Problem installing #637

Closed gantsevdenis closed 3 years ago

gantsevdenis commented 3 years ago

(Not sure if I should create an issue here, or contact distro maintainers) Trying to install ocsigen-start requires to downgrade my ocaml from 4.13.1 to 4.11.2. Which I also tried, but failed with a compilation error (related to ocaml 4.11.2 installation, not ocsigen-start itself):

[ERROR] The compilation of ocaml-base-compiler.4.11.2 failed at "make -j3 world.opt".

Is ocsigen-start supposed to work with the most recent Ocaml?

Hello @gantsevdenis,

Yes, it is supposed to work with the latest version of OCaml (4.13.1). I have just installed it on Debian 11.1 with opam 2.1.0 on a fresh local swtich:

mkdir -p /tmp/test-ocsigen-start
cd /tmp/test-ocsigen-start
opam update
opam switch --empty create .
opam install ocsigen-start

thanks @ilankri , this worked (with small hack of adding export CHECK_IF_PREINSTALLED=false; ..., otherwise ocamlbuild breaks, even if I already have exactly the same version installed globally). It looks like my global installation is broken somehow, I confirm it installs correctly from empty environment with Ocaml 4.13.1 Thanks for your help!
