+------------------------
- Expect to find a few testsuite failures. As a sanity check, you
- can compare the failures you got with
+The following are the configuration options that someone
+building Mono might want to use:
- https://wrench.mono-project.com/Wrench/
+* `--with-sgen=yes,no` - Generational GC support: Used to enable or disable the
+compilation of a Mono runtime with the SGen garbage collector.
- You can now install mono with:
+ * On platforms that support it, after building Mono, you will have
+both a mono binary and a mono-sgen binary. Mono uses Boehm, while
+mono-sgen uses the Simple Generational GC.
- make install
+* `--with-gc=[boehm, included, sgen, none]` - Selects the default Boehm garbage
+collector engine to use.
- You can verify your installation by using the mono-test-install
- script, it can diagnose some common problems with Mono's install.
+ * *included*: (*slighty modified Boehm GC*)
+This is the default value, and its
+the most feature complete, it will allow Mono
+to use typed allocations and support the
+debugger.
- Failure to follow these steps may result in a broken installation.
+ * *boehm*:
+This is used to use a system-install Boehm GC,
+it is useful to test new features available in
+Boehm GC, but we do not recommend that people
+use this, as it disables a few features.
- d. Configuration Options
- ------------------------
+ * *none*:
+Disables the inclusion of a garbage collector.
- The following are the configuration options that someone
- building Mono might want to use:
-
- --with-sgen=yes,no
+ * This defaults to `included`.
- Generational GC support: Used to enable or disable the
- compilation of a Mono runtime with the SGen garbage collector.
+* `--with-tls=__thread,pthread`
- On platforms that support it, after building Mono, you
- will have both a mono binary and a mono-sgen binary.
- Mono uses Boehm, while mono-sgen uses the Simple
- Generational GC.
+ * Controls how Mono should access thread local storage,
+pthread forces Mono to use the pthread APIs, while
+__thread uses compiler-optimized access to it.
- --with-gc=[boehm, included, sgen, none]
+ * Although __thread is faster, it requires support from
+the compiler, kernel and libc. Old Linux systems do
+not support with __thread.
- Selects the default Boehm garbage collector engine to
- use, the default is the "included" value.
-
- included:
- This is the default value, and its
- the most feature complete, it will allow Mono
- to use typed allocations and support the
- debugger.
+ * This value is typically pre-configured and there is no
+need to set it, unless you are trying to debug a problem.
- It is essentially a slightly modified Boehm GC
+* `--with-sigaltstack=yes,no`
- boehm:
- This is used to use a system-install Boehm GC,
- it is useful to test new features available in
- Boehm GC, but we do not recommend that people
- use this, as it disables a few features.
+ * **Experimental**: Use at your own risk, it is known to
+cause problems with garbage collection and is hard to
+reproduce those bugs.
- none:
- Disables the inclusion of a garbage
- collector.
+ * This controls whether Mono will install a special
+signal handler to handle stack overflows. If set to
+`yes`, it will turn stack overflows into the
+StackOverflowException. Otherwise when a stack
+overflow happens, your program will receive a
+segmentation fault.
- --with-tls=__thread,pthread
+ * The configure script will try to detect if your
+operating system supports this. Some older Linux
+systems do not support this feature, or you might want
+to override the auto-detection.
- Controls how Mono should access thread local storage,
- pthread forces Mono to use the pthread APIs, while
- __thread uses compiler-optimized access to it.
+* `--with-static_mono=yes,no`
- Although __thread is faster, it requires support from
- the compiler, kernel and libc. Old Linux systems do
- not support with __thread.
+ * This controls whether `mono` should link against a
+static library (libmono.a) or a shared library
+(libmono.so).
- This value is typically pre-configured and there is no
- need to set it, unless you are trying to debug a
- problem.
+ * This defaults to `yes`, and will improve the performance
+of the `mono` program.
- --with-sigaltstack=yes,no
+ * This only affects the `mono' binary, the shared
+library libmono.so will always be produced for
+developers that want to embed the runtime in their
+application.
- Experimental: Use at your own risk, it is known to
- cause problems with garbage collection and is hard to
- reproduce those bugs.
+* `--with-xen-opt=yes,no` - Optimize code for Xen virtualization.
- This controls whether Mono will install a special
- signal handler to handle stack overflows. If set to
- "yes", it will turn stack overflows into the
- StackOverflowException. Otherwise when a stack
- overflow happens, your program will receive a
- segmentation fault.
+ * It makes Mono generate code which might be slightly
+slower on average systems, but the resulting executable will run
+faster under the Xen virtualization system.
- The configure script will try to detect if your
- operating system supports this. Some older Linux
- systems do not support this feature, or you might want
- to override the auto-detection.
+ * This defaults to `yes`.
- --with-static_mono=yes,no
+* `--with-large-heap=yes,no` - Enable support for GC heaps larger than 3GB.
- This controls whether `mono' should link against a
- static library (libmono.a) or a shared library
- (libmono.so).
+ * This defaults to `no`.
- This defaults to yes, and will improve the performance
- of the `mono' program.
+* `--enable-small-config=yes,no` - Enable some tweaks to reduce memory usage
+and disk footprint at the expense of some capabilities.
- This only affects the `mono' binary, the shared
- library libmono.so will always be produced for
- developers that want to embed the runtime in their
- application.
+ * Typically this means that the number of threads that can be created
+is limited (256), that the maximum heap size is also reduced (256 MB)
+and other such limitations that still make mono useful, but more suitable
+to embedded devices (like mobile phones).
- --with-xen-opt=yes,no
+ * This defaults to `no`.
- The default value for this is `yes', and it makes Mono
- generate code which might be slightly slower on
- average systems, but the resulting executable will run
- faster under the Xen virtualization system.
+* `--with-ikvm-native=yes,no` - Controls whether the IKVM JNI interface library is
+built or not.
- --with-large-heap=yes,no
+ * This is used if you are planning on
+using the IKVM Java Virtual machine with Mono.
- Enable support for GC heaps larger than 3GB.
+ * This defaults to `yes`.
- This value is set to `no' by default.
+* `--with-profile4=yes,no` - Whether you want to build the 4.x profile libraries
+and runtime.
- --enable-small-config=yes,no
+ * This defaults to `yes`.
- Enable some tweaks to reduce memory usage and disk footprint at

