Undefined symbols for architecture x86_64

[Felipe Pimenta]

Dear Steve, Arjen and Dominique,

Thank you for your reply. The functions like " fjul_dutcoftai" are
part of a "julian" library, necessary for the model.

I've tried to compile the library alone, but the error continues, with
or without -m32 and -m64.

It seems the library was created for f77, and is no longer supported
(http://pds-rings.seti.org/toolkits/).

I've tried with -fno-leading-underscore too, but it didn't work.

Regards,

Felipe
