ok with mingw compiler, while with msvc I wasn't able to. So my best guess is, that compilers have subtle diferences and kind of preferences with code syntax. On qwt site, if I remember wll, you have different sources available (probalby meant for different compilers, but I'm not sure). You could also try a differnet compiler instead of gcc.
