Thank you,
I will try with adding -mlittle-endian option.
Is it correct that I do that by adding at OPTIMIZE in the Makefile?
-------------------------------------------------------------------------------
CC = mpicc
OPTIMIZE = -O3 -Wall -mlittle-endian
GSL_INCL = -I/usr/local/include
GSL_LIBS = -L/usr/local/lib -Wl,"-R /usr/local/lib"
FFTW_INCL= -I/usr/local/include
FFTW_LIBS= -L/usr/local/lib
MPICHLIB = -L/usr/local/lib
#HDF5INCL =
#HDF5LIB = -lhdf5 -lz
endif
-------------------------------------------------------------------------------
FreeBSD 9.0 use "gcc version 4.2.1 20070831 patched [FreeBSD]"
It did not work to add -mlittle-endian like I did, maybe 4.2.1 it to old. I
am now building 4.4, will see how that work.
Best regards,
/Christer
