Error in automake with AM_YFLAGS

[Paulo J. Matos]

Hello all,

I added to my configure.ac:
AC_ARG_ENABLE([debug-parser],
                             AC_HELP_STRING([--enable-debug-parser],
[enable parser debug (default is NO)]),
                             [case "${enableval}" in
                             yes) debug_parser=true;;
                             no) debug_parser=false;;
                             *) AC_MSG_ERROR(bad value ${enableval}
for --enable-debug-parser);; esac], [debug_parser=false])
AM_CONDITIONAL(DEBUG_PARSER, test x$debug_parser = xtrue)

AC_ARG_ENABLE([debug-lexer],
                            AC_HELP_STRING([--enable-debug-lexer],
[enable lexer debug (default is NO)]),
                            [case "${enableval}" in
                            yes) debug_lexer=true;;
                            no) debug_lexer=false;;
                            *) AC_MSG_ERROR(bad value ${enableval}
for --enable-debug-lexer);; esac], [debug_lexer=false])
AM_CONDITIONAL(DEBUG_LEXER, test x$debug_lexer = xtrue)

And then in Makefile.am:
if DEBUG_PARSER
AM_YFLAGS = -d --debug
else
AM_YFLAGS = -d
endif
if DEBUG_LEXER
AM_LFLAGS = -d -o$(LEX_OUTPUT_ROOT).c -CFa
else
AM_LFLAGS = -o$(LEX_OUTPUT_ROOT).c -CFa
endif

During autoreconf I get:
$ autoreconf
