compilation error

[Devasis Bassu]

Hi,

Getting an error trying to compile the code. Am on MacOS Mavericks with OCAML 4.01.0 and find lib 1.4. The output of make is pasted below.

Thanks in advance, Devasis

$ make cd lib/dcg && make ocamlc -c msg.ml ocamlopt -c msg.ml ocamlc -c dcg.ml ocamlopt -c dcg.ml ocamlc -c matcher.ml ocamlopt -c matcher.ml ocamlc -a -o dcg.cma msg.cmo dcg.cmo matcher.cmo ocamlopt -a -o dcg.cmxa msg.cmx dcg.cmx matcher.cmx ocamlc -I +camlp4 camlp4lib.cma -pp camlp4orf -c pa_dcg.ml echo

ocamlfind ocamlc -pp "camlp4o -I lib/dcg -I lib/ipp pa_dcg.cmo pa_ipp.cmo" -w usy -thread -I lib -I lib/dcg -I lib/ipp -c semantics.ml File "semantics.ml", line 212, characters 2-102: Error: The method `reset_modif' has multiple definitions in this object make: *** [semantics.cmo] Error 2 $

One more thing: the first line in the makefile should read OCAMLFIND=<path-to-you-copy-of-ocamlfind>

I have it set as follows OCAMLFIND =ocamlfind

Currently, it points to the binary in a personal directory.

Hi,

thanks for the feedback. The error is only returned since OCaml 4.01, and I use OCaml 4.00.1 so far. I have pushed a new version that should be OK. Tell me.

[Devasis Bassu]

Thanks - that worked!

In Ubuntu problem was in variable LIB_DIR in makefile. It should be set ./lib not ../lib.
