qmake reports multiple targets and stops

I am working on Qt 5.1.0 with Qt creator 2.7.2 with minGW on windows7(sp1) I tried to build the hello project from command line (C:\Qt\Qt5.1.0\5.1.0\mingw48_32\exaples\qmake\tutorial\) as presicribed by the qmake manual. I created hello.pro. qmake -o Makefile hello.pro works fine. But , “make” results in the following error, Makefile : 62: ***multiple target patterns. stop Thanks in advance for all your helps, Really appreciate your valuable time Naveen C K
