[MITgcm-support] Building error on Macbook Pro

[Martin Losch]

Hi Ben,

did you resolve your problem? If not, you seem to have a mismatch of the trailing underscores between your cc and fortran compilers:
>  "_csystemtime_", referenced from:
>       _timer_get_time__ in timers.o
timers.o is generated by fortran and it's subroutines have 2 trailing underscores, while csystime has only one. Check your compilers (and flags). I am using (on a MacBookPro with 2.8GHz IntelCore 2 Duo and OSX 10.6.8)

/usr/local/bin/gfortran -v
Using built-in specs.
COLLECT_GCC=/usr/local/bin/gfortran
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-apple-darwin10.4.0/4.6.0/lto-wrapper
Target: x86_64-apple-darwin10.4.0
Configured with: ../gcc-4.6-20101106/configure --enable-languages=c++,fortran
Thread model: posix
gcc version 4.6.0 20101106 (experimental) (GCC) 

and

/usr/local/bin/gcc -v
Using built-in specs.
COLLECT_GCC=/usr/local/bin/gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-apple-darwin10.4.0/4.6.0/lto-wrapper
Target: x86_64-apple-darwin10.4.0
Configured with: ../gcc-4.6-20101106/configure --enable-languages=c++,fortran
Thread model: posix
gcc version 4.6.0 20101106 (experimental) (GCC) 

and I also modified the default build options file, see attached. I downloaded the compilers from hpc.sourceforge.net (although not the recently updated version which should make the NOOPTFILES-line obsolete).

I did try forcing other suitable genmake2 optfiles while building the makefile but I continue to get this same error during compilation.  I've also tried booting the computer in both 32 and 64 bit modes but no difference there either.  This same error occurs when I tried another tutorial simulation as well (baroclinic gyre tutorial).
