addhe@google:~/barnyard$ autoreconf -fvi

autoreconf: /usr/bin/autoconf failed with exit status: 1

how to fix this ? just simply using this command


#sudo apt-get install libtool


if you’re install IDC snort like me just make sure this package already installed, it this below package already installed then you will not face error above.


#apt-get -y install libwww-perl libnet1 libnet1-dev libpcre3 libpcre3-dev autoconf libcrypt-ssleay-perl libtool libssl-dev build-essential automake gcc make flex bison
