What is the newest version of Core_bench that still works with OCaml 3.12?

[Evgeny Roubinchtein]

Dear, Core developers and users,

Does someone happen to know what is the newest version of Core_bench that (still) works with OCaml 3.12? (assuming it even exists).  I would like to use Core_bench to get some timings, and, for reasons I don't want to go into here, it isn't practical for me to run the code under OCaml 4 (please take it on faith that I do have good reasons).

Thank you in advance!

Best,

Core_bench doesn't appear to be installable on OCaml 3.12.1, unfortunately. You can find out by:

$ opam switch 3.12.1
$ opam install core_bench
The following dependencies couldn't be met:
- core_bench -> fieldslib = 109.20.00
- core_bench -> pa_ounit = 109.53.00 -> type_conv = 109.53.00
- core_bench -> textutils (= 109.36.00 | >= 109.53.00) -> pa_ounit = 109.53.00 -> type_conv = 109.53.00
- core_bench -> textutils (= 109.36.00 | >= 109.53.00) -> core >= 109.36.00
Your request can't be satisfied:
- core>=109.36.00 is not available because your system doesn't comply with ocaml-version >= "4.02.1".
- fieldslib.109.20.00 is not available because it requires OCaml >= 4.00.0.
- type_conv.109.53.00 is not available because it requires OCaml >= 4.00.0.
