[Qt-interest] Installing 4.5 SDK on Linux

Tue Apr 7 05:34:52 CEST 2009

Thanks JD.  I let both installs use their default locations.  Everything
seems to be running and compiling ok now... At least so far.  I'll keep
working and see if it holds together.

Thanks for your help!

Judy,

Forgive me but I was away for a few days.  If you are using any version of
Ubuntu prior to the beta release of 9.04 you will have 4.4 in the repos.  I
should have told you that I did it on a 9.04 install ... sorry.

Now as you your questions of mixed versions you should have to worry because
the 4.4 version you installed from the repos will be a system install and in
different directories from any install you tried to compile yourself.  That
is ofcourse if you didn't tell Qt to place the libs into the /usr/lib
folder.

Cheers,

JD
