Hi, as far as I can see, you've got another problem: the binaries from qt-project.org were configured with the -reduce-relocations switch (and thus build with the -fPIC compiler switch), which means that your executable / library also must be compiled with position independent code activated (see: http://en.wikipedia.org/wiki/Position-independent_code).
All in all it's just adding the -fPIE (when building an executable) or -fPIC command line switch (when building a library) to the compiler arguments (in case you're using gcc). E.g. using CMake as build system (>= 2.8.9), it's as simple as: set(CMAKE_POSITION_INDEPENDENT_CODE ON) to enable generating position independent code for all top level targets, or set_target_properties(<target> PROPERTIES POSITION_INDEPENDENT_CODE ON) to enable it only for the given <target>.
