d - How to install two versions of Qt and tell the application which to use? -

-

i developing application in qt, using d language (with qtd binding). i've noticed app crashes qt 4.7.x, need use qt 4.6.2 instead. in system qt 4.7.2 installed. unfortunately neither make qtd work latest qt versions nor (i'm afraid) count on qtd developers...

the thing need make application install in system qt 4.6.2 libs , use it, let other applications still use qt 4.7.2. possible? if is, how then?

the answer question version of qt determined qmake use generate makefile.

/opt/qtsdk/qt-4.6.2/bin/qmake

/opt/qtsdk/qt-4.7.3/bin/qmake

each use library in directory.
