libpcap-1.1.1 Compilation

Hi;

I want to compile libpcap and I did following steps

1. ./configure --without-flex --without-bison
2. make

When I run make command I am getting following error messages
===============================================
./runlex.sh flex -oscanner.c scanner.l
yacc -d grammar.y
mv y.tab.c grammar.c
mv y.tab.h tokdefs.h

scanner.l:335: error: (Each undeclared identifier is reported only once

I downloaded libpcap from http://www.tcpdump.org/.

I installed flex in my machine and changed configure and runlex.sh scripts according to it.

Can anybody suggest me what I need to do to remove above errors.
I installed flex and

What's on (or before) these lines?
Perhaps your yacc grammar is bad?

>extern YYSTYPE yylval;

Hi,

You have available a binary depot ready to install in HP-UX:
http://hpux.connect.org.uk/hppd/hpux/Networking/Admin/libpcap-1.1.1/

Keep attention about package dependencies (bison, flex) also available in the site. Very important that you read the instalation doc:
http://hpux.connect.org.uk/hppd/cgi-bin/wwwtar?/hpux/Networking/Admin/libpcap-1.1.1/libpcap-1.1.1-src-11.11.tar.gz+libpcap-1.1.1/HPUX.Install+text

Rgds.
