HPX does not build with Boost 1.58.0 #1527

I am trying to build HPX 0.9.10 with Boost 1.58.0. This is on OS X using clang 3.6.0. The build aborts with the error message

/Users/eschnett/software/boost-1.58.0/include/boost/serialization/vector.hpp:216:18: error: comparison of integers of different signs: 'int' and 'base_type' (aka 'unsigned long') [-Werror,-Wsign-compare]
    for(i = 0; i < count; ++i){
               ~ ^ ~~~~~

This looks as if Boost misbehaved, iterating over the element of std::vector using int (why???). HPX then adds -Werror to the mix, leading to this build failure.

It is customary to disable -Werror in released versions for this reason.

This problem sounds oddly familiar; was this discussed before?

You reported that before (see #1475). As said, Boost V1.58 was not released at the point when we released HPX V0.9.10.

Until the next release of HPX please patch your local copy of HPX by removing the -Werror flag locally (
