关于qt4.6.1 qt version 的debugging helper 不能rebuild
在qt4.6。1的tools-》options里面的qt versions里面
里面有一个是manual
qmake location ：。。。\qt\2010.01\qt\bin\qmake.exe
mingw location ：。。。\Qt\2010.01\mingw
然后debugging helper 上显示的确是X，然后rebuild下以后就显示log
：

不知道这个不能rebuild会不会对程序运行造成一定的影响？
请高手指教！
[解决办法]
环境变量的问题，把你环境变量中VC98的给去掉
[解决办法]
都去掉。用mingw的话，跟vc没有关系
