More important, if GSL becomes hard dependency, it becomes a hard dependency for Inkscape as well.

It should be part of your distribution. It is in ubuntu, for example.

Hi all,
Recent commits made GSL a hard dependency, is that desired?
And more important: where do i get it? inkscape.modevia.com has an old gsl package, is that good enough?
Regards, Johan
I used GSL for finding the roots of a 4th degree polinomial in the nearest point routine for elliptical arc and I'll need of the GSL library again to solve a 5x5 linear system for the elliptical arc fitting problem. So I'd like that GSL becames a hard dependency, but obviously I'm open to alternative solutions. Implementing these tools by myself could be a solution but it wouldn't be a little effort. So if there are real points against making GSL a hard dependency I'd whish to know them as soon as possible.
You can download Windows binaries and developer files from here: http://gnuwin32.sourceforge.net/packages/gsl.htm and this is the gnu home page: http://www.gnu.org/software/gsl/

GSL seems like a huge dependency to pull in just for some root finding and solving of small linear systems. I'd either rip the needed code out of GSL and put it into lib2geom directly, or just find some implementation of those two algorithms elsewhere. They're both standard fodder in numerical computing. Most any textbook on numerics covers those topics, for instance.

I'm not opposed to requiring GSL. In my past experience I've found that the gnuwin32 binaries for GSL do not work with 2geom and inkscape. I do not recall why.
Bob,
Do I remember correctly that you had build GSL binaries once upon a time?

Ah, this is a bad news. I never try to build either 2geom or GSL on windows because I work on a Linux platform. I found the gnuwin32 GSL binaries googling a bit. Johan, have you tried them ?

I tried the package from inkscape.modevia.com and compilation works.

Great! At least we know where to find GSL windows binaries that work with 2geom.
