Build Documentation 64bit

Advanced users can create 64-bit instead of 32-bit builds.

  • Don't get confused by the term amd64. It runs on both, Intel and AMD. amd64 is only how Debian names the kernel. It works equally well on Intel and AMD.
  • Whonix 13: By default, 32-bit Linux is used. [1] 64-bit builds are less tested due to a lack of developer manpower, but should work well in principle.

To build Whonix 13 64-bit, add the following build parameter. [2] [3]

--arch amd64

To build Whonix 14 32-bit, add the following build parameter.

--arch i386
  • kFreeBSD is entirely untested and most likely needs additional work (see footnotes). [4]
  • Whonix for arm64 development discussion:

  • Generally speaking, 64-bit builds cannot be created if running a 32 bit host kernel. [5] In this case, try installing the packages linux-image-amd64 and linux-headers-amd64 on your host, then boot the amd64 kernel by choosing it in the boot menu. The whole system does not require re-installation; just be sure to boot with an amd64 kernel. Alternatively, consider to re-install your host using amd64.


  1. The linux-image-686-pae linux-headers-686-pae linux-image-486 linux-headers-486 kernel is installed, and only for compatibility reasons. Users with modern hardware can omit linux-image-486 linux-headers-486 and those with ancient hardware can omit linux-image-686-pae linux-headers-686-pae.
  2. This only installs the linux-image-amd64 linux-headers-amd64 kernel.
  3. For --arch amd64, the following is implicitly added (unless settings are manually changed).
    --kernel linux-image-amd64 --headers linux-headers-amd64
  4. kFreeBSD (32-bit).
    --arch kfreebsd-i386 --kernel kfreebsd-image --headers kfreebsd-headers

    kFreeBSD (64-bit).

    --arch kfreebsd-amd64 --kernel kfreebsd-image --headers kfreebsd-headers
