.TH Mono "mkbundle"
.SH NAME
mkbundle, mkbundle2 \- Creates a bundled executable.
.SH SYNOPSIS
.PP
.B mkbundle [options] assembly1 [assembly2 ...]
.SH DESCRIPTION
\fImkbundle\fP generates an executable program that will contain
static copies of the assemblies listed on the command line.  By
default only the assemblies specified in the command line will be
included in the bundle.  To automatically include all of the
dependencies referenced, use the "--deps" command line option.
.PP
There are two modes of operation, one uses an existing Mono binary or
a server-hosted list of binaries and is enabled when you use either
the 
.B --cross,
.B --sdk
or the
.B --runtime
command line options.   
.PP
An older mechanism creates a small C stub that links against the
libmono library to produce a self-contained executable and requires a
C compiler.   It is described in the "OLD EMBEDDING" section below.
.PP
For example, to create a bundle for hello world, use the following
command:
.nf

        $ mkbundle -o hello --simple hello.exe

.fi
.PP
You can configure options to be passed to the Mono runtime directly
into your executable, for this, use the 
.I --options
flag.  For example, the following disables inlining, by passing the
"-O=-inline" command line option to the embedded executable:
.nf

        $ mkbundle -o hello --options -O=-inline --simple hello.exe

.PP
The simple version allows for cross-compiling, this requires a Mono
runtime to be installed in the ~/.mono/targets/TARGET/mono to be
available.   You can use the "--local-targets" to list all available
targets, and the "--cross" argument to specify the target, like this:
.nf

        $ mkbundle --local-targets      
        Available targets:
                default - Current System Mono
                4.4.0-macosx-x86
                4.4.0-debian-8-arm64
        $ mkbundle --cross 4.4.0-debian-8-powerpc hello.exe -o hello-debian

.fi
.PP
The above will bundle your native library into hello-debian for
a Debian 8 system running on a PowerPC machine.
.PP
We provide pre-packages binaries for Mono for various architectures,
which allow you to cross compile, use the
.B --list-targets
to get a list of all targets supported, and use the 
.B --fetch-target
flag to retrieve a target that you do not have installed, like this:
.nf
        
        $ mkbundle --list-targets
        Cross-compilation targets available:
        4.4.0-linux-libc2.13-amd64
        4.4.0-linux-libc2.13-armel
        4.4.0-linux-libc2.13-armhf
        4.4.0-linux-libc2.13-i386
        4.4.0-macos-10.7-amd64
        4.4.0-macos-10.7-i386
        4.4.2-linux-libc2.13-amd64
        4.4.2-linux-libc2.13-armel
        4.4.2-linux-libc2.13-armhf
        4.4.2-linux-libc2.13-i386
        4.4.2-macos-10.7-amd64
        4.4.2-macos-10.7-i386

        $ mkbundle --fetch-target 4.4.2-macos-10.7-i386

.fi
.PP
And then you can produce a binary that will run on 32-bit Mono on
MacOS:
.nf

