I am trying to link existing, large Fortran code to python. I decided to utilize very good Python-C interoperability and link Fortran code with C wrapper first.
I have a proble with the following typedef:
type, BIND(C) :: type_state
complex*16, dimension (:,:,:,:),allocatable :: g
end type type_state
I have deleted the rest, as there are there a few integers and arrays. According to Intel Compiler manual, and Fortran 2003 specification, derived types may not contain pointer and allocatable arrays (but may fixed size arrays) to be interoperable with C struct contruct. Is there any way to go aroud the problem? Under some conditions this type should be mappable into "extern struct" with appriopriate number of pointers and integers inside it, but I suppose this is poorely portable.
The target machines are simple PCs with at most 2 modern Intel processors, working under linux (red hat, debian or Ubuntu).
