I have a linux/ppc64 host running Fedora 20. I have configured the 2.0.0rc2 tarball with
--prefix=[....] --enable-debug \ CFLAGS=-m32 --with-wrapper-cflags=-m32 \ CXXFLAGS=-m32 --with-wrapper-cxxflags=-m32 \ FCFLAGS=-m32 --with-wrapper-fcflags=-m32 --disable-mpi-fortran [yes, I know the fortran flags are pointless with --disable-mpi-fortran] My build is failing (as shown at the bottom of this email) in tools/wrappers with undefined references to udev symbols. The udev configure probe run by the embedded hwloc seemed happy enough: --- MCA component hwloc:hwloc1112 (m4 configuration macro, priority 90) checking for MCA component hwloc:hwloc1112 compile mode... static checking hwloc building mode... embedded [...] checking libudev.h usability... yes checking libudev.h presence... yes checking for libudev.h... yes checking for udev_device_new_from_subsystem_sysname in -ludev... no However, looking at config.log one can see that despite the presence/usability of libudev.h there is NOT a libudev library present for "-m32". This is apparent because the probe for udev_device_new_from_subsystem_sysname failed with a message about the *library* not being found rather than about an undefined symbol. I *can* work-around this issue by passing --disable-libudev to configure. However, it would seem appropriate to check for a usable libudev library in addition to the header. -Paul Making all in tools/wrappers make[2]: Entering directory `/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/BLD/opal/tools/wrappers' depbase=`echo opal_wrapper.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\ gcc -std=gnu99 "-DEXEEXT=\"\"" -I. -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/opal/tools/wrappers -I../../../opal/include -I../../../ompi/include -I../../../oshmem/include -I../../../opal/mca/hwloc/hwloc1112/hwloc/include/private/autogen -I../../../opal/mca/hwloc/hwloc1112/hwloc/include/hwloc/autogen -I../../../ompi/mpiext/cuda/c -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2 -I../../.. -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/opal/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/orte/include -I../../../orte/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/ompi/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/oshmem/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/opal/mca/hwloc/hwloc1112/hwloc/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/BLD/opal/mca/hwloc/hwloc1112/hwloc/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/opal/mca/event/libevent2022/libevent -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/opal/mca/event/libevent2022/libevent/include -I/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/BLD/opal/mca/event/libevent2022/libevent/include -m32 -g -finline-functions -fno-strict-aliasing -pthread -MT opal_wrapper.o -MD -MP -MF $depbase.Tpo -c -o opal_wrapper.o /home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/openmpi-2.0.0rc2/opal/tools/wrappers/opal_wrapper.c &&\ mv -f $depbase.Tpo $depbase.Po /bin/sh ../../../libtool --tag=CC --mode=link gcc -std=gnu99 -m32 -g -finline-functions -fno-strict-aliasing -pthread -o opal_wrapper opal_wrapper.o ../../../opal/libopen-pal.la -lrt -lm -lutil libtool: link: gcc -std=gnu99 -m32 -g -finline-functions -fno-strict-aliasing -pthread -o .libs/opal_wrapper opal_wrapper.o ../../../opal/.libs/libopen-pal.so -ldl -lrt -lm -lutil -pthread -Wl,-rpath -Wl,/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/INST/lib ../../../opal/.libs/libopen-pal.so: undefined reference to `udev_new' ../../../opal/.libs/libopen-pal.so: undefined reference to `udev_device_new_from_subsystem_sysname' ../../../opal/.libs/libopen-pal.so: undefined reference to `udev_unref' ../../../opal/.libs/libopen-pal.so: undefined reference to `udev_device_get_property_value' ../../../opal/.libs/libopen-pal.so: undefined reference to `udev_device_unref' collect2: error: ld returned 1 exit status make[2]: *** [opal_wrapper] Error 1 make[2]: Leaving directory `/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/BLD/opal/tools/wrappers' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/phargrov/OMPI/openmpi-2.0.0rc2-linux-ppc32-gcc/BLD/opal' make: *** [all-recursive] Error 1 -- Paul H.
