Are you using Bison?

The answer is just a google search away, http://www.ibm.com/support/knowledgecenter/ssw_aix_61/com.ibm.aix.cmds6/yacc.htm

1 solution

Since you're using Bison, have a look at Bison 3.0.4: Bison Options[^]
Quote:
-d
This is the same as --defines except -d does not accept a file argument since POSIX Yacc requires that -d can be bundled with other short options.

Quote:
-v
--verbose
Pretend that %verbose was specified, i.e., write an extra output file containing verbose descriptions of the grammar and parser. See Decl Summary.
