.SH NAME
-mcs \- Mono Compiler Suite.
+mcs, gmcs \- Mono Compiler Suite.
.SH SYNOPSIS
.B mcs
[option] [source-files]
be provided in a response file. Response files are referenced by
prepending the @ symbol to the response file name.
.PP
+The
+.I mcs
+compiler is used to compile against the 1.x profile and implements
+C# 1.0 and 2.0 with the exception of generics and nullable types. The
+.I gmcs
+compiler is used to compile against the 2.x profile and implements
+the complete C# 2.0 specification.
+.PP
The Mono C# compiler accepts the same options than the Microsoft C#
compiler does. Those options can start with a slash or a dash
(/checked is the same as -checked). Additionally to this, the
runtime engine on Windows or the Mono runtime engine on Unix systems.
Executables are not bound to a specific CPU or operating system.
.PP
+The Mono C# compiler by default only references three assemblies:
+mscorlib.dll, System.dll and System.Xml.dll. If you want to
+reference extra libraries you must manually specify them using the
+-pkg: command line option or the -r: command line option.
+Alternatively if you want to get all of the System libraries, you can
+use the -pkg:dotnet command line option.
+.PP
.SH OPTIONS
.TP
.I \-\-about
Displays information about the Mono C# compiler
.TP
+.I \-\-addmodule:MODULE1[,MODULE2]
+Includes the specified modules in the resulting assembly.
+.TP
.I -checked, -checked+
Sets the default compilation mode to `checked'. This makes all
the math operations checked (the default is unchecked).
Sets the default compilation mode to `unchecked'. This makes all
the math operations unchecked (this is the default).
.TP
+.I -codepage:ID
+Specifies the code page used to process the input files from the
+point it is specified on. By default files will be processed in the
+Latin-1 code page. The compiler will also automatically detect
+Unicode files that have an embedded byte mark at the beginning.
+.TP
+Other popular encodings are 28591 (Latin1), 1252 (iso-8859-1) and 65001 (UTF-8).
+.TP
+MCS supports a couple of shorthands: "utf8" can be used to specify utf-8 instead
+of using the cryptic 65001 and "reset" restores the automatic handling of
+code pages. These shorthands are not available on the Microsoft compiler.
+.TP
.I \-define:SYMLIST, -d:SYMLIST
Defines the symbol listed by the semi-colon separeted list SYMLIST
SYMBOL. This can be tested in the source code by the pre-processor,
attribute.
.TP
.I \-debug, \-debug+, \-g
-Generate debugging information.
+Generate debugging information. To obtain stack traces with debugging
+information, you need to invoke the mono runtime with the `--debug'
+flag. This debugging information is stored inside the assembly as a
+resource.
.TP
.I \-debug-
Do not generate debugging information.
.TP
+.I \-delaysign+
+Only embed the strongname public key into the assembly. The actual
+signing must be done in a later stage using the SN tool. This is useful
+to protect the private key during development. Note that delay signing
+can only be done using a strongname key file (not a key container). The
+option is equivalent to including [assembly: AssemblyDelaySign (true)]
+in your source code. Compiler option takes precedence over the
+attributes.
+.TP
+.I \-delaysign-
+Default. Strongname (sign) the assembly using the strong name key file
+(or container). The option is equivalent to including [assembly:
+AssemblyDelaySign (false)] in your source code. Compiler option takes
+precedence over the attributes.
+.TP
+.I \-doc:FILE
+Extracts the C#/XML documentation from the source code and stores in in
+the given FILE.
+.TP
+.I \-\-expect-error X L
+The compiler will expect the code to generate an error
+named `X' in line `L'. This is only used by the test suite.
+.TP
.I \-\-fatal
This is used for debugging the compiler. This makes the error emission
generate an exception that can be caught by a debugger.
.TP
-.I \-\-stacktrace
-Generates a stack trace at the time the error is reported, useful for
-debugging the compiler.
+.I \-keyfile:KEYFILE
+Strongname (sign) the output assembly using the key pair present in
+the specified strong name key file (snk). A full key pair is required
+by default (or when using delaysign-). A file containing only the
+public key can be used with delaysign+. The option is equivalent to
+including [assembly: AssemblyKeyFile ("KEYFILE")] in your source code.
+Compiler option takes precedence over the attributes.
+.TP
+.I \-keycontainer:CONTAINER
+Strongname (sign) the output assembly using the key pair present in
+the specified container. Note that delaysign+ is ignored when using
+key containers. The option is equivalent to including [assembly:
+AssemblyKeyName ("CONTAINER")] in your source code. Compiler option
+takes precedence over the attributes.
+.TP
+.I \-langversion:TEXT
+The option specifies the version of the language to use. The feature
+set is different in each C# version. This switch can be used to force
+the compiler to allow only a subset of the features.
+The possible values are:
+.nf
+
+Default - Instruct compiler to use the latest version. Equivalent
+is to omit the switch.
+
+ISO-1 - Restrict compiler to use only ISO standardized features.
