[Nek5000-users] Compiling nek5000 with MPI on Mac.

[nek5000-users at lists.mcs.anl.gov]

Hi, Aleks,

First, I have tried to set F77 = "mpif77" and IFMPI = "false". And the
example works fine.

The result is:
------------------------------------------------------
...
...

#############################################################

#                  Compilation successful!                  #

#############################################################

__TEXT __DATA __OBJC others dec hex

2633728 78450688 0 4295122944 4376207360 104d7a000

---------------------------------------------------------

Then I set:

--------------------------------
#!/bin/bash
# Nek5000 build config file
# (c) 2008,2009,2010 UCHICAGO ARGONNE, LLC

# source path
SOURCE_ROOT="/Users/wenhaowu/Documents/testcases/nek5/trunk/nek"

# Fortran compiler
F77="mpif77"

# C compiler
CC="mpicc"

...

# OPTIONAL SETTINGS
# -----------------

# enable MPI (default true)
#IFMPI="false"

...
----------------------------------

When I try to run "makenek", it still turns out several errors like this:

-----------------------------------
mpicc -c  -O2 -DPTRSIZE8 -DMPI -DLONGINT8 -DUNDERSCORE -DGLOBAL_LONG_LONG
 -DPREFIX=jl_ /Users/wenhaowu/Documents/testcases/nek5/trunk/nek/nek_comm.c
-o obj/nek_comm.o
