Ocsigenserver installation failed

Hi,
I try to install eliom but the compilation of ocsigenserver failed.
Sys: Debian10
OCaml version 4.05.0

~/$ opam install eliom
return:

Hi,
It seems that you have an old version of Lwt_pool installed.
Also you are using an old version of OCaml. I am not sure it is still supported by all Ocsigen packages.
Try to upgrade to OCaml >= 4.07.

I restart my setting from scratch:
remove & purge ocaml - opam
remove .opam
install opam:

~/$ sudo apt install opam

Upgrade last v. of ocaml:

~/$ opam switch create 4.09.0

~/$ ocaml -version
The OCaml toplevel, version 4.09.0

Now i have this error when i try to install a package:

~/$ opam install eliom
Sorry, no solution found: there seems to be a problem with your request.

No solution found, exiting

Installing with 4.05 seems to work fine for me, with the following solution: https://gist.github.com/Octachron/5fb1cf400d11b0d6435696064055cbf6 (that you can import with

opam switch import name_of_downloaded_gist

)

guimb · October 29, 2019, 2:01pm

So to fix the problem of packages installation:
sudo apt install mccs
opam init --solver=mccs
Then
opam instal eliom

The ocsigenserver is installed; so do I need this eliom packages?

octachron · October 29, 2019, 2:10pm

Note that the fix to this eliom issue is to fix the version of js_of_ocaml-lwt to 3.1.0.

octachron · October 29, 2019, 2:28pm

I forgot that the main js_of_ocaml package needs to be downgraded to 3.1.0 too.

guimb · October 29, 2019, 2:36pm

Done Thanks for your help.

The fix (short way):

Ocaml 4.05 works fine.
Downgrade js_of_ocaml.3.1.0 & js_of_ocaml-lwt.3.1.0
reinstall eliom…

Concerning the solver I suppose its link with Debian 10.

Vincent_Balat · October 29, 2019, 3:18pm

Glad you found a solution. I guess 4.09 is too recent and some dependency has not been upgraded yet.
You don’t need to downgrade js_of_ocaml with more recent versions.

Keep us informed about your progress with Ocsigen.
I recommend to start with Ocsigen Start, which will give you a good overview of what you can do, and read the tutorials before the manuals (documentation is huge).

guimb · October 30, 2019, 10:34am

Thks for help.
No doubt I will come back with tricky questions around Ocaml & Ocsigen…
