170 LP64 ABI (x86-64 in x86 systems), where pointers and longs are 64 bits.
243 You can do this with the ``--rt`` and ``--no-rt`` options from the command line.
259 This can be controlled with the ``--rt-ratio=<ratio>`` and ``-rt-drift=<drift>``
262 ``ratio - 1``.
266 In this way if, for example, ``--rt-ratio=2`` is given, the simulated time
268 Similarly if ``--rt-drift=-100e-6`` is given, the simulated time will progress
270 Note that these 2 options have no meaning when running in non real-time

359 An entropy device based on the host :c:func:`random` API.
360 This device will generate the same sequence of random numbers if initialized
361 with the same random seed.
362 You can change this random seed value by using the command line option:
363 :samp:`--seed={<random_seed>}` where the value specified is a 32-bit integer

431 You may also need to set ``pkg-config`` to correctly pickup the SDL2 install path.
433 On Ubuntu the package is ``libsdl2-dev`` whose 64bit version is likely installed by default.
434 On an Ubuntu 18.04 host system, you can install the ``pkg-config`` and the 32bit
435 ``libsdl2-dev:i386`` packages, and configure the pkg-config search path with these commands:
437 .. code-block:: console
439 $ sudo dpkg --add-architecture i386
