I agree, GSL is useful and very stable. The only question was if it would be usable for people working on Windows. GSL is not written with windows compatibility in mind and the authors do not guarantee it is usable on this platform. There are many blogs and websites explaining how the compilation of GSL on Windows is possible, but they are always specific to a given version of GSL and I was wondering if we could rely on this information for the long term. Tristan did a detailed study of this matter, and if I remember correctly the conclusion was: * The standard C compiler on Windows, MSVC, can not compile the official version of the GSL because of non-standard behaviour of this compiler. * But some tools are available to convert the standard GSL headers to MSVC-compatible headers; these tools are based on Perl. * So it is possible to compile, install and use GSL on Windows; but it is definitely not for beginners. * It would be nice to provide a detailed compilation manual or a precompiled binary version somewhere on <a href="http://ipol.im" target="_blank">ipol.im</a>. So, if there is a consensus on it, I think we could allow GSL as an external library and mention it in the software guidelines. And if someone has the time to prepare a manual or a precompiled version, it's even better, but should not stop us from accepting GSL. -- Nicolas LIMARE - CMLA - ENS Cachan <a href="http://limare.perso.math.cnrs.fr/" target="_blank">http://limare.perso.math.cnrs.fr/</a> IPOL journal <a href="http://www.ipol.im/" target="_blank">http://www.ipol.im/</a> -> image processing, reproducible research, open science -- IPOL - Image Processing On Line - <a href="http://ipol.im/" target="_blank">http://ipol.im/</a> contact <a href="mailto:edit@ipol.im">edit@ipol.im</a> - <a href="http://www.ipol.im/meta/contact/" target="_blank">http://www.ipol.im/meta/contact/</a> news+feeds twitter @IPOL_journal - <a href="http://www.ipol.im/meta/feeds/" target="_blank">http://www.ipol.im/meta/feeds/</a> announces <a href="mailto:announce@list.ipol.im">announce@list.ipol.im</a> - <a href="http://tools.ipol.im/mm/announce/" target="_blank">http://tools.ipol.im/mm/announce/</a> discussions <a href="mailto:discuss@list.ipol.im">discuss@list.ipol.im</a> - <a href="http://tools.ipol.im/mm/discuss/" target="_blank">http://tools.ipol.im/mm/discuss/</a> </blockquote></div>
