error in compling OpenFAST in Ubuntu 14.04

I’m not familiar with Ubuntu. I’m trying to compile OpenFAST in Ubuntu 14.04 but I got some trouble which could be seen in the picture below. I don’t know what’s the meaning of undefined reference to ‘pthread_create’. Any reply is very grateful.

Dear @Pengnan.Ma,

It looks like you posted the same question on the OpenFAST github issues page: error in compling OpenFAST in Ubuntu 14.04 · Issue #1038 · OpenFAST/openfast · GitHub. I don’t know the answer to your question. In general, I suggest using github issues for all source code and compiling related questions. This forum is likely preferred for OpenFAST usage-related questions.

Best regards,