- number of threads that can be created is limited (256), that the
- maxmimum heap size is also reduced (256 MB) and other such limitations
- that still make mono useful, but more suitable to embedded devices
- (like mobile phones).
+* `--with-moonlight=yes,no`
- This value is set to `no' by default.
+ * Whether you want to generate the Silverlight/Moonlight
+libraries and toolchain in addition to the default
+(1.1 and 2.0 APIs).
- --with-ikvm-native=yes,no
+ * This will produce the `smcs` compiler which will reference
+the Silverlight modified assemblies (mscorlib.dll,
+System.dll, System.Code.dll and System.Xml.Core.dll) and turn
+on the LINQ extensions for the compiler.
- Controls whether the IKVM JNI interface library is
- built or not. This is used if you are planning on
- using the IKVM Java Virtual machine with Mono.
+* `--with-moon-gc=boehm,sgen` - Select the GC to use for Moonlight.
- This defaults to `yes'.
+ * *boehm*:
+Selects the Boehm Garbage Collector, with the same flags
+as the regular Mono build. This is the default.

+ * *sgen*:
+Selects the new SGen Garbage Collector, which provides
+Generational GC support, using the same flags as the

- Whether you want to generate the Silverlight/Moonlight
- libraries and toolchain in addition to the default
- (1.1 and 2.0 APIs).
+ * `sibling' can be used to specify that a libgdiplus
+that resides as a sibling of this directory (mono)
+should be used.
- This will produce the `smcs' compiler which will reference
- the Silverlight modified assemblies (mscorlib.dll,
- System.dll, System.Code.dll and System.Xml.Core.dll) and turn
- on the LINQ extensions for the compiler.
+ * Or you can specify a path to a libgdiplus.
- --with-moon-gc=boehm,sgen
+* `--disable-shared-memory`
- Select the GC to use for Moonlight.
+ * Use this option to disable the use of shared memory in
+Mono (this is equivalent to setting the MONO_DISABLE_SHM
+environment variable, although this removes the feature
+completely).
- boehm:
- Selects the Boehm Garbage Collector, with the same flags
- as the regular Mono build. This is the default.
+ * Disabling the shared memory support will disable certain
+features like cross-process named mutexes.
- sgen:
- Selects the new SGen Garbage Collector, which provides
- Generational GC support, using the same flags as the
- mono-sgen build.
+* `--enable-minimal=LIST`
- This defaults to `boehm'.
+ * Use this feature to specify optional runtime
+components that you might not want to include. This
+is only useful for developers embedding Mono that
+require a subset of Mono functionality.
+ * The list is a comma-separated list of components that
+should be removed, these are:
- --with-libgdiplus=installed,sibling,<path>
+ * `aot`:
+Disables support for the Ahead of Time compilation.
- This is used to configure where should Mono look for

- Use this option to disable the use of shared memory in
- Mono (this is equivalent to setting the MONO_DISABLE_SHM
- environment variable, although this removes the feature
- completely).
+ * `generics`:

+allow Mono to run any 2.0 libraries or
+code that contains generics.
- Disabling the shared memory support will disable certain
- features like cross-process named mutexes.

