Build Instructions

FBOSS is being tested on Ubuntu 16.04.

Required packages

  • cmake3.0.2 or higher
  • gcc/g++ 4.9+ (with c++14 support)

The provided getdeps.sh script will fetch the dependencies required. If they are available as Ubuntu packages, then they will be installed through apt-get. If they are not, then they will be downloaded to external/ and built from source.

If you want to build them manually, the dependencies are as follows:

  • folly, built from source and installed
  • folly's own prerequisites: double-conversion, gflags, and glog
  • fbthrift, built from source and installed
  • iproute2-3.19.0: download from here
  • Broadcom's OpenNSL

Once the prerequisites are available, take the following steps.

Clone the repository:

git clone https://github.com/facebook/fboss.git

If you installed dependencies manually, CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH must be modified to include the paths to the dependencies. If you use getdeps.sh, then this should work out of the box.

Build as follows:

mkdir fboss/build                         # start with a clean build dir
cd fboss/build
cmake ..                                  # build the Makefile
NPROC=$(grep -c processor /proc/cpuinfo)  # lookup cores in system
make "-j$NPROC"                           # spawn a thread per core

FYI: the build status of open source fboss is tracked at: https://travis-ci.org/facebook/fboss

The produced executables are sim_agent and wedge_agent in the build directory.
