[MITgcm-support] teething.. genmake2 with gfortran

[jschwarz at awi-bremerhaven.de]

Hi all,

thanks for the first tip regarding cvs with an IP address - cvs still won't work on this network, but thanks anyway.

I now have a problem running genmake2: I get the feeling it's really trivial but can't find the problem..  
to avoid confusion, here is the exact command issued and resulting message:

GENMAKE :

A program for GENerating MAKEfiles for the MITgcm project.  For a
quick list of options, use "genmake -h" or for more detail see:

this was using the optfile for gfortran.  In case the optfile was a problem, i also tried without the optfile to see if genmake could find it's own way around, and got:

ln should work, since 'which ln' and 'ln --help' give information.  There shouldn't be a problem
with permissions as i'm currently running as root (i know it's bad - long story):  ./test does exist in the 
/verification/exp2 directory and it's write permissions are rwxr-xr-x.  
None of the mitgcm files have been changed except for renaming the results files for exp2.

Hopefully some kind soul will recognise this as a simple thing to remedy!   
As an aside, where should ROOTFILE be specified?

In hope,
jill.
