undefined symbol f90

[Dreyliciouss]

Hello,
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!

Probably that routine only works if you use the G77 compiler.
Date and time routines are, as far as I know, always compiler dependent, so look up what it should be for the compiler you're using.
