add topic interoperability #13

Closed Beliavsky closed 2 years ago

Beliavsky commented 2 years ago

I suggest adding the topic interoperability in the About section.

mohawk2 commented 2 years ago

Thanks for the thought! I'm not a Fortran expert; are you referring to C <-> Fortran interoperability, or something else? Also, I'm not sure what you mean by the "About section", which isn't one of the sections of the POD documentation?

zmughal commented 2 years ago

I believe what @Beliavsky means is add it to the GitHub topics. Sure, I can do that.

zmughal commented 2 years ago

Done! Let me know if there is anything else.

mohawk2 commented 2 years ago

That makes sense!

mohawk2 commented 2 years ago

@Beliavsky This is a bit off-topic, sorry - feel free to ignore if you prefer. PDL supplies two Fortran libraries and builds them if a Fortran compiler is present (a major use for this module, in fact). In order to operate correctly on both 32- and 64-bit platforms, I updated the Slatec and Minuit libraries bundled in PDL. Is there any interest in me contributing those changes to an upstream copy of Slatec / Minuit, if such exists?

d-lamb commented 2 years ago

There is not a meaningful upstream for SLATEC. Last release was in 1993, only two minor corrections since then, last in 1999. I don't think it is currently maintained. GSL was intended to be a replacement. So I'm not sure there's any place to send those SLATEC changes. Minuit seems to be similarly opaque, and largely replaced by an OO C++ interface Minuit2.

mohawk2 commented 2 years ago

That would make sense! Perhaps PDL should have a Minuit2 interface. That does sort of suggest the Minuit interface in PDL could usefully (because of quicker builds and a slightly reduced maintenance burden) be removed?

mohawk2 commented 2 years ago

@Beliavsky What do you think of the fortran-lang organisation hosting Slatec? Do you have comms with the netlib folks at all?

zmughal commented 2 years ago

I see a discussion of porting that functionality into stdlib here https://github.com/fortran-lang/stdlib/issues/179. But nothing about the whole SLATEC library being incorporated as far as I can tell. There has been some work on updating parts of SLATEC to F90 https://people.math.sc.edu/Burkardt/f_src/slatec/slatec.html and here is an update of one specifically on GitHub https://github.com/fortran-lang/fftpack.
