Such errors comes from sse2/3 code in qt libs and  bindings must be compiled with -mstackrealign.


zeljko

So this binary from V2.4 are not compiled with -mstackrealign. ?
And is it possible to have a QT Binary that works from QT 4.5 until 4.7 ?
At the moment it seems that V2.1 works with all Qt's before 2.7 and the 2.1 compiled for Qt 4.7 ONLY works with Qt4.7 and not 4.6 / 4.5
