[MITgcm-support] optfile

[Martin Losch]

Elja,

the (incomplete) messages that you provide tell me that genmake2 to  
trying to guess your environment and uses some defaults. These  
defaults (or the guess) do not work in your case. In order to make  
things work you need to know
1. your platform+operating system (what does "uname -a" give  you?)
2. the compiler that is available/that you want to use (including the  
path to it and to possible libraries that may be necessary, talk to  
your system administrator).
Based on that information, you can choose an optfile in the tools/ 
build_options/ directory as a strating point (as Nikolay suggested),  
copy this file to a new name and adapt it to your needs.

If you need further help, please make all of the output (stdout and  
error) of "genmake2", "make depend", and "make" available.
