Hello,
Inspired by the recent `Accelerating compilation' discussion, I have installed the *.opt version of the compilers
apt-get install ocaml-native-compilers
What is the right way to invoke, say ocamlc.opt via ocamlfind?
ocamlfind c -c -g -o foo.cmi foo.mli
works but I guess ocamlfind invokes here ocamlc (not ocamlc.opt, even if it is installed).
Attempts like these:
ocamlfind c.opt -c -g -o foo.cmi foo.mli
ocamlfind ocamlc.opt -c -g -o foo.cmi foo.mli
fail because "c.opt" and "ocamlc.opt" are not recognized as ocamlfind commands.

Don't know if it's the right way. But this should work:
Do

This should indicate you the location of `findlib.conf` in which you can set the tools to invoke e.g.:
> cat /Users/dbuenzli/.opam/4.00.1/lib/findlib.conf
destdir="/Users/dbuenzli/.opam/4.00.1/lib"
path="/Users/dbuenzli/.opam/4.00.1/lib"
ocamlc="ocamlc.opt"
ocamlopt="ocamlopt.opt"
ocamldep="ocamldep.opt"
ocamldoc="ocamldoc.opt">
N.B. this happened to me automatically, so maybe if you install the opt compiler first and then ocamlfind, its install procedure is able to infer the right findlib.conf.
Best,
Daniel

You can set the OCAMLFIND_COMMANDS environment variable, for example
to use ocamloptp instead of ocamlopt and ocamldoc.opt instead of
ocamldoc:
export OCAMLFIND_COMMANDS="ocamlopt=ocamloptp,ocamldoc=ocamldoc.opt"
See "man ocamlfind".

You can do more than guessing:
$ ocamlfind ocamlc -verbose foo.ml
Effective set of compiler predicates: autolink,byte
+ ocamlc.opt -verbose foo.ml
