Cannot install tcpreplay 3.4.4

Question

I'm trying to install Tcpreplay 3.4.4 on my server that is running RHEL 5.6 and has libpcap1.1.1 installed. When I ran "./configure", it stopped at

checking for libpcap... /usr/local
checking for library containing pcap_close... no
configure: error: Unable to link libpcap in /usr/local

How to I resolve this?

Thank you!

Answer 1

Install libnl-devel.

There is a hard coded requirement for libnl in the configure file that throws:

checking for libpcap... /usr/local
checking for library containing pcap_close... no
configure: error: Unable to link libpcap in /usr/local

Or in my case:

checking for libpcap... /usr
checking for library containing pcap_close... no
configure: error: Unable to link libpcap in /usr

Had this issue myself, not on RHEL but on a white box derivative of it, but just worked out a way around it: The problem was an earlier version of libpcap bundled with tcpdump.

Do:

tcpdump -h

And you might see something like:

tcpdump version 3.xxx
libpcap version 0.9.xxx

Which would prove whether that is your issue or not.

I guess you downloaded and compiled libpcap1.1.1, so take that back out first:

cd libpcap-1.1.1
make uninstall

Next take out your existing tcpdump using whatever your package tool is, eg.:

yum remove tcpdump
rpm -e tcpdump

Now put your new libpcap back

cd libpcap-1.1.1
./configure
make
make install

You probably want to get a new tcpdump, so download and untar tcpdump-4.1.1.tar.gz and compile it...

tar -zxvf tcpdump-4.1.1.tar.gz
cd tcpdump-4.1.1
./configure
make
make install

Hope that fixes it for you!

And finally, go ahead and compile your new tcpreplay:

cd tcpreplay 3.4.4
./configure
make
make install

Hope that does the trick for you!

This worked for me

./configure LDFLAGS=-ldag 

I have a DAG card installed in my server, and some of the test scripts that tcpreplay's configure script was trying to compile were failing on dag_*() methods.
