Dear @KeHao.Qian,
I am glad that you found the source of the problem. But i am sorry, i cannot help you more because i have never faced your problem. In my research, i have changed the source code of OpenFAST but it is very simple change in such a way that i think anyone can do it. Then, i have no problems in recompiling. Further, i dont have experience in recompiling because as i told you i still at the basic level in changing the source code of OpenFAST.
I am so sorry.
Maybe, @Jason.Jonkman can help or anyone from NREL team.
Best Regards,
Riad
