[Gsll-devel] nonlinear fit test

[Mirko Vukovic]

I am trying to run gsll on clisp which is running on cygwin & windows.
 It compiles and loads OK.

I am trying to run the nonlinear fit example, and following the
instructions in the comments at the end of the file.
> (nlls-setup) ;works OK

> (solve-nonlinear-least-squares-example)
gives an error:
FFI::FOREIGN-CALL-OUT: 0 connot be converted to foreign type DOUBLE-FLOAT.

By commenting out pieces of the code, it looks that the statement
...(fit (nonlinear-fdffit
	       *levenberg-marquardt*
	       *number-of-observations*
	       *number-of-parameters*
	       exponential-residual
	       init)) ...
is the one that causes the error.  I was unable to dig deeper.

Any thoughts where the problem may be?

Thanks,

Mirko
