[MITgcm-support] optfile

[Elja Huibregtse]

Dear all,

I am trying to set up the cube-sphere integration (with sea ice on the cs32 grid) on a supercomputer. During the genmake2-step, I get the output:
- The platform appears to be: linux_ppc64,
- Error: can't read OPTFILE="../tools/build_options/linux_ppc64_gfortran"

Because I don't have this file, I was advised to use the following file as optfile:
==================
FC=xlf_r
DEFINES='-DWORDLENGTH=4'
CPP='cpp  -traditional -P'
NOOPTFLAGS='-O0'
MAKEDEPEND=/usr/X11R6/bin/makedepend
FFLAGS='-O3 -qstrict -qarch=auto -qtune=auto'
==================

Applying this file does not seem to work, because the next errors appear during the make-step:
(this is only the last part of the error list):

==================
: undefined reference to `.barrier'
write_state.o(.text+0x214): In function `.write_state':
: undefined reference to `.write_fld_xy_rl'
write_state.o(.text+0x300): In function `.write_state':
: undefined reference to `.write_fld_xy_rl'
write_state.o(.text+0x30c): In function `.write_state':
: undefined reference to `.barrier'
make: *** [mitgcmuv] Error 1
==================


Does someone know what goes wrong and how I have to fix it? 
Does someone have the optfile "linux_ppc64_gfortran"? 

Thanks a lot!
Elja
