[MITgcm-support] Bug R_X86_64_PC32

[Martin Losch]

Nataliya,

this is not a bug, but your model dimensions are so large that the  
compiler cannot allocate the fileds on stack. Only last month there  
were postings on this list about that, if you do a search (on http:// 
mitgcm.org/search.html, the source of wisdom (o:) on "relocation  
truncated", you'll get these messages

Depending on your compiler you have to use a different memory model  
(whatever that means). For pgf77 this is done by adding the option "- 
mcmodel=medium" to the compiler flags FFLAGS (in the build_options  
file, whichever you use), other compilers may have different options.
