thanks Rita,
i resolved the build errors with typecasting and proper path setting etc.
Now the problem is qt path for qmake on target . its taking the build system path i want that as to be target path it self
.i.e : /usr/lib/qt5/.
tried : qmake -query and found the wrong path.
how to change that to target qt installation path.??
