I am Trying to compile and install the QWT-6.1.2 along with my QT 5.3.2 on a windows 8 PC .... after running the Commands on my QT command promt, "qmake qwt.pro" followed by mingw32-make" ... I am receiving this Error Screenshot_3.png .... I do have this feeling it has something to do with the Operating system than the qwt or Qt Creater itself , Please help , Thank you in Advanced
