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: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!Gaya
