Hello,
I am trying to install 'js_of_ocaml' with 'opam' and run into some
problems. It seems that the ocaml compile cannot compile the 'lwt' package.
$opam list
Installed packages for system:
base-unix base Unix library distributed with the OCaml compiler
camlp4 4.02.0+system Camlp4 is a system for writing extensible
parsers for programming languages
cmdliner 0.9.5 Declarative definition of command line
interfaces for OCaml
menhir 20140422 LR(1) parser generator
ocamlfind 1.5.3 A library manager for OCaml
ppx_tools 0.99.1 Tools for authors of ppx rewriters and other
syntactic tools
opam install js_of_ocaml
The following actions will be performed:
- install lwt.2.4.6 [required by js_of_ocaml]
- install js_of_ocaml.2.5
2 to install | 0 to reinstall | 0 to upgrade | 0 to downgrade | 0 to remove

Can anybody help (or if this list is not the right location to ask can

I have now 'lwt' and 'js_of_ocaml' successfully installed on the system switch. I gues it does not make sense to have the opam switch of 4.01 any longer.

Is there a way to find all external dependancies list ? 'opam install -e debian <package>' should print a list of all external dependencies to install on Debian. You can try other distro instead of Debian, but not all opam packages have entries for all distributions. Best regards, --Edwin ^ permalink raw reply [flat|nested] 19+ messages in thread

The command sequence you proposed worked successfully. However can you explain to me what I have now. I think I have now two versions of the ocaml compiler installed, one system wide (4.02.0) and one installed by opam (4.01.0). If I use a fresh shell I still get version 4.02 until I issue the 'eval' command to get the new paths. If I try to switch back to 4.02 opam tries to install 4.02 from scratch, i.e. it does not use the system installation. Is there any possibility to switch back to the system installation in the same shell or do I need to use a fresh shell? I still feel uncomfortable because I don't know why the installation of 'lwt' fails with my system installation of ocaml.

You could run 4.02.1 from OPAM, that has some nice features :-) > Is there any possibility to switch back to the system installation in > the same shell or do I need to use a fresh shell? opam switch system And then do the eval-dance :-) > I still feel uncomfortable because I don't know why the installation > of 'lwt' fails with my system installation of ocaml. Im my experience, the Arch Linux ocaml/camlp4 packages are busted, I filed a bug but nothing happened: <https://bugs.archlinux.org/task/41907?dev=162> (Also, keep in mind to switch to the system compiler when building packages from AUR, because having the OPAM compiler in the path messes things up). regards, Marek ^ permalink raw reply [flat|nested] 19+ messages in thread
