QWT

I can creata and QWT apps for my Desktop with QT creator . But I can't
compile the apps for my mini 2440. 

I can compile a Gui app without Qwt for mini 2440, If ı want to use
qwt , ı get errors like this : 

/home/mcelal/untitled/../../../usr/local/qwt-6.0.2-svn/lib//libqwt.so:-1:
error: file not recognized: File format not recognized

:-1: error: collect2: ld returned 1 exit status