        $ mkbundle --cross 4.4.2-macos-10.7-i386 hello.exe -o hello-macos

.fi
.PP
Downloaded targets are stored
.B ~/.mono/targets
directory.
.SH OPTIONS
.TP 
.I "--config FILE"
Specifies that a machine.config file must be bundled as well.
Typically this is $prefix/etc/mono/1.0/machine.config or
$prefix/etc/mono/2.0/machine.config depending on the profile that you
are using (1.0 or 2.0)
.TP
.I "--config-dir DIR"
When passed, DIR will be set for the MONO_CFG_DIR environment variable
.TP
.I "--cross target"
Use this to request mkbundle generate a cross-compiled binary.  It
Creates a bundle for the specified target platform.  The target must
be a directory in ~/.mono/targets/ that contains an SDK installation
as produced by the mono-package-runtime tool.  You can get a list of
the precompiled versions of the runtime using --list-targets and you
can fetch a specific target using the --fetch-target command line
option.
.Sp
This flag is mutually exclusive with 
.I --sdk
which is used to specify an absolute path to resolve the Mono runtime
from and the --runtime option which is used to manually construct the
cross-platform package.
.TP
.I "--deps"
This option will bundle all of the referenced assemblies for the
assemblies listed on the command line option.  This is useful to
distribute a self-contained image.
.TP
.I "--env KEY=VALUE"
Use this to hardcode an environment variable at runtime for KEY to be
mapped to VALUE.   This is useful in scenarios where you want to
enable certain Mono runtime configuration options that are controlled
by environment variables.
.TP
.I "--fetch-target target"
Downloads a precompiled runtime for the specified target from the Mono
distribution site.
.TP
.I "--i18n encoding"
Specified which encoding tables to ship with the executable.   By
default, Mono ships the supporting I18N.dll assembly and the
I18N.West.dll assembly.   If your application will use the
System.Text.Encoding.GetEncoding with encodings other than the West
encodings, you should specify them here.
.Sp
You can use the
.B none
parameter to request that no implicit encodings should be bundled,
including the supporting I18N.dll, use this option if you have ran a
linker on your own.
.Sp
You can use the 
.B all
flag to bundle all available encodings.
.Sp
Or you can use a comma delimited list of the workds CJK, MidWest,
Other, Rare and West to specificy which encoding assemblies to distribute.
.TP
.I "-L path"
Adds the `path' do the search list for assemblies.  The rules are the
same as for the compiler -lib: or -L flags.
.TP
.I "--library [LIB,]PATH"
Embeds the dynamic library file pointed to by `PATH' and optionally
give it the name `LIB' into the bundled executable.   This is used to
ship native library dependencies that are unpacked at startup and
loaded from the runtime. Multiple libraries should be specified in
dependency order, where later ones on the command line depend on
earlier ones.
.TP
.I "--lists-targets"
Lists all of the available local cross compilation targets available
as precompiled binaries on the Mono distribution server.
.TP
.I "--local-targets"
Lists all of the available local cross compilation targets.
.TP
.I "--cil-strip PATH"
Provides a CIL stripper that mkbundle will use if able to.
The intended use is to help reduce file size on AOT.
.TP
.I "--in-tree path/to/mono/source/root"
Provides mkbundle with a mono source repository from which to pull the necessary headers for compilation.
This allows mkbundle to run out of the project's source tree, useful for working with multiple runtimes and for
testing without installing.
.TP
.I "--managed-linker PATH"
Provides mkbundle access to a managed linker to preprocess the assemblies.
.TP
.I "--machine-config FILE"
Uses the given FILE as the machine.config file for the generated
application.   
.TP
.I  "--nodeps"
This is the default: \fImkbundle\fP will only include the assemblies that
were specified on the command line to reduce the size of the resulting
image created.
.TP
.I "-o filename"
Places the output on `out'.  If the flag -c is specified, this is the
C host program.  If not, this contains the resulting executable.
.TP
.I "--options OPTS"
Since the resulting executable will be treated as a standalone
program, you can use this option to pass configuration options to the
Mono runtime and bake those into the resulting executable.  These
options are specified as 
.I OPTS.
.Sp
You can use the above to configure options that you would typically
pass on the command line to Mono, before the main program is
executed.   
.Sp
Additionally, users of your binary can still configure their own
options by setting the 
.I MONO_ENV_OPTIONS
environment variable.
.TP
.I "--sdk SDK_PATH"
Use this flag to specify a path from which mkbundle will resolve the
Mono SDK from.   The SDK path should be the prefix path that you used
to configure a Mono installation.   And would typically contain files
lik
.I SDK_PATH/bin/mono
,
.I SDK_PATH/lib/mono/4.5
and so on.
.Sp
When this flag is specified,
.I mkbundle
will resolve the runtime, the framework libraries, unmanaged resources
and configuration files from the files located in this directory.
.Sp
This flag is mutually exlusive with 
.I --cross
.
.TP
.I "--target-server SERVER"
By default the mkbundle tool will download from a Mono server the
target runtimes, you can specify a different server to provide
cross-compiled runtimes.
.SH OLD EMBEDDING
.PP
The old embedding system compiles a small C stub that embeds the
C code and compiles the resulting executable using the system
compiler.   This requires both a working C compiler installation and
only works to bundle binaries for the current host.
.PP
The feature is still available, but we recommend the simpler, faster
and more convenient new mode.
.PP
For example, to create a bundle for hello world, use the following
command:
.nf

