Question

I am trying to install nprobe on my system when i followed the following steps

sudo apt-get install libpcap-dev
cd nprobe/plugsins
./buildMakefile.sh  >Makefile.in
cd ..
./autogen.sh 
./configure
  make

all above commands run absolutely fine but when i try to run make its give me the following error.
usr/lib/libpcap.so: undefined reference to `pcap_lex' collect2: ld returned 1 exit status

Answer 1

Yeah... we came across this with our netflow exporter. You need to have flex installed (the GNU implementation of UNIX lex). You'll probably also need to install bison, and I think it might use m4 too.

Answer 2

It seems that not only libpcap-devel need to be installed, but also libpcap.
