Hello Dane,Do you build Qt yourself? Prebuilt Qt binaries always default to release build (CONFIG+=release), unless you pass CONFIG+=debug to qmake. However, when you build Qt yourself, depending on configure options you specify, it can default to debug build (CONFIG+=debug) and you have to specify CONFIG+=release explicitly if you want to build in release mode. AFAIK, Qt Creator assumes that Qt defaults to release build so it doesn't explicitly pass CONFIG+=release to qmake.

One thing that I do notice is that I don't see +=Release in the build string: 10:04:08: Starting: "/usr/bin/qmake-qt4" /home/duane/QtSDK/PT500Projects/visu32/visu32.pro -r -spec linux-g++ 10:04:08: The process "/usr/bin/qmake-qt4" exited normally. 10:04:09: Starting: "/usr/bin/make" g++ -c -pipe -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom -fasynchronous-unwind-tables -O2 -Wall -W -Wno-write-strings -Wno-unused-parameter -Wno-unused-variable -DBPP32 -DPT470BUILD -I/usr/lib/qt4/mkspecs/linux-g++ -I../visu32 -I../../../SVN_Repos/PT470Development/src/include -I../../../SVN_Repos/PT470Development/OpenGUI/src -I../../../SVN_Repos/PT470Development/OpenGUI/src -I../visu32 -I. -o main.o ../../../SVN_Repos/PT470Development/src/visu32/main.cpp ...When I build with 4.8.1 is see this: 10:20:09: Starting: "/home/duane/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake" /home/duane/QtSDK/PT500Projects/visu32/visu32.pro -r -spec linux-g++ CONFIG+=release 10:20:09: The process "/home/duane/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake" exited normally. 10:20:09: Starting: "/usr/bin/make" ...
