[Wrf-users] Compiling WRFV3 on i686 - module_dm.o fails

[John Krasting]

Hi Users -

I am now compiling WRF on the i686 platform.  I am using gcc and gfortran
version 4.1.2.  I successfully built NetCDF version 3.6.3 with these
compilers.

My compile of module_dm.F fails.  Here is the output:

rm -f module_dm.o
/home/krasting/WRFV3/tools/standard.exe module_dm.F > module_dm.b

The compile chugs aways for close to 5 minutes before failing.  I tried
removing the -O0 flag and got the same result.

Anyone encounter this problem?  Any tips on how to debug this?

Thanks,
John