+Removes the JIT engine from the build, this reduces
+the executable size, and requires that all code
+executed by the virtual machine be compiled with
+Full AOT before execution.
- --enable-minimal=LIST
+ * `large_code`:
+Disables support for large assemblies.
- Use this feature to specify optional runtime
- components that you might not want to include. This

+* `--enable-llvm`
+* `--enable-loadedllvm`
- large_code:
- Disables support for large assemblies.
+ * This enables the use of LLVM as a code generation engine
+for Mono. The LLVM code generator and optimizer will be
+used instead of Mono's built-in code generator for both
+Just in Time and Ahead of Time compilations.
- logging:
- Disables support for debug logging.
+ * See the http://www.mono-project.com/Mono_LLVM for the
+full details and up-to-date information on this feature.
- pinvoke:
- Support for Platform Invocation services,
- disabling this will drop support for any
- libraries using DllImport.
+ * You will need to have an LLVM built that Mono can link
+against.
- portability:
- Removes support for MONO_IOMAP, the environment
- variables for simplifying porting applications that

+values (even on 64-bit systems).
- reflection_emit_save:
- Drop support for saving dynamically created
- assemblies (AssemblyBuilderAccess.Save) in
- System.Reflection.Emit.
+ * In certain scenarios where large arrays are required,
+you can pass this flag and Mono will be built to
+support 64-bit arrays.
- shadow_copy:
- Disables support for AppDomain's shadow copies
- (you can disable this if you do not plan on
- using appdomains).
+ * This is not the default as it breaks the C embedding
+ABI that we have exposed through the Mono development
+cycle.
- simd:
- Disables support for the Mono.SIMD intrinsics
- library.
+* `--enable-parallel-mark`
- ssa:
- Disables compilation for the SSA optimization
- framework, and the various SSA-based
- optimizations.
+ * Use this option to enable the garbage collector to use
+multiple CPUs to do its work. This helps performance
+on multi-CPU machines as the work is divided across CPUS.
- --enable-llvm
- --enable-loadedllvm
+ * This option is not currently the default as we have
+not done much testing with Mono.
- This enables the use of LLVM as a code generation engine
- for Mono. The LLVM code generator and optimizer will be
- used instead of Mono's built-in code generator for both
- Just in Time and Ahead of Time compilations.
+* `--enable-dtrace`
- See the http://www.mono-project.com/Mono_LLVM for the
- full details and up-to-date information on this feature.
+ * On Solaris and MacOS X builds a version of the Mono
+runtime that contains DTrace probes and can
+participate in the system profiling using DTrace.
- You will need to have an LLVM built that Mono can link
- against,
- The --enable-loadedllvm variant will make the llvm backend
- into a runtime-loadable module instead of linking it directly
- into the main mono binary.
+* `--disable-dev-random`
- --enable-big-arrays
+ * Mono uses /dev/random to obtain good random data for
+any source that requires random numbers. If your
+system does not support this, you might want to
+disable it.
- This enables the use arrays whose indexes are larger
- than Int32.MaxValue.
+ * There are a number of runtime options to control this
+also, see the man page.
- By default Mono has the same limitation as .NET on
- Win32 and Win64 and limits array indexes to 32-bit
- values (even on 64-bit systems).
+* `--enable-nacl`
- In certain scenarios where large arrays are required,
- you can pass this flag and Mono will be built to
- support 64-bit arrays.
+ * This configures the Mono compiler to generate code
+suitable to be used by Google's Native Client:
+http://code.google.com/p/nativeclient/
- This is not the default as it breaks the C embedding
- ABI that we have exposed through the Mono development
- cycle.
+ * Currently this is used with Mono's AOT engine as
+Native Client does not support JIT engines yet.
- --enable-parallel-mark
+Using Mono
+==========
- Use this option to enable the garbage collector to use
- multiple CPUs to do its work. This helps performance
- on multi-CPU machines as the work is divided across CPUS.
+Once you have installed the software, you can run a few programs:
- This option is not currently the default as we have
- not done much testing with Mono.
+* `mono program.exe` runtime engine
- --enable-dtrace
+* `mcs program.cs` C# compiler
- On Solaris and MacOS X builds a version of the Mono
- runtime that contains DTrace probes and can
- participate in the system profiling using DTrace.
+* `monodis program.exe` CIL Disassembler
+See the man pages for mono(1), mint(1), monodis(1) and mcs(2)
+for further details.
- --disable-dev-random
-
- Mono uses /dev/random to obtain good random data for
- any source that requires random numbers. If your
- system does not support this, you might want to
- disable it.
-
- There are a number of runtime options to control this
- also, see the man page.
-
- --enable-nacl
-
- This configures the Mono compiler to generate code
- suitable to be used by Google's Native Client:
-
- http://code.google.com/p/nativeclient/
-
- Currently this is used with Mono's AOT engine as
- Native Client does not support JIT engines yet.
