Hello, I work on a new project and I have to use qt, qwtpolar et qwtplot3d with visual studio c++ 2010. As you I can compile qt-open-source-4.7.3 and it’s work in Visual studio. But I have to use also qwtpolar and qwtplot3D.
So I do the same operation for this 2 solutions :
cd C:\UTOX\QT\qwtpolar
qmake
nmake
when I start the nmake a fatal error nmake appear.

I try to the QMAKEFEtURES variable and re start the compile of qt but it is always impossible to compile the others library.

So can you help me ?
In your explications I don’t understand where the environment variable is used ?
Please help me !
