Re: [Help-gsl] Compiling & Testing New Interpolation Type

[Jean-François Caron]

Oh my god, I just noticed that I was trying to use version 1.6 all along, not 
1.16!  I finally noticed when I tried using the same grep commands as Dave 
Allured to summarize the tests, but zero lines from my test log were matching, 
so I looked more closely.  1.6 doesn’t have DARWIN86 as one of the ieee-utils 
options, hence why stuff wasn’t working.

Not to excuse my lack of attention/stupidity, but on the main GSL page it says 
in text that the current version is 1.16, but the download link goes to a plain 
index page that includes tons of versions - including future versions that are 
probably not expected to work.  Is it possible to add a single link to the 
current version on the main page, or in the FTP listing, have a duplicate entry 
for 1.16 which is explicitly called CURRENT or something?  

When I use 1.16 everything works out of the box.  Sorry for the noise.  (1.6 
did work out of the box on an Ubuntu 12 machine that I tried).

My original problem was that I wanted to add an interpolation type to GSL.  
Specifically I want monotonic cubic-splines following the description in 
Steffen (1990): http://adsabs.harvard.edu/full/1990A%26A...239..443S

I have successfully written a steffen.c file, modelled after akima.c.  It 
compiles and seems to do the interpolation correctly with my basic 
(non-automated) tests.  I am wondering now what are the steps to trying to get 
my enhancement included in gsl itself?  Things like code review, style 
checking, etc.  I’ve never contributed actual code to an open-source project 
before, so I might need some hand-holding.  Should I start a new thread about 
this?

I read somewhere that GSL is considered “feature complete”, but I’ve seen other 
people asking for monotonic interpolation from GSL before, and it’s just a new 
9407 byte file and some trivial additions to gsl_interp.h and the configuration 
files.  I hope it’s an appropriate (and welcome) addition to GSL.
