In normal operation, OPAM only alters files within ~/.opam. During this initialisation, you can allow OPAM to add information to two other files for best results. You can also make these additions manually if you wish. If you agree, OPAM will modify: - ~/.bash_profile (or a file you specify) to set the right environment variables and to load the auto-completion scripts for your shell (bash) on startup. Specifically, it checks for and appends the following line: . /home/alumno/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true - ~/.ocamlinit to ensure that non-system installations of `ocamlfind` (i.e. those installed by OPAM) will work correctly when running the OCaml toplevel. It does this by adding $OCAML_TOPLEVEL_PATH to the list of include directories. If you choose to not configure your system now, you can either configure OPAM manually (instructions will be displayed) or launch the automatic setup later by running: opam config setup -a Do you want OPAM to modify ~/.bash_profile and ~/.ocamlinit? (default is 'no', use 'f' to name a file other than ~/.bash_profile) [N/y/f] n Global configuration: Updating ~/.opam/opam-init/init.sh Updating ~/.opam/opam-init/init.zsh Updating ~/.opam/opam-init/init.csh Updating ~/.opam/opam-init/init.fish =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 1. To configure OPAM in the current shell session, you need to run: eval `opam config env` 2. To correctly configure OPAM for subsequent use, add the following line to your profile file (for instance ~/.bash_profile): . /home/alumno/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true 3. To avoid issues related to non-system installations of `ocamlfind` add the following lines to ~/.ocamlinit (create it if necessary): let () = try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH") with Not_found -> () ;; =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=Edita
