About this task
Before you begin
The following are required in order to build and install libpcap:
- GCC version 4.0 or later
- GNU make
- flex and bison or lex and yacc. Some versions of lex are insufficient to compile libpcap; if this is the case, install flex and bison.
To install libpcap with Napatech extensions:
- Download the product package for your operating system from supportportal.napatech.com (the Napatech Support Portal).
Expand the product package archive and enter the ntanl_package_3gd-x.y.z-linux/pcap directory:
$ tar xzf ntanl_package_3gd-x.y.z-linux.tar.gz $ cd ntanl_package_3gd-x.y.z-linux $ cd pcap
Enter the nt_libpcap_x.y.z directory:
$ tar xfz nt_libpcap_x.y.z.tar.gz $ cd nt_libpcap_x.y.z
Determine which version of libpcap with Napatech extensions that you want to install. Refer to the README file for more information about available versions.
$ less README $ cd libpcap-x.y.z
Configure for installation in the Napatech driver installation directory:
$ ./configure --prefix=/opt/napatech3
To install the libpcap static and shared library, execute the following command:
$ sudo gmake installFor Linux:
$ sudo make install
