Folks, for both trunk and v1.8 branch, configure takes the --with-threads option. valid usages are --with-threads, --with-threads=yes, --with-threads=posix and --with-threads=no
/* v1.6 used to support the --with-threads=solaris */ if we try to configure with --with-threads=no, this will result in a fatal error : checking for working POSIX threads package... yes checking for type of thread support... none configure: error: User requested MPI threads, but no threading model supported bottom line, the --with-threads configure option is useless in both v1.8 and trunk. is there any plan to support --with-threads=no in the future ? if no, i'd like to simply remove the --with-threads option Thanks in advance for your feedback Gilles FYI there is still some dead code / bug related to solaris threads, and this will be removed / fixed see https://svn.open-mpi.org/trac/ompi/ticket/4911
