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:

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

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!
