In order to be able to use it we had to make the corrections you will find in the attached patch. They fall into 5 categories: 1) namespace errors whereby some std:: qualifications were missing; 2) namespace errors when compiling (as we have to) with FILIB_NAMESPACES defined; 3) incorrect uses of abs() (an int -> int function) instead of fabs() (double -> double); 4) undefined type `Complex'; 5) unused variables (causing annoying warnings). We are now using the revised beta version. However, we could not disable our wrapper around the pow() function, since CoStLy still throws an exception for invocations like, e.g., pow(([-0.5, -0.5],[0, 0]), ([-1, -1],[0, 0])). Do you plan to address also this case?
