[MITgcm-support] Problem with MPI (cannot find -lmpi)

[Abbas Dorostkar]

Dear all,

I try to compile MITgcm with -mpi option on my Opteron machine with RedHat
Linux. The MPI environment (MPICH2) is tested by a simple "hello world"
program. However, I get this error message:

 

-L/usr/local/netcdf4/lib -L/usr/local/lib -lmpi

/usr/bin/ld: cannot find -lmpi

collect2: ld returned 1 exit status

make: *** [mitgcmuv] Error 1

 

===  Checking system libraries  ===

  Do we have the system() command using /usr/local/bin/mpif77...  yes

  Do we have the fdate() command using /usr/local/bin/mpif77...  yes

  Do we have the etime() command using /usr/local/bin/mpif77...  yes

  Can we call simple C routines (here, "cloc()") using
/usr/local/bin/mpif77...  yes

  Can we unlimit the stack size using /usr/local/bin/mpif77...  yes

  Can we register a signal handler using /usr/local/bin/mpif77...  yes

  Can we use stat() through C calls...  yes

  Can we create NetCDF-enabled binaries...  no

 

The opt file I use is as follows:

 

#!/bin/bash

#

FC='/usr/local/bin/mpif77'

CC='/usr/local/bin/mpicc'

DEFINES='-DALLOW_USE_MPI -DALWAYS_USE_MPI -D_BYTESWAPIO -DWORDLENGTH=4'

LIBS='-L/usr/local/netcdf4/lib -L/usr/local/lib -lmpi'

INCLUDES='-I/usr/local/netcdf4/include -I/usr/local/include'

CPP='/usr/bin/cpp -traditional -P'

NOOPTFLAGS='-O0'

#MAKEDEPEND=/usr/X11R6/bin/gccmakedep

#MAKEDEPEND=/usr/X11R6/bin/makedepend

#  For IEEE, use the "-ffloat-store" option

if test "x$IEEE" = x ; then

    FFLAGS='-Wimplicit -Wunused -Wuninitialized'

    FOPTIM='-O3 -funroll-loops'

else

    FFLAGS='-Wimplicit -Wunused -ffloat-store'

    FOPTIM='-O0 '

fi

 

I am not sure If something is wrong with my opfile. It would be great If I
could have your ideas.
Thanks very much

Abbas
