Operating Systems

SF-TAP flow abstractor is available on the following OSes.

How to Compile

Environment Variables

Before compiling, set environment variables for cmake as follows.

$ export CMAKE_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
$ export CMAKE_INCLUDE_PATH=/usr/include:/usr/local/include

Compile

$ cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt
$ make

If you want to compile as debug mode, set an option of CMAKE_BUILD_YPE=Debug when running cmake. Debug mode passes an option of -g and a definition of DEBUG=1 to the compiler.

$ cmake -DCMAKE_BUILD_TYPE=Debug CMakeLists.txt
$ make

If you want to build static library, set an option of COMPILE_STATIC_LIB=1.

$ cmake -DCOMPILE_STATIC_LIB=1 CMakeLists.txt
$ make

If you want to use jemalloc, set an option of USE_JEMALLOC=1.

$ cmake -DUSE_JEMALLOC=1 CMakeLists.txt
$ make

If you want to use netmap, set an option of USE_NETMAP=1.

$ cmake -DUSE_NETMAP=1 CMakeLists.txt
$ make

You can use a verbose mode when compiling.

$ make VERBOSE=1

Tell Root Directories for Libraries

If you installed above libraries in unordinal places (not /usr or /usr/local), please tell paths to the directoris as follows.

$ cmake -DBOOST_ROOT=/homebrew -DEVENT_ROOT=/homebrew -DRE2_ROOT=/homebrew -DYAMLCPP_ROOT=/homebrew .

How to run SF-TAP flow abstractor

You can specify a network interface by -i option, and a config file by -c option.

Example:

$ ./src/sftap_fabs -i eth0 -c ./examples/fabs.yaml

If you encounter an error as follows,

terminate called after throwing an instance of 'std::runtime_error'
what():  locale::facet::_S_create_c_locale name not valid

please install the suitable language package like as follows.

$ apt-get install language-pack-ja

Use netmap

If you want to use netmap, pass -n option as follows.

$ ./src/sftap_fabs -i eth0 -c ./examples/fabs.yaml -n
