4 The Mono project has developed mono, a CLI runtime. The build process
5 of each of these depends on nothing more than a C compiler and glib2.
7 However, to provide a working runtime environment, these programs must
8 be supplemented by the class libraries, which are written in C#. This
9 package contains the components written in C#: class libraries,
12 *********************************************************************
16 * Unless you are developing the class libraries, you should *
17 * not need to do any build steps in this directory. *
19 * Go to ../mono and read the README file to compile and *
22 * ../mono is where you have your `mono' source download *
24 *********************************************************************
26 If you only want to build a snapshot or a fresh CVS checkout of the
27 sources, you should go into the `mono' sibling directory and issue the
28 make command, like this:
31 ./autogen.sh --prefix=/usr/local
35 The compilation is bundled with the build due to dependencies on the
36 class libraries on the runtime.
38 Build Features for Developers of Mono.
39 ======================================
41 These instructions apply to both Linux and Windows. To build this
42 package, you must already have a C# compiler installed. This means
43 that to build on Linux, you need to get a distribution of the MCS
44 binaries; these are called monocharges. They can be found at
45 www.go-mono.com/daily. On Windows, you can just use the
46 Microsoft compiler. You also need GNU make to build the software (on
47 Windows, you will need for example the Cygwin environment setup).
49 You can customize your MCS configuration by using:
51 ./configure [--prefix=PREFIX] [--profile=PROFILE]
53 If you do not run the above, the defaults are /usr/local for the
54 prefix, and `default' for the profile.
56 To build the compiler and class libraries, run:
60 The libraries will be placed in the directory class/lib/ and the mcs
61 compiler executable in mcs/.
63 To install them, run the following:
67 If you get "corlib out of sync" errors, try
71 A better alternative would be to fire off a 'make' from a sibling or
77 We try to maintain the CVS tree such that it is bootstrapable from the
78 latest released version of mono and mcs. Occasionally, something in the
79 compiler or runtime changes enough that an existing installation cannot
80 complete a bootstrap from cvs. In this case, go to
81 http://go-mono.com/daily and download a monocharge or monolite tarball.
82 Unpack and copy the .dlls to $prefix/lib and .exes to $prefix/bin/.
83 Then you should be able to complete the build normally (i.e. using make
86 wget http://go-mono.com/daily/monolite-20040505.tar.gz
87 tar -zxvf monolite-20040505.tar.gz
89 env prefix=/usr/local sh recharge.sh
94 If you are tracking Mono's development, you may sometimes need to share
95 the compiled libraries with others, you can do:
99 Or a light version, which contains only the essential libraries and
100 results in a much smaller file:
107 If you want to change the configuration options for the build process,
108 place your configuration options in build/config.make
110 A list of variables that control the build are listed in the file
111 build/config-default.make.
113 Build profiles? What?
114 ======================
116 Don't worry about them too much. If you're wondering which to use:
117 use the default if you can (that's why it's the default!) and use
118 the atomic if you have to.
120 The default profile uses the C# compiler and class libaries as they
121 are built. This lets you build MCS without needing to have already
122 installed it, but can fail if the libraries change significantly.
123 (This is the source of the dreaded "corlib out of sync" warning, most
126 The atomic profile tries to use the system compiler and preexisting
127 MCS libraries. New libaries are built against this constant reference
128 point, so if a newly built library has a binary incompatibility, the
129 rest of your build can proceed.
131 If you want to always use the atomic profile, run this command:
133 ./configure --profile=atomic
135 More About the Build System
136 ===========================
138 More information is found in build/README.*. Here's a quick rundown
141 * Unified build system for Windows and Linux. Windows is still
142 fairly untested, but "should work." Unfortunately I don't
143 have a Windows machine to test on, but Gonzalo can get
144 corlib to build I think and that's about as complicated as
147 * Profile support. 'make PROFILE=profilename' or 'export
148 PROFILE=profilename ; make' will work. Profiles are defined
149 in build/profiles/profilename.make ; right now there isn't
150 too much going on. The 'bootstrap' profile will build the
151 way makefile.gnu did on Linux, by setting MONO_PATH and
152 using mcs/mcs.exe; the default profile will build against
153 the existing system libraries and compile with 'mcs', which
154 should reduce a lot of 'corlib out of sync' warnings.
156 * Important variables are shared among makefiles now; you can
157 edit build/config.make (see build/config-default.make for a
158 template) and give global settings, or just have a much
159 saner time of writing new makefiles.
161 * Response files, stamps, and other build trivia now all land
162 in build/deps/, making the library build directories
165 * Test libraries now live in class/Library/Library_test.dll,
166 not class/Library/Test. 'make test' will build the test DLL,
167 'make run-test' will actually run the nunit tests. Set the
168 variable TEST_HARNESS to run with a program other than
169 nunit-console (for example, nunit-gtk).
171 * Standardized recursive targets: all, clean, install, test,
172 run-test. Read build/README.makefiles for definitions of
175 * (Relatively) sane 'make dist' target; 'make distcheck'
176 support; cute 'make monocharge' and 'make monocharge-lite'
177 targets. They're made possible because 'make install' now
178 supports DESTDIR a la automake, which I'm sure someone cares
