Build Instructions
==================
Install dependencies
--------------------
::
sudo apt-get install -y git cmake autoconf pkg_config libtool
Libmemif is now part of VPP repository. Follow fd.io wiki to pull source
code from VPP repository.
https://wiki.fd.io/view/VPP/Pulling,_Building,_Running,_Hacking_and_Pushing_VPP_Code#Pushing_Patches
Libmemif is located under extras/libmemif. From the vpp workspace root directory::
mkdir -p extras/libmemif/build
cd extras/libmemif/build
cmake ..
make install
Verify installation:
--------------------
::
./examples/icmp_responder -?
Use ``-?`` flag to display help::
LIBMEMIF EXAMPLE APP: icmp_responder_example
==============================
libmemif version: 4.0, memif version: 2.0
==============================
In this example, memif endpoint connects to an external application.
The example application can resolve ARP and reply to ICMPv4 packets.
The program will exit once the interface is disconnected.
==============================
Usage: icmp_responder [OPTIONS]

Running tests:
--------------
Tests needs to their proper functioning Unity framework which is depended externally and cloned from official git repository::
mkdir -p extras/libmemif/build
cd extras/libmemif/build
cmake ..
make
ctest
``ctest`` will execute the tests and print out brief information about test suites with their statuses.
In case we want verbose: ::
ctest --verbose
ctest --extra-verbose
If there are any needs to debug tests, just add to cmake command ``-DCMAKE_BUILD_TYPE=Debug`` flag.
