error while loading shared libraries: libgfortran.so.0

[Kamaraju Kusumanchi <kamaraju at gmail dot com>]

I am trying to run an mpi program with mpich2. The program is a
helloworld2.f90 program (attached in the end) compiles fine but when
it is run, gives the following errors.

$mpif90 hello_world2.f90

MPICH2 is compiled with gfortran, gcc.

I am using gcc-snapshot package available in Debian (sid). I can
provide any other additional info if necessary.

I know that MPICH2 is installed properly because when I execute the
cpi program in the examples directory, it runs fine.

I must be doing some trivial mistake here and would be greatful if
someone can point me in the right direction. I have read the user's
guide and installer's guide etc on

http://www-unix.mcs.anl.gov/mpi/mpich2/

but could not see any such problem before. However I saw a similar
problem reported on Intel C++ compiler at

http://support.intel.com/support/performancetools/c/linux/sb/CS-010097.htm



Any ideas are welcome.

thanks
raju
