Hopefully I've CC'd this to everyone who has a package that BuildRequires ocaml-extlib in Fedora. As Andy pointed out in the bug report above, ocaml-extlib has two ways to build it, and upstream recommends building using the "minimal" variant. The difference is that the minimal variant omits certain modules which conflict with OCaml modules found in the standard library or in other packages. Because of the way OCaml modules work, you cannot have a program with two modules with the exact same name even if they come from different packages - instead you should namespace modules, but extlib never did this. The modules that are *removed* by setting minimal=1 are: - Unzip - UChar - UTF8 I looked at the packages in Fedora which BR ocaml-extlib and it looks like nothing uses these modules. Haxe seems to have a bundled copy of extlib with these modules, some renamed, it's not very clear what's going on. So I think there are three plausible options here: (1) Use the minimal=1 flag, since nothing directly in Fedora should be affected. But perhaps external users will care, or I made a mistake in my analysis. (2) Build both extlib variants from single source. (3) Do nothing. Note that the professed aim of extlib upstream is to make itself obsolete by including all the features in the standard library, so one day in the perhaps distant future we will remove ocaml-extlib. Let me know if you have any thoughts.
