Re: New License/Exception Request

J Lovejoy

HI Camille,

We discussed this on the legal call today and would like to add this exception but discovered a glitch. The exception text does not indicate a version of LGPL, but includes the language:

“. . . and distribute that executable file under terms of your choice, without any of the additional requirements listed in clause 6 of the GNU Library General Public License. By "a publicly distributed version of the Library", we mean either the unmodified Library as distributed by INRIA, or a modified version of the Library that is distributed under the conditions defined in clause 3 of the GNU Library General Public License.”

Note the references to clause 6 and clause 3, which directly align with LGPL-2.0 and LGPL-2.1. Sure enough, it is LGP-2.0 that is provided on and most of the projects (I did not look at all) in the OCaml Github account use the exception with either LGPL-2.0 or LGPL-2.1

However, at least two projects in the OCaml Github account use the same exception with LGPL-3.0, which sort of breaks the exception as it is then referring to a different clause 6 and 3 - see: and

We wondered if this was a mistake or if there were plans to update the exception. If the latter, then we would be inclined to add both versions of the exception, but this could then impact the naming convention (e.g., we’d want to use version numbers in the exception or some other way to indicate the difference.)

Are involved enough with the project to raise this? Otherwise, I’m happy to reach out to them directly. Let me know your thoughts.
