I using rev 2509 + MinGW + WinXP.
In my computer, QT's directory looks like: additional file 1, but in the new project that created from QT Application template, the project build options is: additional file 2.
Otherwise, i had set a WindowsXP SYSTEM variable: "QTDIR=D:\Program\Qt"; and added a variable "QTDIR=D:\Program\Qt" at "Settings\GNU GCC Compiler\Customer variables". But C::B seems to not notifed the variable. So i had to add the variable at "Project\Build options\default\GNU GCC Compiler\Customer variables", this time C::B has notified the variable.
Sorry for my english.
