I'm trying to build Boost on Windows with the 32-bit binaries supplied by http://www.equation.com/servlet/equation.cmd?call=fortran. Aside from about 10 billion "visibility attribute" warnings, everything appears to compile correctly except the Thread library: (running from a Windows command prompt) bjam toolset=gcc link=static runtime-link=static stage The build output that I get is below, but it looks like something is wrong with the macro configuration when including boost/detail/interlocked.hpp. Any help? ----- Performing configuration checks - has_icu builds : no warning: Graph library does not contain MPI-based parallel components. note: to enable them, add "using mpi ;" to your user-config.jam - ../config//has_long_double_support builds : yes warning: skipping optional Message Passing Interface (MPI) library. note: to enable MPI support, add "using mpi ;" to user-config.jam. note: to suppress this message, pass "--without-mpi" to bjam. note: otherwise, you can safely ignore this message. warning: Unable to construct ./stage-unversioned warning: Unable to construct ./stage-unversioned
