I just realized this is not done in the project file but in the call to qmake.

export QTDIR=/home/esutton/QtSDK/Desktop/Qt/473/gcc/bin
$QTDIR/qmake *.pro -r -spec linux-g++-64
make clean
make

$QTDIR/qmake *.pro -r -spec linux-g++-32
make clean
make

I just need to figure out how to conditionally name the output executable myapp32 or myapp64 or place the build output in the desired linux32 or linux64 folder.

I apologize for the added mailing list noise.
