Hi,
The system is
SunOS newton 5.10 Generic_137111-01 sun4u sparc SUNW,Sun-Fire-15000
and I am using the fortran compiler from sun. I have written the
following config.h file for sunOS
MATH_DEFINES =
MATH_LIBS =
FFT_DEFINES = -DPUBFFT
FFT_INCLUDE =
FFT_LIBS =
NETCDF_HOME =
NETCDF_DEFINES =
NETCDF_MOD =
NETCDF_LIBS =
#DIRFRC_DEFINES = -DDIRFRC_EFS -DDIRFRC_NOVEC
CPP = /lib/cpp
NFLAGS=-xlic_lib=sunperf
##CPPFLAGS = -P
#F90_DEFINES = -DFFTLOADBAL_2PROC
PREPROCFLAGS = -DMPI -I/opt/SUNWhpc/include
F90 = mpf90
#MODULE_SUFFIX = mod
#F90FLAGS = -c -auto
#F90_OPT_DBG = -g -traceback
F90_OPT_LO = -c -O1 $NFLAGS
F90_OPT_MED = -c -O2 $NFLAGS
#F90_OPT_HI = -c -fast $NFLAGS
F90_OPT_HI = -g -c -fast -ftrap=%none -xlic_lib=sunperf
#F90_OPT_HI = -c -fast -xlic_lib=sunperf
F90_OPT_DFLT = $(F90_OPT_HI)
OPT_LO = "mpf90 -c -O1 $NFLAGS"
OPT_MED = "mpf90 -c -O2 $NFLAGS"
#OPT_HI = "mpf90 -c -fast $NFLAGS"
OPT_HI = "mpf90 -c -fast -xlic_lib=sunperf"
OPT_EW_PAIRLIST = "$OPT_MED"
CC = mpcc
CFLAGS = -fast $NFLAGS
LOAD = mpf90
LOADFLAGS =
LOADLIBS = -g -ftrap=%none -L/opt/SS12/SUNWspro/lib/ -xlic_lib=sunperf
-lmpi -fast
#LOADLIBS = -g -L/opt/SS12/SUNWspro/lib/ -xlic_lib=sunperf -lmpi -fast
#LOADLIBS = "-L/opt/SS12/SUNWspro/lib/ -xlic_lib=sunperf -lmvec -fast"
Any suggestions to fix the problem appreciated - thanks in advance
With kind regards
