Re: [Caml-list] unbound value Parser.main?

[Michael Leary <leary@nwlink.com>]

doh!  the OcamlMakefile... is picky about names.

I've got it like this now:

SOURCES = lexer.mll parser.mly fbot.ml 
RESULT = fbot
LIBS=str

but now getting:

ocamllex.opt lexer.mll
134 states, 7680 transitions, table size 31524 bytes
ocamlyacc  parser.mly
make[1]: Entering directory `/home/leary/dev/ocaml/fbot'
making ._ncdi/parser.di from parser.mli
making ._d/parser.d from parser.ml
making ._d/lexer.d from lexer.ml
making ._d/fbot.d from fbot.ml
make[1]: Leaving directory `/home/leary/dev/ocaml/fbot'
make[1]: Entering directory `/home/leary/dev/ocaml/fbot'
ocamlopt.opt -c       lexer.ml
File "lexer.mll", line 2, characters 0-11:
Unbound module Parser
make[1]: *** [lexer.cmi] Error 2
make[1]: Leaving directory `/home/leary/dev/ocaml/fbot'
make: *** [native-code] Error 2

which seems closer to the problem... :/
