It also turns out that I've been told we do not need MPI, which is good because we don't have MPI compilers installed on our builders, so "using mpi ;" did nothing (understandably). That was probably the problem all along FWIW. Thanks, Nick On Fri, Jan 17, 2025 at 7:49 AM Дмитрий Архипов via Boost-users < boost-users@lists.boost.org> wrote:

It turns out, the problem is that you need to configure the mpi module. Put
using mpi ;
into either user-config.jam or project-config.jam (the former is better, because the bootstrap script rewrites project-config.jam).
Boost.MPI was supposed to tell you that you need to do this, but something made this part to do nothing:
message boost_mpi : "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 b2." : "note: otherwise, you can safely ignore this message." ; _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org https://lists.boost.org/mailman/listinfo.cgi/boost-users
