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 http://www.mono-project.com/download/ 16 17 Instructions for compiling Mono can be found at: 18 19 http://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. 71
