Mingw32 problem when making install of qwt-6.01

[Soren]

Hi
first im impressed with the qwt library.
thanks for your great effort.

im sorry to add to the long list of mingw/qwt post.
but i have been struggling along time to get the qwt library to install correctly
code compiles fine with mingw32-make
im following the install file instructions.
i installed latest QTsdk 4.80. im using windows7 64bits
the directory C:/qwt-6.0.1 is not created
but when try to make install i get following errors by using -d switch:

Is there anyone who succesfully installed qtsdk and qwt on windows7 64bit.
as i understand with all plugins you have to recompile qtcreator with mingw.
i have now spent 2 months just installing and recompiling.
i tried to follow the guide made by Uwe closely.
is it nessesary to use 64bit mingw version?
please help me im spending too much time just setting up the system.

Hi Soren,

I cant comment on the install failure to much, but if you are trying to incorporate Qwt into the Qt SDK I think it is causing your problems. The SDK is compiled with visual studio and as such I think you are probably going down the path that I originally did which does not like to mix build types (I am a complete noob in this area). I had to compile the Qt creator and libraries with mingw and then also did the same with the Qwt e.g. everything is built with the same compiler. I dont know about the 64 bit problem but I don't think its that. Here is my link below for how I got it all to work. I hope it helps since it can be really frustrating, but awesome when its all go.