+The usage of features such as generics, static classes, anonymous
+methods will lead to error.
+.Sp
+Notice that this flag only controls the language features available to
+the programmer, it does not control the kind of assemblies produced.
+Programs compiled with mcs will reference the 1.1 APIs, Programs
+compiled with gmcs reference the 2.0 APIs.
.TP
.I -lib:PATHLIST
Each path specified in the comma-separated list will direct the
Directs the compiler to look for libraries in the specified path.
Multiple paths can be provided by using the option multiple times.
.TP
+.I \-main:CLASS
+Tells the compiler which CLASS contains the entry point. Useful when
+you are compiling several classes with a Main method.
+.TP
.I \-nostdlib, -nostdlib+
Use this flag if you want to compile the core library. This makes the
compiler load its internal types from the assembly being compiled.
Makes the compiler ignore warnings specified in the comma-separeted
list WARNLIST>
.TP
+.I -optimize, -optimize+, -optimize-
+Controls whether to perform optimizations on the code. -optimize and
+-optimize+ will turn on optimizations, -optimize- will turn it off.
+The default in mcs is to optimize+.
+.TP
.I -out:FNAME, -o FNAME
Names the output file to be generated.
.TP
.I \-\-parse
Used for benchmarking. The compiler will only parse its input files.
.TP
-.I \-\-probe X L
-Probes for the code to generate an error named `X' in line `L'. This
-is only used by the test suite.
-.TP
-.I /linkresource:RESOURCE
-Links to the given resources
+.I \-pkg:package1[,packageN]
+The compiler will invoke pkg-config --libs on the set of packages
+specified on the command line to obtain libraries and directories to
+compile the code.
+.PP
+This is typically used with third party components, like this:
+.nf
+ $ mcs -pkg:gtk-sharp demo.cs
+.fi
+.TP
+.TP
+.I \-pkg:dotnet
+This will instruct the compiler to reference the System.* libraries
+available on a typical dotnet framework installation, notice that this
+does not include all of the Mono libraies, only the System.* ones. This
+is a convenient shortcut for those porting code.
+.TP
+.I -resource:RESOURCE[,ID]
+Embeds to the given resource file. The optional ID can be used to
+give a different name to the resource. If not specified, the resource
+name will be the file name.
+.TP
+.I -linkresource:RESOURCE[,ID]
+Links to the specified RESOURCE. The optional ID can be used to give
+a name to the linked resource.
+.TP
+.I -r:ASSEMBLY1[,ASSEMBLY2], \-r ASSEMBLY1[,ASSEMBLY2]
+Reference the named assemblies. Use this to use classes from the named
+assembly in your program. The assembly will be loaded from either the
+system directory where all the assemblies live, or from the path
+explicitly given with the -L option.
+.PP
+You can also use a semicolon to separate the assemblies instead of a
+comma.
.TP
.I \-recurse:PATTERN, --recurse PATTERN
Does recursive compilation using the specified pattern. In Unix the
shell will perform globbing, so you migth want to use it like this:
.PP
.nf
- bash$ mcs -recurse:'*.cs'
+ $ mcs -recurse:'*.cs'
.fi
.TP
+.I \-\-stacktrace
+Generates a stack trace at the time the error is reported, useful for
+debugging the compiler.
+.TP
.I \-target:KIND, \-t:KIND
-Used to specify the desired target. The possible values are: exe,
-winexe, library and module.
+Used to specify the desired target. The possible values are: exe
+(plain executable), winexe (Windows.Forms executable), library
+(component libraries) and module (partial library).
.TP
.I \-\-timestamp
Another debugging flag. Used to display the times at various points
.I \-unsafe, -unsafe+
Enables compilation of unsafe code.
.TP
+.I \-v
+Debugging. Turns on verbose yacc parsing.
+.TP
+.I \-v2
+Turns on C# 2.0 language features.
+.TP
+.I \-\-version
+Shows the compiler version.
+.TP
.I \-warnaserror, \-warnaserror+
Treat warnings as errors.
.TP
Sets the warning level. 0 is the lowest warning level, and 4 is the
highest. The default is 2.
.TP
-.I -r:ASSEMBLY, \-r ASSEMBLY
-Reference the named assembly. Use this to use classes from the named
-assembly in your program. The assembly will be loaded from either the
-system directory where all the assemblies live, or from the path
-explicitly given with the -L option.
+.I \-win32res:FILE
+Specifies a Win32 resource file (.res) to be bundled into the
+resulting assembly.
.TP
-.I \-v
-Debugging. Turns on verbose yacc parsing.
+.I \-win32icon:FILE
+Attaches the icon specified in FILE on the output into the resulting
+assembly.
.TP
.I \-\-
Use this to stop option parsing, and allow option-looking parameters
.SH NOTES
During compilation the MCS compiler defines the __MonoCS__ symbol,
this can be used by pre-processor instructions to compile Mono C#
-compiler specific code.
+compiler specific code. Please note that this symbol is only to test
+for the compiler, and is not useful to distinguish compilation or
+deployment platforms.
