[solved] resource problem: rcc can't find my *.qrc file with 4.8.3 Qt

[broadpeak]

I've installed the new Qt, and after rebuilding my project I got the next error message:

"process_begin: CreateProcess(NULL, bin\rcc.exe -name dockwidgets dockwidgets.qrc -o release\qrc_dockwidgets.cpp, ...) failed."

So, rcc.exe can't find my dockwidgets.qrc file.

Of course, in my .pro file I have the following line:
RESOURCES = dockwidgets.qrc

If I build my project with the previous Qt I have no error message...

Any idea?

EDIT: Solved!

In this file:
c:\Digia\Qt\4.8.3\mkspecs\win32-g++\qmake.conf
after the QMAKE_IDC line I insert this line:
QMAKE_RCC = $$[QT_INSTALL_BINS]$${DIR_SEPARATOR}rcc.exe
