Building on FreeBSD

While cross-compilation of FreeBSD binaries is not available yet, it is possible to build binaries in a native FreeBSD environment. In order to do so you will firstly need to install some packages:

$ sudo pkg install git gmake pkgconf go-bindata

Then you will need to install Yara, which is normally available in ports:

$ cd /usr/ports/security/yara

Before installing it, it is recommended that you modify the file Makefile to add --without-crypto to CONFIGURE_ARGS (if you don't need the Yara modules enabled in the Makefile, feel free to remove them). Now you can proceed with installing:

$ sudo make && sudo make install

Now you can move to the directory that contains the Kraken source code and build it with:

$ BACKEND=example.com RULES=test/ gmake freebsd
