To build the system (experts only): Requirements: - Your build environment must be FreeBSD 9.2-RELEASE (building on FreeBSD 10 or 11 is not supported at this time). - amd64 or i386 for i386 builds; an amd64 for amd64 builds. 8GB of memory, or an equal/greater amount of swap space, is also required - You will need the following ports/packages when compiling anything FreeNAS-related: - devel/git - sysutils/cdrtools - archivers/pxz - lang/python (2.7 or later) (and all the dependencies that these ports/pkgs install, of course) Building the System Quickstart Flow: - Checking out the code from git: % cd /path/to/your-build-filesystem % git clone git://github.com/freenas/freenas.git % cd freenas - Build it % make git-external % make release This will also fetch TrueOS and ports for the build from github. The End Result: If your build completes successfully, you'll have both 32 and 64 bit release products in the release_stage directory. You will also have a tarball in your build directory containing the entire release for easy transport.
