Ok so the question is, is your boost installation done correctly, and are you using the correct version of boost ?
boost version is obviously is the issue here. The Op method of installing boost within MXE showed 1.60.0 version. The Eidas coin link method install
boost as separate package outside mxe using "1_63_0" version. I followed everything exact steps in the Eidas Coin link doc method using "1_63_0" boost version for this error report.
MXE has greatly improved it's package installation system. You should use MXE to install it by changing the version/hash of boost in mxe/src/boost.mk. then doing make boost
