What is the difference between these two opam switches:
ocaml-base-compiler 4.14.0 Official release 4.14.0
ocaml-variants 4.14.0+options Official release of OCaml 4.14.0
and will it affect the ability to install libraries?
Hi,
The difference is described in this post. In a nutshell, opam-base-compiler is a “vanilla” compiler, while the +options compiler can be reconfigured without recreating the switch. For example, on a switch based on a +options compiler, it’s possible to opam install ocaml-option-afl to make the compiler use AFL instrumentation (which will also rebuild all packages in it).
Most libraries are compatible with all options, but some packages are incompatible with a certain one.
