Common Configuration Options + ------------------------------- + + The following are the configuration options that someone + building Mono might want to use: + + + --with-gc=[boehm, included, sgen, none] + + Selects the 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. + + It is essentially a slightly modified Boehm GC + + 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. + + sgen: + The under-development Generational GC for + Mono, do not use this in production. + + none: + Disables the inclusion of a garbage + collector. + + --with-tls=__thread,pthread + + Controls how Mono should access thread local storage, + pthread forces Mono to use the pthread APIs, while + __thread uses compiler-optimized access to it. + + Although __thread is faster, it requires support from + the compiler, kernel and libc. Old Linux systems do + not support with __thread. + + This value is typically pre-configured and there is no + need to set it, unless you are trying to debug a + problem. + + --with-sigaltstack=yes,no + + Experimental: Use at your own risk, it is known to + cause problems with garbage collection and is hard to + reproduce those bugs. + + 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. + + 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. + + --with-static_mono=yes,no + + This controls whether `mono' should link against a + static library (libmono.a) or a shared library + (libmono.so). + + This defaults to yes, and will improve the performance + of the `mono' program. + + 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. + + --with-xen-opt=yes,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-large-heap=yes,no + + Enable support for GC heaps larger than 3GB. + + This value is set to `no' by default. + + --enable-small-config=yes,no + + Enable some tweaks to reduce memory usage and disk footprint at + the expense of some capabilities. Typically this means that the + 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). + + This value is set to `no' by default. - iv.

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. + + See the http://www.mono-project.com/Mono_LLVM for the + full details and up-to-date information on this feature. + + You will need to have an LLVM built that Mono can link + against + + --enable-big-arrays + + This enables the use arrays whose indexes are larger + than Int32.MaxValue. + + 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). + + In certain scenarios where large arrays are required, + you can pass this flag and Mono will be built to + support 64-bit arrays. + + This is not the default as it breaks the C embedding + ABI that we have exposed through the Mono development + cycle. + + --enable-parallel-mark + + Use this option to enable the garbage collector to use + multiple CPUs to do its work.
