Thanks for the report. You are right that the interface is wrong, but oddly I have not encountered a problem. I'm not sure what the second argument should be and unfortunately I haven't had the time to dig into it. I will push a fix when I've figured it out.

Hi there,

I'm trying to compile the latest version of GSLL (last commit on master branch dd2e7673) and have a compilation error saying that function "jacobian" is called with one argument whereas it wants exactly two. It happens on the following line:

https://gitlab.common-lisp.net/antik/gsll/blob/master/solve-minimize-fit/nonlinear-least-squares.lisp#L262

and the compiler has the right to complain as with my GSL2 version the signature of the function indeed wants two arguments:

https://gitlab.common-lisp.net/antik/gsll/blob/master/solve-minimize-fit/nonlinear-least-squares.lisp#L150

This seems like an easy to fix bug but I have no idea about the internals of this library.

Could somebody help out?

For now I just exchanged the call (on line L262) of

"(jacobian solver)"

to

"(jacobian solver cov)"

to have some matrix in there but I don't think that this is the right solution.

Thanks in advance!
