[Qt-interest] Switching Qt Installation

[Frank Neuhaus]

Hi,

I installed Qt 4.5.2. with my Linux Distribution (Fedora)'s packet
manager. Now I want to compile the latest git version of Qt creator,
which unfortunately requires 4.6.0. I downloaded the 4.6.0 tech
preview edition, compiled and installed it. It installed into
/usr/local/Trolltech/Qt-4.6.0-tp1/.
The problem is that even when explicitly calling
/usr/local/Trolltech/Qt-4.6.0-tp1/bin/qmake, qmake generates Makefiles
that include /usr/include/QtSomething, which obviously belong to my
old Qt 4.5.2 installation. Environment variables such as QTDIR appear
to be ignored.
How can I tempoarily change my installation to 4.6.0 to compile Qt creator?

Thank you very much
   Frank
