problem building 1.61.0

[drmhkelley@…]

Brand new to boost. Downloaded and (apparently successfully) built version 1.61.0. Using recent (I think most recent) version on cygwin64 on Windows 10. First use was to try the tutorial programs for the boost filesystem package. Below is the linker output for tut1.cpp

Any suggestions what I may have done wrong or where to look for solution?

Hi, you need to link with boost_system. Frédéric
