sundialsml's Issues

opam packaging comments

Two comments on opam packaging from having a quick look at the new opam packages.

  1. It is customary and useful to have an opam file at the root of the project sources, from which the opam files submitted to the opam-repository at release time are derived. This source-local package may have a version field indicating the next version, or just dev. This enables package pinning: people that would download the sources and tweak them can easily convince opam to let them install this tweaked version of the package in stead of the default one.
  2. Rather than having depexts field in your package description, it is often useful to separate them in separate conf-* packages that encapsulate a bunch of depexts on many different systems. In your case, sundials is arguably a package-specific dependency (one could create a conf-lapack package but you would be the only user), but there already is a conf-lapack package and it would be better to depend on it rather than list the same depext dependencies. In particular, the package contains a piece of code to detect the presence of the library at build time and it will fail explicitly if it is absent from the system. On the other hand, conf-lapack does not have the lapack depext, so you should probably add it there (by sending a pull request to the opam-repository). The advantage is that it shares the work between packages.

Issues when installing SundialsML on macOS Catalina

I have been using SundialsML before on earlier versions of macOS, but now when I installed opam and sundialsml from scratch on a clean macOS Catalina 10.15.5 installation, I get compilation errors.

First, I installed Sundials via brew (brew install sundials). Then when I run opam install sundialsml I get the following error:

Any ideas what the problem is?

sundials 3.1 homebrew

hi, i tried to install sundialsml on os x. beforehand i installed sundials via homebrew. at various stages, i got error messages:

  • opam depext sundialsml complains about homebrew/science/sundials but that is deprecated in favor of homebrew/sundials.
  • at some point i was able to get opam installation to start. however then no file sundials_config.h could be found so that compliation of sundialsml stopped at the configure stage.

i finally got it to work after downgrading sundials to version 2.7.0_3 using homebrew.

it seems either sundialsml or some installation step on os x is incompatible with sundials 3.1 ?

print functions for the array types?

as a suggestion: for user convenience would it make sense to define print functions e.g. for Sundials.Realarray.t that can be used with #install_printer in the toplevel and with @a in format strings?
