"relocation overflow" and "relocation truncated to fit errors" for Fortran application with g77 compiler

[sameer sinha]

My code (FORTRAN 77) successfully compiled on 32 bit Xeon cluster with
8 GB RAM(RHEL platform)
but when
I am using a 64-bit AMD apteron cluster with 8 GB RAM (RHEL platform).
I face "relocation overflow" and "relocation truncated to fit errors"
when I compile big fortran 77 codes using f77/g77 (even with ifort and
pathf95) on it. Though it compiles successfully it cannot assemble or
link the executables. I understand this is because of large arrays or
so. But the executable size is not more than 2GB. so I could not run
my codes with large dimensions.

Can you please tell me what options I can use while compiling thse
kind of codes. Sometimes, ulimit command or -m32 option  worked but
when I run the executable it simply dumps the core. Please suggest me
what can I do to get rid of these problems?.

I am getting this error while compilation
