|  | 2 | ----------------------------------------- | 
|  | 3 |  | 
|  | 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. | 
|  | 7 |  | 
|  | 8 | This will allow you to execute Mono-based .NET binaries just like any | 
|  | 9 | other program after you have done the following: | 
|  | 10 |  | 
|  | 11 | 1) You MUST FIRST install the Mono CLR support, either by downloading | 
|  | 12 | a binary package, a source tarball or by installing from CVS. Binary | 
|  | 13 | packages for several distributions can be found at: | 
|  | 14 |  | 
|  | 15 | http://go-mono.com/download.html | 
|  | 16 |  | 
|  | 17 | Instructions for compiling Mono can be found at: | 
|  | 18 |  | 
|  | 19 | http://www.go-mono.com/compiling.html | 
|  | 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 |  | 
|  | 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 | 
| Matt LaPlante | 84eb8d0 | 2006-10-03 22:53:09 +0200 | [diff] [blame] | 29 | cannot be easily supported with binfmt_misc. | 
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 30 | Read the file 'binfmt_misc.txt' in this directory to know | 
|  | 31 | more about the configuration process. | 
|  | 32 |  | 
| Adrian Bunk | 338cec3 | 2005-09-10 00:26:54 -0700 | [diff] [blame] | 33 | 3) Add the following entries to /etc/rc.local or similar script | 
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 34 | to be run at system startup: | 
|  | 35 |  | 
|  | 36 | # Insert BINFMT_MISC module into the kernel | 
|  | 37 | if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then | 
|  | 38 | /sbin/modprobe binfmt_misc | 
|  | 39 | # Some distributions, like Fedora Core, perform | 
|  | 40 | # the following command automatically when the | 
| Lucas De Marchi | 970e248 | 2012-03-30 13:37:16 -0700 | [diff] [blame] | 41 | # binfmt_misc module is loaded into the kernel | 
|  | 42 | # or during normal boot up (systemd-based systems). | 
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 43 | # Thus, it is possible that the following line | 
| Lucas De Marchi | 970e248 | 2012-03-30 13:37:16 -0700 | [diff] [blame] | 44 | # is not needed at all. | 
|  | 45 | mount -t binfmt_misc none /proc/sys/fs/binfmt_misc | 
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 46 | fi | 
|  | 47 |  | 
|  | 48 | # Register support for .NET CLR binaries | 
|  | 49 | if [ -e /proc/sys/fs/binfmt_misc/register ]; then | 
|  | 50 | # Replace /usr/bin/mono with the correct pathname to | 
|  | 51 | # the Mono CLR runtime (usually /usr/local/bin/mono | 
|  | 52 | # when compiling from sources or CVS). | 
|  | 53 | echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register | 
|  | 54 | else | 
|  | 55 | echo "No binfmt_misc support" | 
|  | 56 | exit 1 | 
|  | 57 | fi | 
|  | 58 |  | 
|  | 59 | 4) Check that .exe binaries can be ran without the need of a | 
|  | 60 | wrapper script, simply by launching the .exe file directly | 
|  | 61 | from a command prompt, for example: | 
|  | 62 |  | 
|  | 63 | /usr/bin/xsd.exe | 
|  | 64 |  | 
|  | 65 | NOTE: If this fails with a permission denied error, check | 
|  | 66 | that the .exe file has execute permissions. |
