OCCAM currently works fine on Linux, OS X, and FreeBSD. You will need an installation of llvm-3.5. If you need to generate application bitcode, you will want to install WLLVM.

Set where OCCAM's library will be stored:

  export OCCAM_HOME={path to location in your home directory}

Point to your LLVM's location, if non-standard:

  export LLVM_HOME=/usr/local/llvm-3.5
  export LLVM_CONFIG=llvm-config-3.5

Set where system libraries, including Google Protocol Buffers, are located:

  export LD_FLAGS='-L/usr/local/lib'

Build and install OCCAM with:

  make
  make install

You can choose to record logs from the OCCAM tool by setting the following variables:

  export OCCAM_LOGFILE={absolute path to log location}
  export OCCAM_LOGLEVEL={INFO, WARNING, or ERROR}
