This is Mono.
1. Installation
2. Using Mono
3. Directory Roadmap
1. Compilation and Installation
a. Build Requirements
To build Mono, you will need the following components:
* pkg-config
Available from:
* glib 2.0
Available from:
Optional dependencies:
* ICU library
You will need this one to get complete support for the international
features of the .NET Framework.
* Cairo and libgdiplus
If you want to get support for System.Drawing, you will need to get
both Libgdiplus and Cairo.
b. Building the Software
If you obtained this package as an officially released tarball,
this is very simple, use configure and make:
./configure --prefix=/usr/local
make install
Mono supports a JIT engine on x86, SPARC and PowerPC systems.
The various commands that ship with Mono default to the JIT engine
on x86 and SPARC, to turn it on for PPC systems, use the --with-jit=yes
command line option to configure.
MacOS X Users: you will need to download the latest Boehm GC
Alpha release for garbage collection to work properly.
If you obtained this as a snapshot, you will need an existing
Mono installation. To upgrade your installation, unpack both
mono and mcs:
tar xzf mcs-XXXX.tar.gz
tar xzf mono-XXXX.tar.gz
mv mono-XXX mono
mv mcs-XXX mcs
cd mono
./ --prefix=/usr/local
make bootstrap
c. Building the software from CVS
If you are building the software from CVS, make sure that you
have up-to-date mcs and mono sources:
cvs co mono mcs
Then, go into the mono directory, and configure:
cd mono
./ --prefix=/usr/local
Depending on whether you have an existing Mono installation or
not, you can try the following:
i. If you have an existing Mono installation
First verify that you have a working installation:
echo 'class X { static void Main () { System.Console.Write("OK");}}' > x.cs
mcs x.cs
And run:
mono x.exe
If you get the output `OK' and no errors, and you have mono
version 0.31 or later, continue. Otherwise, you can try option
(ii) below.
You are ready to start your CVS upgrade. Compile with
make bootstrap
This will automatically go into the mcs/ tree and build the
binaries there, and copy them into the appropriate
sub-directories of mono/runtime/.
Now, go to step (iii) below.
ii. If you don't have a working Mono installation
If you don't have a working Mono installation, an obvious choice
is to install the latest released packages of 'mono' for your
distribution and go back to step (i).
You can also try a slightly more risky approach that should work
almost all the time.
This works by first getting the latest version of the 'monolite'
distribution, which contains just enough to run the 'mcs'
compiler. You do this by
make get-monolite-latest
This should place a monolite-latest.tar.gz in the parent
directory of the 'mono' source tree. You can then run:
make monolite-bootstrap
This will automatically gunzip and untar the tarball, place the
files appropriately, and then complete the bootstrap.
iii. Testing and Installation
You can run the mono and mcs testsuites with the command:
make -k bootstrap-check
Expect to find several testsuite failures, especially in the
mcs/ tree. As a sanity check, you can compare the failures you
got with
You can now install it:
make install
Failure to follow these steps will result in a broken installation.
iv. Other useful "bootstrap"-like facilities
If you have a CVS snapshot that you keep updating periodically,
and/or do your development in, you may try using a couple of
specialty make targets that may be slightly faster than a
"make bootstrap".
You can try a two-stage bootstrap with:
make faststrap
This assumes that you have already run a "make bootstrap" on the
tree before.
If you want to avoid waiting even for that, you can try the
riskier one-stage build:
make fasterstrap
This should be attempted only if you're sure that the sources of
the mcs compiler itself and the sources of the libraries used by
it have not been changed.
2. Using Mono
Once you have installed the software, you can run a few programs:
* runtime engine
mono program.exe
mint program.exe
* C# compiler
mcs program.cs
* CIL Disassembler
monodis program.exe
See the man pages for mono(1), mint(1), monodis(1) and mcs(2)
for further details.
