Take a look at

There has been some discussion about this in the mailing list archive
http://sources.redhat.com/ml/gsl-discuss/ --- nobody is writing
anything.

See the section 'Compatibility with C++' in the manual for some
information.  Basically, it should work from C++ directly as extern
"C" { .. } is present in the header files.

It should work ok with any ANSI C/C++ compiler.  The platforms listed
are ones where it has been tested and reported to work.  There was
some discussion on the list about how to compile with Visual C++
(search for 'visual' on the list archive).

Yes. This is usually possible, but there are dependencies between some
parts. Look at the header files to check.

There are some functions in specfunc/,  e.g. gsl_sf_multiply_err_..,
gsl_sf_exp_err_..., etc. I'm not sure if they are a complete set.

If you'd like to write a C version under the GPL we could consider
including it or pointing people to it. These things are less
convenient in C due to the lack of operator overloading of course.

GSL and (visual) c++

[Andreas Krueger]

Hello,

Today I encountered the GSL - great! I already love it.
It will be sooooo useful for my scientific programming.

However, there are three questions:

a) Is there something similar in c++ ?

b) How do I use it in general c++?
   Why is it platform specific for non-Windows systems?
   (as said on http://sources.redhat.com/gsl/ )
   Isn't c/c++ independent of the OS?
   How can I implement it into my "Visual-C++"-environment?

c) Can I use only parts of it? e.g. statistics only

Many thanks in advance...

ciao,
Andreas

P.S.: I couldn't find any support for "error propagation",
      perhaps you can also implement my "class measure<T>":
