Knut resource converter

yurim

Hi every body,
my compliments for the community.
I have to translate some source code from C# to Qt. I found a tool named Knut and with it my work may me easier.
For install this tools it's tutorial say this:

1_ cd knut-version # directory was created by tar
2_ qmake knut.pro # generate all the Makefiles
3_ nmake # (of course QTDIR must be set)

step 1 and step 2 are ok. When i try to write nmake in the cmd i have the following problem:
C:\knut\knut-1.0.1>nmake

    cd extractor\ && ( if not exist Makefile C:\Qt\Qt5.1.1\5.1.1\msvc2010_op

engl\bin\qmake.exe C:\knut\knut-1.0.1\extractor\extractor.pro -o Makefile ) && C
:\knut\knut-1.0.1\nmake.exe -f Makefile

NMAKE : fatal error U1073: don't know how to make '/usr/share/qt3/mkspecs/defaul
t/qmake.conf'
Stop.
NMAKE : fatal error U1077: 'cd' : return code '0x2'
Stop.

Some one can help me?
Thanks to all
Yuri
