I get a compiler error when trying to create a project with a .ui file I created in designer.

the error is "This file was generated using the moc from 4.6.4 lt"
"cannot be used with the include files from this version of QT"
"The moc has changed too much"

My software versions are as follows:
RHEL 6.7
QT 4.8.4
Qt Creator 3.0.1 GCC 4.4.7
QT Designer 4.6.2
QWT 6.1.3

Any help would be appreciated.
