Fortran undefined symbol f90

    I have an error when I try to execute my python program which uses a fortran subroutine (which call date_and_time function) :
    "undefined symbol: G77_date_and_time_0"

    Do you know how can I fix this issue?
    Thank you very much!

    It looks like a compiler error. Are you trying to force a g95 compile that uses g77 calls? It seems like it may be a compiler-specific function that is causing the problem.
