hello,i have same error and can you tell me what you do to fix it... really need you help!!
If you have the same error, why don't you post in the same thread?
What Qt version are you compiling? For which board? How did you configure Qt? What steps did you take to configure Qt Creator?
The OP did not specify -extprefix nor -hostprefix for his config, which might contribute to the problem.
However, I think he simply misconfigured Qt Creator (pointed cross compilation Kit to desktop Qt version, instead of the cross compiled one).
