well Boris Kolpackov, i found this...

/home/leoxnidas/Qt/5.5/gcc/include/QtCore/qglobal.h:1067:4: error: #error
"You must build your code with position independent code if Qt was built
with -reduce-relocations. " "Compile your code with -fPIC (-fPIE is not
 #  error "You must build your code with position independent code if Qt
was built with -reduce-relocations. "\

but i am not sure how to use -fPIC;  this is my input ...

./configure --with-pic=PIC CPPFLAGS=-I/home/leoxnidas/Qt/5.5/gcc/include
LDFLAGS=-L/home/leoxnidas/qt/5.5/gcc/lib --prefix=/home/leoxnidas/Qt/5.5/gcc
