I don't understand what is wrong with Ocamlfind. Does someone can help
me ?

echo "value store buf s = do { Buffer.add_string buf s ; buf } ;" >
test.ml
ocamlc -o test -pp "camlp4r" -I +camlp4 camlp4lib.cma ./test.ml
ocamlfind ocamlc -o test -package "camlp4" -linkpkg  -syntax
"camlp4r" ./test.ml
File "./test.ml", line 1, characters 16-17:
Parse error: [expr] expected after [infix operator (level 0) (comparison
operators, and some others)] (in [expr])
Preprocessor error

I don't understand the subtleties of the "-syntax" option, but using
"-pp camlp4r" instead works fine :
Besides, the camlp4 package isn't necessary if your code doesn't use
any of the camlp4 libraries (or quotations/whatever).

$ ocamlfind ocamlc -o test -pp camlp4r -linkpkg ./test.ml

It's useful to add the -verbose option (after ocamlc) to see what
options are passed to camlp4. In this case it's getting the -rp
option, which is apparently
(http://brion.inria.fr/gallium/index.php/Using_Camlp4) the extension
for writing parsers in the revised syntax. Not sure why that breaks
your program, or why Ocamlfind includes it with -syntax camlp4r.
