      1Mono(tm) Binary Kernel Support for Linux
      2-----------------------------------------
      3
      4To configure Linux to automatically execute Mono-based .NET binaries
      5(in the form of .exe files) without the need to use the mono CLR
      6wrapper, you can use the BINFMT_MISC kernel support.
      7
      8This will allow you to execute Mono-based .NET binaries just like any
      9other program after you have done the following:
     10
     111) You MUST FIRST install the Mono CLR support, either by downloading
     12   a binary package, a source tarball or by installing from Git. Binary
     13   packages for several distributions can be found at:
     14
     15	https://www.mono-project.com/download/
     16
     17   Instructions for compiling Mono can be found at:
     18
     19	https://www.mono-project.com/docs/compiling-mono/linux/
     20
     21   Once the Mono CLR support has been installed, just check that
     22   ``/usr/bin/mono`` (which could be located elsewhere, for example
     23   ``/usr/local/bin/mono``) is working.
     24
     252) You have to compile BINFMT_MISC either as a module or into
     26   the kernel (``CONFIG_BINFMT_MISC``) and set it up properly.
     27   If you choose to compile it as a module, you will have
     28   to insert it manually with modprobe/insmod, as kmod
     29   cannot be easily supported with binfmt_misc.
     30   Read the file ``binfmt_misc.txt`` in this directory to know
     31   more about the configuration process.
     32
     333) Add the following entries to ``/etc/rc.local`` or similar script
     34   to be run at system startup:
     35
     36   .. code-block:: sh
     37
     38    # Insert BINFMT_MISC module into the kernel
     39    if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then
     40        /sbin/modprobe binfmt_misc
     41	# Some distributions, like Fedora Core, perform
     42	# the following command automatically when the
     43	# binfmt_misc module is loaded into the kernel
     44	# or during normal boot up (systemd-based systems).
     45	# Thus, it is possible that the following line
     46	# is not needed at all.
     47	mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
     48    fi
     49
     50    # Register support for .NET CLR binaries
     51    if [ -e /proc/sys/fs/binfmt_misc/register ]; then
     52	# Replace /usr/bin/mono with the correct pathname to
     53	# the Mono CLR runtime (usually /usr/local/bin/mono
     54	# when compiling from sources or CVS).
     55        echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register
     56    else
     57        echo "No binfmt_misc support"
     58        exit 1
     59    fi
     60
     614) Check that ``.exe`` binaries can be ran without the need of a
     62   wrapper script, simply by launching the ``.exe`` file directly
     63   from a command prompt, for example::
     64
     65	/usr/bin/xsd.exe
     66
     67   .. note::
     68
     69      If this fails with a permission denied error, check
     70      that the ``.exe`` file has execute permissions.
