0001 Mono(tm) Binary Kernel Support for Linux
0002 -----------------------------------------
0003
0004 To configure Linux to automatically execute Mono-based .NET binaries
0005 (in the form of .exe files) without the need to use the mono CLR
0006 wrapper, you can use the BINFMT_MISC kernel support.
0007
0008 This will allow you to execute Mono-based .NET binaries just like any
0009 other program after you have done the following:
0010
0011 1) You MUST FIRST install the Mono CLR support, either by downloading
0012 a binary package, a source tarball or by installing from Git. Binary
0013 packages for several distributions can be found at:
0014
0015 https://www.mono-project.com/download/
0016
0017 Instructions for compiling Mono can be found at:
0018
0019 https://www.mono-project.com/docs/compiling-mono/linux/
0020
0021 Once the Mono CLR support has been installed, just check that
0022 ``/usr/bin/mono`` (which could be located elsewhere, for example
0023 ``/usr/local/bin/mono``) is working.
0024
0025 2) You have to compile BINFMT_MISC either as a module or into
0026 the kernel (``CONFIG_BINFMT_MISC``) and set it up properly.
0027 If you choose to compile it as a module, you will have
0028 to insert it manually with modprobe/insmod, as kmod
0029 cannot be easily supported with binfmt_misc.
0030 Read the file ``binfmt_misc.txt`` in this directory to know
0031 more about the configuration process.
0032
0033 3) Add the following entries to ``/etc/rc.local`` or similar script
0034 to be run at system startup:
0035
0036 .. code-block:: sh
0037
0038 # Insert BINFMT_MISC module into the kernel
0039 if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then
0040 /sbin/modprobe binfmt_misc
0041 # Some distributions, like Fedora Core, perform
0042 # the following command automatically when the
0043 # binfmt_misc module is loaded into the kernel
0044 # or during normal boot up (systemd-based systems).
0045 # Thus, it is possible that the following line
0046 # is not needed at all.
0047 mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
0048 fi
0049
0050 # Register support for .NET CLR binaries
0051 if [ -e /proc/sys/fs/binfmt_misc/register ]; then
0052 # Replace /usr/bin/mono with the correct pathname to
0053 # the Mono CLR runtime (usually /usr/local/bin/mono
0054 # when compiling from sources or CVS).
0055 echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register
0056 else
0057 echo "No binfmt_misc support"
0058 exit 1
0059 fi
0060
0061 4) Check that ``.exe`` binaries can be ran without the need of a
0062 wrapper script, simply by launching the ``.exe`` file directly
0063 from a command prompt, for example::
0064
0065 /usr/bin/xsd.exe
0066
0067 .. note::
0068
0069 If this fails with a permission denied error, check
0070 that the ``.exe`` file has execute permissions.
