Unix to Linux Conversion problem

[BlindEagle]

I am fairly new to fortran and i was recently elisted to comvert a unix fortran program to compile and run in a linux environment. Now, the program compiles and runs just fine using f77 on the Unix machine as well as using Compaq Visual Fortran on a windows machine. But when I tranfer the source code to the linux machine and compile it using f77 i get an innumerable amounts of the same error....

>>Argument #60 (named `lnmm') of `bbmain1d' is one type at >>(2) but is some other type at (1) [info -f g77 M GLOBALS]
>>ther_nem_combined.f:18493:
>> subroutine >>bbmain1d(ixm,ixp,iym,iyp,izm,izp,ixs,mul,ias,iasmx

>>ther_nem_combined.f:24972: (continued):
>> call >>bbmain1d(a(iixm),a(iixp),a(iiym),a(iiyp),a(iizm),a(iizp)
>> 2

PLEASE HELP!

try g77 or gfortran instead of f77
