Hi Gerd, I've attached a minimal example that exhibits the problem. Here's my test. Confirm PG'OCaml is not installed. $ godi_list -installed | grep pgocaml (* no output *) $ cd foo (* the unpacked example directory *) $ ocamlbuild foo.cma Finished, 1 target (0 cached) in 00:00:00. + ocamlfind ocamldep -syntax camlp4o -modules foo.ml > foo.ml.depends ocamlfind: When using -syntax, the META variable 'preprocessor' must be set Command exited with code 2. Compilation unsuccessful after building 1 target (0 cached) in 00:00:00. Install PG'OCaml. $ godi_perform -build godi-pgocaml Confirm PG'OCaml is installed. $ godi_list -installed | grep pgocaml godi-pgocaml inst:1.4godi2 Compile again. I now get the correct error about not having a database connection. $ ocamlbuild foo.cma Finished, 0 targets (0 cached) in 00:00:00. + ocamlfind ocamldep -package pgocaml -package pgocaml.syntax -syntax camlp4o -modules foo.ml > foo.ml.depends File "foo.ml", line 1, characters 23-42: Camlp4: Uncaught exception: Unix.Unix_error (20 | CstTag21, "connect", "") Preprocessing error on file foo.ml Command exited with code 2. Compilation unsuccessful after building 1 target (0 cached) in 00:00:00. On Sun, Oct 9, 2011 at 5:02 PM, Gerd Stolpmann <i...@gerd-stolpmann.de>wrote: > I'm a bit surprised.
