早上刚解决的,供参考。
1) open the qmake.conf of your platform (for me its C:\Qt\4.8.3\mkspecs\win32-g++)
2) search for QMAKE_IDC
3) add the following line after the QMAKE_IDC line:
QMAKE_RCC = $$[QT_INSTALL_BINS]$${DIR_SEPARATOR}rcc.exe
4) save file and clsoe
5) restart all your dev tools and remove all auto generated Makefiles
6) recompile
