Hello list,

I have learned that dune is the build manager which should be used for ocaml packages. I am currently using ocamlbuild and tried to switch to dune.

In order to build documentation with dune I had to install odoc. So I tried to install odoc via opam install odoc. However opam wanted to downgrade a lot of packages in order to install odoc and finally screwed up my installation.

I could recover from this situation by opam upgrade. However I don’t get a working installation with odoc. Isn’t there a version of odoc which is compatible with other libraries in their current version? If not I probably cannot use dune as a build manager.

Thanks for any hint.

Regards
Helmut

Did you `opam udpate` before installing `odoc` ? As far as I can see odoc 1.4.0 has no upper constraints so it seems a bit strange to see *downgrades* (unless those are in its recursive deps).

If that is the case could you please indicate which dependency is problematic. 

Best,

Daniel

No. I did ‘opam upgrade’ after my failed trial to install ‘odoc’ with all the downgrades.

After `opam upgrade` I did `opam update` and I have tried another `install odoc` and it succeeded.

I don’t understand this. Can you explain?

Regards
Helmut

`opam update` fetches the latest package definitions from the opam repository. `opam upgrade` upgrades your packages to their latest version. Invoke the commands with `--help` for more information. 

I suspect you didn't have the definition for opam 1.4.0 before you `opam update`d. 

Best,

Well re-reading this sentence I understand it might be confusing. `opam upgrade`, upgrades packages to their latest version according to the definitions you have *locally*.
