When using qwt a lot of warning appear during compilation:
..\..\..\qwt\qwt-6.0.0\src/qwt_interval.h:270: warning: 'bool QwtInterval::isValid() const' redeclared without dllimport attribute after being referenced with dll linkage
In qwt examples it is about 20 warnings each, but on bigger projects it gets into an unclear state because these warnings are flooding the compiler output and you are able to miss real warnings....
Is there any solution?
[working with QT4.70, QWT 6.0.0, Windows 7 64Bit (Compiler:MinGW) ]
Added after 14 minutes:
in advance:
posts like "on my linux-system everything works fine" or "Iam working under debian 16core nonX86er powerpc and VS 2010" does not help,
I am afraid this warning is Win7+QWT or even Win7+QWT+minGW specific.
