error: duplicate symbol: MAIN

[Soniya]

i compiled Fortran code for dll and i am getting error: duplicate symbol: MAIN. 

i am using only one main function. what could be the issue? can anyone help into it?

Sounds like you have two files or procedures named "PROGRAM"

Or, you are linking with a C/C++/other language main entry.

A source code for a dll must only contains functions or subroutines (or data). So if there is a program statement or code not embedded in subroutine/end subroutine or function/end function sections, it will produce an error.

Note, a DLL is a library. It does not have a PROGRAM procedure.
