QDevelop, a new IDE for Qt4

[triperzonak]

i found the answer:

i copied g++.exe from dir\mingw\bin...

why do we need to copy mingw\bin apps. to bin of qt? em i missing something?

then the the error was gone...

while im fixing the error i found a bug from qdevelop (latest).. i tried to copy all the file from mingw\bin then erase it one or by group to know what application fixed the error, i run rebuild everytiime i erase an application or group then suddenly after several run of rebuild (without editing the code) qdevelop crash..
