[Qt-creator] Cannot mix incompatible Qt libraries

[Bryan Greenway]

Thanks for your responses!  I'll try to respond to all of them here.

 

I seem to have a partial Qt install in /usr/local/lib vs a more complete
(and apparently later version) in /usr/lib/.  I'm not quite sure how it got
there, but I'm sure I did it somehow.  Can I just delete the Qt files from
that directory?  I attached a screen shot showing the file listings in both
/usr/lib and /usr/local/lib.  

 

I've attached screen shots of the Tools>Options>Qt4 dialog.  I have a couple
of observations: 1-the path is not editable for System Qt and is set to
/usr.  2 - When I highlight System Qt in the list box, a not appears that
says "Found Qt version 4.4.3 using mkspec /usr/share/Qt4/mkspecs/linux-g++".
I looked in that directory, but only found two files: qmake.conf and
qplatformdefs.h.

 

It was suggested that I might have $QTDIR set.I'm sorry, but I'm new to
linux.  Is this an environment variable or something inside of Qtcreator?
How do I check/change this?

 

Here is the entire listing from Qtcreator's Compile output window after
performing a Clean All and Rebuild All on my project.  I don't see the
linker line that starts with "g++ -Wl,-z,origin" as suggested.

 

Thanks VERY much for your help!
