Is that a patch we should: a) submit upstream to libevent b) patch locally in Open MPI ? > it seems "opal/mca/memory/patcher" is new compared to 1.10.x and the > compilation fail > > > /cygdrive/e/cyg_pub/devel/openmpi/v2.1/prova/openmpi-2.1.2-0.3.x86_64/src/openmpi-2.1.2rc3/opal/mca/memory/patcher/memory_patcher_component.c:98:32: > warning: implicit declaration of function ‘syscall’ > [-Wimplicit-function-declaration] > #define memory_patcher_syscall syscall > ^ > /cygdrive/e/cyg_pub/devel/openmpi/v2.1/prova/openmpi-2.1.2-0.3.x86_64/src/openmpi-2.1.2rc3/opal/mca/memory/patcher/memory_patcher_component.c:165:18: > note: in expansion of macro ‘memory_patcher_syscall’ > result = memory_patcher_syscall(SYS_munmap, start, length); > ^~~~~~~~~~~~~~~~~~~~~~ > /cygdrive/e/cyg_pub/devel/openmpi/v2.1/prova/openmpi-2.1.2-0.3.x86_64/src/openmpi-2.1.2rc3/opal/mca/memory/patcher/memory_patcher_component.c:165:41: > error: ‘SYS_munmap’ undeclared (first use in this function) > result = memory_patcher_syscall(SYS_munmap, start, length); > > > can someone guide me on the scope of new component in > which case is supposed to be included ? > I supposed it should be excluded like the others linux > and malloc_solaris directory Yes, "patcher" replaces the old malloc hooks. I don't think we looked at how patcher would function on Cygwin at all -- it probably isn't relevant on Windows, because it's only necessary for OS-bypass networks (which I'm pretty sure Open MPI doesn't support on Windows). -- Jeff Squyres jsquy...@cisco.com _______________________________________________ devel mailing list devel@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/devel
