qwtplot3d examples build problem

[<luk...@o2...>]

Hi,
I am using mingw32-make (GNU Make 3.81) on Windows XP sp2, to compile qwtplot3d (QT-4.4.0; qwt-5.1.1 ). Both Qt and qwt examples work OK. Qwtplot3d compiles OK. The problem occurs when I try to compile the qwtplot3d examples. Below is the compiler's output (an excerpt from examples compilation (with mingw32-make) verbose):

g++: /NODEFAULTLIB:msvcrt: No such file or directory
g++: ../../lib/qwtplot3d.lib: No such file or directory
mingw32-make[2]: *** [..\bin\simpleplot.exe] Error 1
mingw32-make[2]: Leaving directory `C:/DEVEL/qwtplot3d/examples/simpleplot'
mingw32-make[1]: *** [debug] Error 2
mingw32-make[1]: Leaving directory `C:/DEVEL/qwtplot3d/examples/simpleplot'
mingw32-make: *** [sub-simpleplot-make_default] Error 2

I am running out of solutions, Can anybody please give some hints on this?
Best, 
Lukasz
