There is currently no Ada binding, and you are welcome to create one. You could start with a thin binding to the few subprograms you need, publish it on Sourceforge, Savannah, Tigris or Belios, and invite other people to join in. PS. This topic was discussed on November 1st on this newsgroup; please search the archives if you want to know who else is interested :) PPS. Adrian Wrigley might be willing to publish his few thin bindings under the GPL, as a starting point? -- Ludovic Brenta.

I would think that it would be more useful to translate the library to Ada as a generic package, so any floating type could be used, but of course it would then be necessary to maintain synchronization with the original version. --- Brian

Which may not be such a trivial thing to do: aldar portage # cat sci-libs/gsl/ChangeLog|grep \* *gsl-1.8 (11 Apr 2006) *gsl-1.7 (14 Oct 2005) *gsl-1.6 (16 Jan 2005) *gsl-1.4 (28 Dec 2004) *gsl-1.4 (18 Nov 2003) *gsl-1.1.1 (12 Jun 2003) *gsl-1.3 (14 Feb 2003) *gsl-1.2 (06 Aug 2002) *gsl-1.0 (1 Feb 2002) Expect two new releases per year on average. If anybody is ready to undertake this, sure, but I think the more realistic aim would be to have a binding.. George

Brian's comment suggests translating the package in order to make the floating type generic(?). Surely this isn't necessary? The most you would want is a thick binding which chose the GSL code for single or double precision according to the precision of the generic parameter. Gnat *may* be able to optimise the instance to eliminate any dead code. And since my name was mentioned higher up the thread, I'm not planning on digging out the few bindings that I made for public use - they were coded without much thought, just to try out GSL in my application. I didn't use them in the end because the routines didn't meet my needs at the time. Perhaps in the future, I will try again, because my needs and the GSL have changed and expanded significantly. A decent binding would probably best work out if someone in the Ada community was actually using GSL in Ada regularly, since they would have working, maintained code as a base. If that's where my coding is likely to go, I'll seriously consider putting it on a public license from the start. -- Adrian |
