Finding libpcap when using CMake

0

Hi,

I'm compiling from source on ARM based ubuntu (14.04) system similar to Raspberry Pi. I've hit the: tshark: This version of TShark was not built with support for capturing packets message and I've read that I must "use --with-pcap option in your configure."

I see the following files at the top level:

$ ls -1 *conf*
INSTALL.configure
cmakeconfig.h.in
config.guess
config.h
config.h.win32
config.nmake
config.sub
configure.ac

Where should I enable the use of pcap? Please be as specific as possible. Do I need to apt-get any other library for pcap?

I'm compiling by: cmake . && make

Where did you read the statement that you must "use --with-pcap option in your configure."? That statement needs to be updated to handle CMake as well as autoconf; --with-pcap is an autoconf option, and doesn't apply if you're using CMake.

Are you compiling on the ARM-based system to build a program to run on the same system, or are you compiling on some other system to produce a program to run on the ARM-based system, i.e. are you cross-compiling?

Hi, I'm doing a native compilation on the ARM based system that I intend to run. My installed compiler is gcc 4.8.x. I'll get back to you on where the message to use cap came from.

You should get the libpcap development package libpcap0.8-dev. That provides you with the development files you need to compile using --with-pcap (which cmake should be able to find just fine actually).

At least if this is doing a native compile. The package might have some other name if they're cross-compiling.

Both CMake and autotools should find libpcap without any help if the development package is installed; no need for --with-pcap= with autotools or -DCMAKE_PREFIX_PATH= with CMake.