        $ mkbundle -o hello hello.exe
.fi
.PP
The above will pull hello.exe into a native program called "hello".  Notice
that the produced image still contains the CIL image and no
precompilation is done.
.PP
In addition, it is possible to control whether \fImkbundle\fP should compile
the resulting executable or not with the -c option.  This is useful if
you want to link additional libraries or control the generated output
in more detail. For example, this could be used to link some libraries
statically:
.nf

        $ mkbundle -c -o host.c -oo bundles.o --deps hello.exe

        $ cc host.c bundles.o /usr/lib/libmono.a -lc -lrt
.fi
.PP
You may also use \fImkbundle\fP to generate a bundle you can use when
embedding the Mono runtime in a native application.  In that case, use
both the -c and --nomain options.  The resulting host.c file will
not have a main() function.  Call mono_mkbundle_init() before
initializing the JIT in your code so that the bundled assemblies
are available to the embedded runtime.
.SH OLD EMBEDDING OPTIONS
These options can only be used instead of using the 
.B --cross, --runtime 
or
.B --simple 
options.
.TP
.I "-c"
Produce the stub file, do not compile the resulting stub.
.TP
.I "-oo filename"
Specifies the name to be used for the helper object file that contains
the bundle.
.TP
.I "--keeptemp"
By default \fImkbundle\fP will delete the temporary files that it uses to
produce the bundle.  This option keeps the file around.
.TP
.I "--nomain"
With the -c option, generate the host stub without a main() function.
.TP
.I "--static"
By default \fImkbundle\fP dynamically links to mono and glib.  This option
causes it to statically link instead.
.TP
.I "-z"
Compresses the assemblies before embedding. This results in smaller
executable files, but increases startup time and requires zlib to be
installed on the target system.

.SH AOT Options
These options support an mkbundle using AOT compilation with static linking. A native compiler
toolchain is required.
.TP
.I "--aot-runtime PATH"
Provide the path to the mono runtime to use for AOTing assemblies.
.TP
.I "--aot-dedup"
(Experimental) Deduplicate AOT'ed methods based on a unique mangling of method names.
.TP
.I "--aot-mode MODE"
MODE can be either "full" or "llvmonly" at this time.
Currently, mkbundle supports three AOT modes. The default mode (this option unset)
will AOT methods but will fall back on runtime codegen where it is much faster or offers
a more full compatibility profile. The "full" setting will generate the necessary stubs to
not require runtime code generation. The "llvmonly" setting does the same, but forces all codegen
to go through the llvm backend.

.SH WINDOWS
If you are using the old embedding on Windows systems, it it necessary
to have Unix-like toolchain to be installed for \fImkbundle\fP to
work.  You can use cygwin's and install gcc, gcc-mingw and as
packages.
.SH ENVIRONMENT VARIABLES
.TP
.I "AS"
Assembler command. The default is "as".
.TP
.I "CC"
C compiler command. The default is "cc" under Linux and "gcc"
under Windows.
.TP
.I "MONO_BUNDLED_OPTIONS"
Options to be passed to the bundled
Mono runtime, separated by spaces. See the mono(1) manual page or run mono --help.
.SH FILES
This program will load referenced assemblies from the Mono assembly
cache. 
.PP
Targets are loaded from ~/.mono/targets/TARGETNAME/mono
.SH BUGS
The option "--static" is not supported under Windows when using the
old embedding.
Moreover, a full cygwin environment containing at least "gcc" and "as"
is required for the build process. The generated executable does not
depend on cygwin.
