Prerequisites

In order to compile PcapPlusPlus on Linux please make sure you have the following components installed:

  1. Xcode which contains all prerequisites required for PcapPlusPlus including gcc/g++ compiler and libpcap with all relevant header files
  2. Make sure you have Xcode Command Line Tools. You can install it by running the following command in Terminal:

  3. PcapPlusPlus is available for both Intel and Apple silicon (M1) processors. To build for Apple silicon please use the --arm64 flag (please see below)
  4. OPTIONAL - install Zstd if you wish to enable PCAPNG streaming compression support:

Configuration

Run the configuration script from PcapPlusPlus main directory:

This script has the following command-line switches (you can also view then by running ./configure-mac_os_x.sh --help or ./configure-mac_os_x.sh -h):

Piplets Mac Os 11

no switchesuse the default configuration
--use-immediate-modeuse libpcap immediate mode which enables getting packets as fast as possible (supported on libpcap>=1.5)
--set-direction-enabledset direction for capturing incoming or outgoing packets (supported on libpcap>=0.9.1)
--install-dirset a custom installation directory. Default is /usr/local
--libpcap-include-dirlibpcap header files directory. This parameter is optional and if omitted PcapPlusPlus will look for the header files in the default include paths
--libpcap-lib-dirlibpcap pre compiled lib directory. This parameter is optional and if omitted PcapPlusPlus will look for the lib file in the default lib paths
--use-zstduse Zstd for PCAPNG streaming compression. This parameter is optional
--arm64build for Apple Silicon M1 (arm64 architecture). This flag can be used for cross-compilation which means you can don’t have to run the build on an Apple silicon M1 machine
-h, --helpdisplays a help message and exits. No further actions are performed

Here are a few examples:

Default configuration:

Configure PcapPlusPlus with libpcap’s immediate mode:

Configure PcapPlusPlus with libpcap’s set direction:

Provide non-standard paths for libpcap header and library files:

Download

Provide a custom installation directory:

Use Zstd for pcapng compression:

Build the code

After running the config script, you’re can safely build the code:

  1. Run make or make all from PcapPlusPlus main directory
  2. This should compile all libraries, unit-tests and examples
  3. To build the libraries only (without the unit-tests and examples) run make libs instead of make all
  4. After compilation you can find the libraries, examples, header files and helpful makefiles under the Dist directory

Installation

After build is complete you can run the installation script which will copy the library and header files to the installation directory:

The default installation directory is /usr/local which means the header files will be copied to /usr/local/include/pcapplusplus and the library files will be copied to /usr/local/lib.

You can change the installation directory by using the --install-dir switch in the configuration script.

Running tests

PcapPlusPlus contains a set of test-cases you can run to make sure that everything works correctly on your system. This guide contains detailed instructions on how to run them.

I should note that the last example really needs 3 sessions.

2 running tail -f pipe
and another running cat > pipe
try it a couple times starting and stoping each tail session
sorry for the mistake

i am jack's amusing sig file

Named pipes are still pipes and not regular files. For example trying to seek to a particular offset in a named pipe will fail. For that reason, sometimes you can get away with named pipes, and sometimes you can't.

Last time I checked (haven't got time now), named pipes aren't honoured in the GUI. A couple of years back I had a named pipe that had a perl script on the end waiting for someone to read it. No GUI apps could open it. :-(
I went to the trouble of sending Apple feedback about it. Anyone know if this has changed?

UNIX uses named pipes to implement sockets, so sometimes named pipes will show up as FTP servers in the Finder. Other times, I've seen them show up as ordinary files that would completely freeze the Finder if you looked at them funny. For example, by right-clicking on a named pipe, and going to the 'Open With' submenu.

For whatever reason, the shorten command line program doesn't accept '-' as a valid output file (stdout). This prevents you from piping its output into LAME, and getting a direct conversion from SHN to MP3. To get around the problem, I've been using named pipes. Here's my shn2mp3 script: It's worked fine for me, but if anyone out there knows a better, cleaner, safer way to do this, I'd love to hear it.
DownloadNice hint - could be really useful, but I can't seem to get shorten to work. Here's the response in my Terminal:

I installed shorten using 'fink install shorten'. Where did you get your from? Any idea what magic number might be about? Despite the error response, 'shorten -h' doesn't give any info about magic numbers.

Oh, not surprisingly, the resulting MP3 file is a wash of static. :-(

My mistake! I used the commands above for SHD->MP3 conversion, when I meant to use the RM->MP3 conversion. Shorten was complaining because I wasn't feeding it an SHD file! Now, if I can just compile mplayer with the realaudio codecs, I'll have this working....

I've spent way too much time in the last 2 days trying to get mplayer to compile for Mac OS X, encouraged by the original example in this thread of being able to convert RealAudio to MP3. (Actually, the version available in Fink compiles fine, but does not support Real codecs. The latest source files fail out of the box with a compilation error since they tries to use a '-rdynamic' option with GCC. Removing that option by hacking the config files gets past compiling, but just causes mplayer to crash later when trying to load Real files.)
I sent a private email to the original hint author (fracai), and he admitted that he based his hint on something he does in Linux.
So, the named pipes is a legitimate concept, but the mplayer conversion of RealAudio files is a bit of a 'tease'. If anyone else can get mplayer to properly read Real files, I'd love to know!

I am trying to convert a non DRM WMA file to mp3 using this method.
i follow theinstructions, substituting where appropriate, and here is what (doesn't) happen.
i make the named pipe
fine no problem
i start lame, so far no problems
i have to go to another terminal window to start mplayer.
as soon as i start mplayer, the mplayer window says broken pipe immediately after outputting 'Starting Playback'
the other terminal window (the one lame was started in)
outputs a bunch of info, and then
Writing LAME tag ... Done.
and quits
Where does the fault lie?
i have never used lame before
and i don't normally use mplayer from the command line
Any ideas?

To make your example work, I had to use `cat pipe` in the second terminal instead of `tail -f pipe`
