Hello all,


I am interesting in compiling the PatoLine typesetting system on some 
Ubuntu 20.04 desktop

(either Intel Xeon Silver 4114 at work, or AMD Ryzen Threadripper 2970WX 
at home; with at least 64Gbytes of RAM, and plenty of disk space)

PatoLine is on https://github.com/patoline/patoline

I would like to use a rather recent Ocaml (4.08 or newer)

With the git commit 3dcd41fdff6489 of PatoLine I am getting

rimski% opam switch 4.05.0
[ERROR] No switch 4.05.0 is currently installed. Did you mean 'opam 
switch create
         4.05.0'?
         Installed switches are:
           - default

Thanks for help

Hi Basile,

I think that the error you get comes from a transition from opam1 (used in
the Patoline webpage for instructions, I guess) to opam2, which changed the
"opam switch" behavior to stop installing a new switch explicitly. The
command recommended in the error message, "opam switch create 4.05.0", will
do the equivalent of the README's command, and get you a 4.05.0 switch. You
should be able to build Patoline there, assuming the dependency bounds have
not bitrotted away.

Getting Patoline to work on a more recent OCaml version may be very easy
(just installing it in a newer switch) or very hard, depending on the
change-robustness and maintenance level of its codebase and various
dependencies. You cannot tell without trying.

Looking at the "issues" list suggests that Patoline is intermittently
maintained by Rodolphe Lepigre, so I think you should get help if you open
an issue on the repository to report on any further trouble installing
Patoline, using either 4.05 or a more recent version.
