1 Mono(tm) Binary Kernel Support for Linux
2 -----------------------------------------
4 To configure Linux to automatically execute Mono-based .NET binaries
5 (in the form of .exe files) without the need to use the mono CLR
6 wrapper, you can use the BINFMT_MISC kernel support.
8 This will allow you to execute Mono-based .NET binaries just like any
9 other program after you have done the following:
11 1) 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:
15 http://www.mono-project.com/download/
17 Instructions for compiling Mono can be found at:
19 http://www.mono-project.com/docs/compiling-mono/linux/
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.
25 2) 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.
33 3) Add the following entries to ``/etc/rc.local`` or similar script
34 to be run at system startup:
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
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
57 echo "No binfmt_misc support"
61 4) 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::
69 If this fails with a permission denied error, check
70 that the ``.exe`` file has execute permissions.
