[IPOL discuss] GSL for IPOL [Re: OpenCV and IPOL]

[Tristan]

Hello.

The GSL team has recently released the 1.16 version. According to some 
of developers' discussion on its forum,
it seems that this version is be more compatible with the last microsoft 
compiler Visual Studio :
http://lists.gnu.org/archive/html/bug-gsl/2013-07/msg00030.html

I have not tested its compilation yet on MSCV but conversion scripts are 
available here  :
http://gladman.plushost.co.uk/oldsite/computing/gnu_scientific_library.php

I transmit you the detailed procedure of the 1.15 compilation. 
Principles of 1.16 compilation are similar.
