I'm building from todays svn co on an x86_64 centos 5 Linux 2.6.18-128.1.10.el5 #1 SMP using
m4 (GNU M4) 1.4.13 automake (GNU automake) 1.11 autoconf (GNU Autoconf) 2.64 ltmain.sh (GNU libtool) 2.2.6 gcc (GCC) 4.3.2 and configured with ../configure --prefix=$HOME/openmpi --srcdir=.. --disable-mpi-f77 --disable-mpi-f90 and get libtool: link: gcc -O3 -DNDEBUG -finline-functions -fno-strict-aliasing -pthread -fvisibility=hidden -o opal_wrapper opal_wrapper.o ../../../opal/.libs/libopen-pal.a -ldl -lnsl -lutil -lm -pthread ../../../opal/.libs/libopen-pal.a(libltdlc_la-ltdl.o): In function `lt_dlinit': ltdl.c:(.text+0x10d3): undefined reference to `lt_libltdlc_LTX_preloaded_symbols' Is anyone familiar with this or what to do about it? If I try to avoid with ../configure --prefix=$HOME/openmpi --srcdir=.. --disable-mpi-f77 --disable-mpi-f90 --disable-dlopen I 'make -j 4' successfully but during 'make install' get /bin/sh ../../../libtool --mode=install /usr/bin/install -c opal_wrapper '/home/hines/openmpi/bin' ./opal_wrapper: line 1: ELF: command not found libtool: install: invalid libtool wrapper script `opal_wrapper' Hints on how to build on this machine are greatly welcome. I had the same problems when using openmpi-1.3.3.tar.gz and my normal development environment (less recent m4 and autotools, and gcc-4.1.2) Thanks, Michael
