Binary + packages for several distributions can be found at: + + https://www.mono-project.com/download/ + + Instructions for compiling Mono can be found at: + + https://www.mono-project.com/docs/compiling-mono/linux/ + + Once the Mono CLR support has been installed, just check that + ``/usr/bin/mono`` (which could be located elsewhere, for example + ``/usr/local/bin/mono``) is working. + +2) You have to compile BINFMT_MISC either as a module or into + the kernel (``CONFIG_BINFMT_MISC``) and set it up properly. + If you choose to compile it as a module, you will have + to insert it manually with modprobe/insmod, as kmod + cannot be easily supported with binfmt_misc. + Read the file ``binfmt_misc.txt`` in this directory to know + more about the configuration process. + +3) Add the following entries to ``/etc/rc.local`` or similar script + to be run at system startup: + + .. code-block:: sh + + # Insert BINFMT_MISC module into the kernel + if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then + /sbin/modprobe binfmt_misc + # Some distributions, like Fedora Core, perform + # the following command automatically when the + # binfmt_misc module is loaded into the kernel + # or during normal boot up (systemd-based systems). + # Thus, it is possible that the following line + # is not needed at all. + mount -t binfmt_misc none /proc/sys/fs/binfmt_misc + fi + + # Register support for .NET CLR binaries + if [ -e /proc/sys/fs/binfmt_misc/register ]; then + # Replace /usr/bin/mono with the correct pathname to + # the Mono CLR runtime (usually /usr/local/bin/mono + # when compiling from sources or CVS). + echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register + else + echo "No binfmt_misc support" + exit 1 + fi + +4) Check that ``.exe`` binaries can be ran without the need of a + wrapper script, simply by launching the ``.exe`` file directly + from a command prompt, for example:: + + /usr/bin/xsd.exe + + .. note:: + + If this fails with a permission denied error, check + that the ``.exe`` file has execute permissions. |
