When we need to develop with Ocaml4, we have to recompile + all the dependencies, but this implies to install them for the whole + system. But we can use a local repository with some findlib configuration. + +Findlib is now a required tool for an Ocaml project compilation. Each +application uses now findlib for searching the dependencies, and the linking +phase. + +We first need to create a local configuration in wich we write where to find +the packages : + + +.. code-block:: bash + + destdir="/home/chimrod/ocaml/packages/" + path="/home/chimrod/ocaml/packages/:/usr/local/lib/ocaml/4.00.1:/usr/lib/ocaml:/usr/lib/ocaml/METAS" + +:destdir: is the path where we want to install the newly compiled packages. +:path: is the path list where to find the packages. + +Of course, you need to replace `/home/chimrod/` by your own installation path. +It must be an absolute path. + +The path to this file can be saved with the shell environnement ; we just need +to reference it in the `.bashrc` file : + +.. code-block:: bash + + export OCAMLFIND_CONF=/home/chimrod/ocaml/ocamlfind.conf + +That's now : each new package will now be installed in your packages directory, +and the compilation will also look for this path for the required +dependencies : you do not have to install the packages as root anymore. -- cgit v1.2.3
