Hi,
You have to update the ldcache each time you add some .so files to the
directories it refers to. If you don't, any .so file you added since
system bootup will not be found (even if they are in the filesystem).
This is made by running ldconfig as root. If this does not solve your
problem, please check that /usr/local/lib appears in the output of
ldconfig -p.
If it does not, you have to add this directory to /etc/ld.so.conf, or
to the LD_LIBRARY_PATH shell variable, or to use the --enable-mpirun-
prefix-by-default option in the Open MPI configure.
Hope that helps,
Aurelien

Dear OpenMPI group:
I am sorry about this newbie question, but, I was not able to find the
answer so far.
I compiled OpenMPI-1.2.5 from source on a OpenSUSE 10.3 64 bit OS.
Configure and installation seemed fine (using prefix=/usr/local). I
installed openmpi as root. But, when I ran a quick test program, I
got
the following error:
saturn:~/openmpi/openmpi-1.2.5 # mpicc -o hello_mpi.c hello_mpi.c
mpicc: error while loading shared libraries: libopen-pal.so.0: cannot
open shared object file: No such file or directory
saturn:~/openmpi/openmpi-1.2.5 #
But, I found libopen-pal.so.0 in /usr/local/lib. How to get
mpicc/mpif90 wraper to find libopen-pal.so in the correct directoy?
Also, on another workstation (OpenSUSE 10.2 64 bit OS), I installed
the
openmpi-1.2.2 rpm (and openmpi-1.2.2-devel rpm). Libopen-pal.so was
laced in /usr/lib64/mpi/gcc/openmpi/lib64. I has the same problem
when
executing mpicc/mpif90.
Can someone shed some light on this? Thanks!
Pei
