In that case you can use `f2py -c ... -lf2c`

Usually Fortran compilers lower the cases of routine names and append
underscore to the names.
If they don't by default then they usually provide switches for that.
For more information, please give answers to the questions below.

Could you give an example session how exactly do you call f2py that
would give undefined symbol errors?
What Fortran and C compilers (vendor and version) are you using?
What Fortran compiler flags are you using?
What is the name of extension module you are building?
