I am getting some undefined references in building OpenMPI 1.5.4 and I would like to know how to work around it.
The errors look like this: /scratch1/bloscel/builds/release/openmpi-intel/lib/libmpi.a(topology-linux.o): In function `hwloc_linux_alloc_membind': topology-linux.c:(.text+0x1da): undefined reference to `mbind' topology-linux.c:(.text+0x213): undefined reference to `mbind' /scratch1/bloscel/builds/release/openmpi-intel/lib/libmpi.a(topology-linux.o): In function `hwloc_linux_set_area_membind': topology-linux.c:(.text+0x414): undefined reference to `mbind' topology-linux.c:(.text+0x46c): undefined reference to `mbind' /scratch1/bloscel/builds/release/openmpi-intel/lib/libmpi.a(topology-linux.o): In function `hwloc_linux_get_thisthread_membind': topology-linux.c:(.text+0x4ff): undefined reference to `get_mempolicy' topology-linux.c:(.text+0x5ff): undefined reference to `get_mempolicy' /scratch1/bloscel/builds/release/openmpi-intel/lib/libmpi.a(topology-linux.o): In function `hwloc_linux_set_thisthread_membind': topology-linux.c:(.text+0x7b5): undefined reference to `migrate_pages' topology-linux.c:(.text+0x7e9): undefined reference to `set_mempolicy' topology-linux.c:(.text+0x831): undefined reference to `set_mempolicy' make: *** [main] Error 1 Some configure output that is probably relevant: checking numaif.h usability... yes checking numaif.h presence... yes checking for numaif.h... yes checking for set_mempolicy in -lnuma... yes checking for mbind in -lnuma... yes checking for migrate_pages in -lnuma... yes The FAQ says that I should have to give -with-libnuma explicitly, but I did not do that. Is there a problem with configure? Or the FAQ? Or perhaps the system has a configuration peculiarity? On another system, the configure output is different, and there are no unresolved references: checking numaif.h usability... no checking numaif.h presence... no checking for numaif.h... no What is the configure option that will make the unresolved references go away? Thanks, Ed
