Query About Flex Usage

[Ramprasad B]

Hi all,

This is my first post to this mailing list.
I have one simple query / doubt about generating a lex scanner generator.
I am doing these steps -

# flex parser.l
# gcc lex.yy.c

but after this i get some errors as

/tmp/ccAKLeZj.o(.text+0x1790): In function `yylex':
: undefined reference to `yywrap'
/tmp/ccAKLeZj.o(.text+0x1d72): In function `input':
: undefined reference to `yywrap'
collect2: ld returned 1 exit status

do wehave to link some library ?
Since i did this when i was at my engg college.
But it is after 1 1/2 year so, i have forgotten :(

Can anyone giude me ?






Thanks and Regards,
