Hello,
On the following example (in p4.ml):
type t = Foo [@@attribute blabla]
the following command fails due to camlp4 not handling [@@ attributes:
$ ocamlfind ocamlc -package js_of_ocaml.syntax -syntax camlp4o p4.ml
File "p4.ml", line 1, characters 9-12:
Parse error: [semi] expected after [str_item] (in [implem])
File "p4.ml", line 1:
Error: Error while running external preprocessor
Command line: camlp4 '-I' '/home/guesdon/.opam/4.02.1/lib/ocaml/camlp4'
'-I' '/home/guesdon/.opam/4.02.1/lib/js_of_ocaml' '-parser' 'o'
'-parser' 'op' '-printer' 'p' 'pa_js.cmo' 'p4.ml' > /tmp/ocamlpp1dd80a
Is there a special invocation of camlp4 to make it accept the [@@
syntax ?
