    Problem Ntop installation


    Hello all,
    I hope you guys/gals can help me with this problem.
    I'm trying to install ntop on a linux system and I got the next errors:

    /root/downloads/ntop-3.3.8/.libs/libntop.so: undefined reference to `pcap_lex'
    collect2: ld returned 1 exit status
    make[2]: *** [ntop] Error 1
    make[1]: *** [all-recursive] Error 1
    make: *** [all] Error 2

    This when I use the "make" command.
    I'm running centOS 5.2.

    You can get ntop packages for CentOS from here.

    I installed the RPM and it runned. just try to do that. Otherwise try to check Yum (it can be another program with your Linux) and see if it is listed there. If its listed there it should work.
    Good luck

    I try the rpm earlier with no succes. It says rrdtools was missing. but it was already installed. doh!

    In a desesparate cause, I downgrade lpcap from 1.0.0 to 0.9.3 and it fix my issue! I was able to run make and make install without any errors and ntop is running fine now.
    CentOS 5.2 with ntop 3.3.8 to.

    Thank you for your help.
