Hi all -
I'm having a bit of an issue with my library paths and mpi that I can't
quite seem to resolve.
If I run from host-0:
mpirun -np 4 -host host-0 myprogram
I have no problems, but if I run
mpirun -np 4 -host host-1 myprogram
I get an error like this:
error while loading shared libraries: libSGUL.so: cannot open shared object
file: No such file or directory
I can see that it can't find two of my shared library files when I execute
this:
mpirun -np 1 -host host-1 ldd myprogram
linux-gate.so.1 => (0xb7f48000)
libSGUL.so => not found
libguile.so.12 => /usr/lib/libguile.so.12 (0xb7e96000)

/lib/ld-linux.so.2 (0xb7f49000)
linux-gate.so.1 => (0xb7f23000)
If I run the following, however, I see that my LD_LIBRARY_PATH is correct:
mpirun -np 1 -host burn-0 echo $LD_LIBRARY_PATH
/usr/local/lib32:/home/budge/local/lib:/home/budge/projects/mgi_tony/build/lib
For now I've had to resort to making mpi run a wrapper script which sets my
LD_LIBRARY_PATH, but naturally this isn't ideal. Does anyone have an idea
what this is or how I can fix it?
Thanks,
Brian
