For debian packaging the requirement are like this:
- possibility to set the installation dir (as you say), better if we can
do it on cmdline with a parameter to ocamlfind
This parameter is only used to override the compiled default.
the reason is that in the process of doing debian packaging, there is
the need of install the files in a temporary directory relative to the
current dir; so, having such a option is really usefull
- possibility of adding package to the knowledge of ocamlfind, and seems
that is not a problem, we just have to install the files in a dir that
is in the sight of ocamlfind
- have a system wide OCAMLPATH and an user defined OCAMLPATH. We use the
systemwide OCAMLPATH as a default where ocamlfind look to when no user
defined path is specified and we leave to the user the freedom of
install modules wherever he need (also his home dir).
For the system wide OCAMLPATH two choice:
- compiled in ocamlfind (but it is restrictive a lot)
- a configuration file (best choice) like /etc/ocamlfind.conf that
contain a line like "OCAMLPATH=..."
I prefer a configuration file instead of a environment variable
cause there is not a system wide configuration file for environment
variables (e.g. /etc/profile is used by bash but not by tcsh), the
user may override this PATH with env variable OCAMLPATH
So, in practice, two changes to ocamlfind: a cmdline par for overriding
the target installation dir and a configuration file that set OCAMLPATH.
What you think about this ?
