Error: Conflict between the following libraries:

- "incr_dom" in /Users/boris/.opam/ocsigen/lib/incr_dom
    -> required by library "incr_dom_widgets" in /Users/boris/.opam/ocsigen/lib/incr_dom_widgets
This is not allowed.

Here are the lib versions I have installed:

incr_dom                            v0.11.0  A library for building dynamic weba
incr_dom_widgets                    v0.11.0  A library of libraries and widgets 
incr_map                            v0.11.0  Helpers for incremental operations 
incr_select                         v0.11.0  Handling of large set of incrementa
incremental                         v0.11.0  Library for incremental computation
incremental_kernel                  v0.11.1  Library for incremental computation

Yes, that's a known issue. If you want to build the examples, you have to create a single dune workspace containing incr_dom and its transitive dependencies. The duniverse tool may be helpful for that

Closing due to how old the issue is. If you still have problems getting it installed, please feel free to re-open or create a new issue.
