Re: [Axiom-developer] Nag libraries

[Gernot Hueber]

Hi Waldek, 

I have spent some thoughts in how Axiom can interface external (shared) 
libraries. I have tried this one for a few functions of the Gnu Scientific 
Library (GSL) - the work is unfiniished, due to that there are numerous 
functions.
However, this approach is easily adoptably for any external C library.
Furthermore, some of the NAG related domains will be still requried, 
especially that one, converting Axiom functions to Fortran (actually a 
conversion to C are necessary). 

What do you think which approach is more powerful, reliable, ...?
