[MITgcm-support] Re: compiling MITgcm

[Kelvin Richards]

Hi Ed,

Thanks for your swift reply. I suspect it is our gcc and g77 
installation. I can't find the
libg2c.so.0 library. I will get our guys to look into that.

Regarding the Altix, our computer support person, Shinya, was looking 
into that and managed to get quite a bit further than I did. He left 
after I did last night and I will check with him when he gets in later 
today. In the meantime, when I try to run the Makefile I get the error

ld: cannot find -lPEPCOF90

If this is a relatively easy thing to fix let me know. If not I will 
send a full transcript and the Makefile, once I have talked to Shinya.
