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 Build Process for Users.
13 ========================
15 If you only want to build a snapshot or a fresh CVS checkout of the
16 sources, you should go into the `mono' sibling directory and issue the
19 ./autogen --prefix=/usr/local
22 That will build and install the code in a single pass. The
23 compilation is bundled with the build due to dependencies on the class
24 libraries on the runtime.
26 Build Features for Developers.
27 ==============================
29 These instructions apply to both Linux and Windows. To build this
30 package, you must already have a C# compiler installed. This means
31 that to build on Linux, you need to get a distribution of the MCS
32 binaries; these are called monocharges. They can be found at
33 www.go-mono.com/daily. On Windows, you can just use the
34 Microsoft compiler. You also need GNU make to build the software (on
35 Windows, you will need for example the Cygwin environment setup).
37 You can customize your MCS configuration by using:
39 ./configure [--prefix=PREFIX] [--profile=PROFILE]
41 If you do not run the above, the defaults are /usr/local for the
42 prefix, and `default' for the profile.
44 To build the compiler and class libraries, run:
48 The libraries will be placed in the directory class/lib/ and the mcs
49 compiler executable in mcs/.
51 To install them, run the following:
55 If you get "corlib out of sync" errors, try
59 The difference between the two modes is explained farther down.
64 Occasionally, something in the compiler or runtime changes enough that
65 an existing installation cannot complete a full build from cvs. In this case,
66 go to http://go-mono.com/daily and download a monocharge or monolite tarball.
67 Unpack and copy the .dlls to $prefix/lib and .exes to $prefix/bin/. Then
68 you should be able to complete the build normally (i.e. using make fullbuild).
70 wget http://go-mono.com/daily/monolite-20031028.tar.gz
71 tar -zxvf monolite-20031028.tar.gz
73 cp *.exe /usr/local/bin/.
74 cp *.dll /usr/local/lib/.
79 If you are tracking Mono's development, you may sometimes need to share
80 the compiled libraries with others, you can do:
84 Or a light version, which contains only the essential libraries and
85 results in a much smaller file:
92 If you want to change the configuration options for the build process,
93 place your configuration options in build/config.make
95 A list of variables that control the build are listed in the file
96 build/config-default.make.
99 ======================
101 Don't worry about them too much. If you're wondering which to use:
102 use the default if you can (that's why it's the default!) and use
103 the atomic if you have to.
105 The default profile uses the C# compiler and class libaries as they
106 are built. This lets you build MCS without needing to have already
107 installed it, but can fail if the libraries change significantly.
108 (This is the source of the dreaded "corlib out of sync" warning, most
111 The atomic profile tries to use the system compiler and preexisting
112 MCS libraries. New libaries are built against this constant reference
113 point, so if a newly built library has a binary incompatibility, the
114 rest of your build can proceed.
116 If you want to always use the atomic profile, run this command:
118 ./configure --profile=atomic
120 More About the Build System
121 ===========================
123 More information is found in build/README.*. Here's a quick rundown
126 * Unified build system for Windows and Linux. Windows is still
127 fairly untested, but "should work." Unfortunately I don't
128 have a Windows machine to test on, but Gonzalo can get
129 corlib to build I think and that's about as complicated as
132 * Profile support. 'make PROFILE=profilename' or 'export
133 PROFILE=profilename ; make' will work. Profiles are defined
134 in build/profiles/profilename.make ; right now there isn't
135 too much going on. The 'bootstrap' profile will build the
136 way makefile.gnu did on Linux, by setting MONO_PATH and
137 using mcs/mcs.exe; the default profile will build against
138 the existing system libraries and compile with 'mcs', which
139 should reduce a lot of 'corlib out of sync' warnings.
141 * Important variables are shared among makefiles now; you can
142 edit build/config.make (see build/config-default.make for a
143 template) and give global settings, or just have a much
144 saner time of writing new makefiles.
146 * Response files, stamps, and other build trivia now all land
147 in build/deps/, making the library build directories
150 * Test libraries now live in class/Library/Library_test.dll,
151 not class/Library/Test. 'make test' will build the test DLL,
152 'make run-test' will actually run the nunit tests. Set the
153 variable TEST_HARNESS to run with a program other than
154 nunit-console (for example, nunit-gtk).
156 * Standardized recursive targets: all, clean, install, test,
157 run-test. Read build/README.makefiles for definitions of
160 * (Relatively) sane 'make dist' target; 'make distcheck'
161 support; cute 'make monocharge' and 'make monocharge-lite'
162 targets. They're made possible because 'make install' now
163 supports DESTDIR a la automake, which I'm sure someone cares
