This is Parrot, version 3.10.0

Parrot is Copyright (C) 2001-2011, Parrot Foundation.


This code is distributed under the terms of the Artistic License 2.0.
For more details, see the full text of the license in the file LICENSE.

Parrot is a virtual machine designed to efficiently compile and execute
bytecode for dynamic languages.


You need a C compiler, a linker, and a make program of course.

If you will be linking with the ICU library you have to download and install it
before configuring Parrot. Get it from

You also need Perl 5.8.4 or newer, and Storable 2.12 or newer
for running various configure and build scripts.

For most of the platforms that we are supporting initially, Parrot should build
out of the box. docs/parrot.pod lists the core platforms. PLATFORMS provides
reports on the platforms on which Parrot has been built and tested.

I.  Install Git.

The method depends on your distribution. To install you should execute (as root or sudo <cmd>):

On Ubuntu/Debian (apt-based):

    apt-get install git-core

On Red Hat, Fedora (rpm-based):

    yum install git

on Gentoo (portage):

    emerge -av dev-vcs/git

There are 2 Git ports on Windows:


Macintosh OS X:

An Internet search will locate a variety of git installers for Mac OS X,
including this:

II.  Obtaining Parrot from

To get a copy of the Parrot Git repository:

    git clone git://

This will checkout the master branch by default. To create a local branch
that tracks the branch "some_branch":

    git checkout -b --track some_branch origin/some_branch

All the above URLs are read-only. If you are a Parrot core developer, then
use the read-write URL:

    git clone

You can view the list of branches at


For now, unpack your Parrot tarball, (if you're reading this, you've
probably already done that) and type

    perl --optimize

to run the Configure script. The script extracts configuration
from the running perl5 program.  You may need to explicitly tell
which compiler and linker to use.  For example, to compile C files with 'cc',
C++ files with 'CC', and link everything together with 'CC', you would type

    perl --cc=cc --link=CC --ld=CC

See "perl --help" for more options and docs/configuration.pod
for more details.

For systems like HPUX that don't have inet_pton please run

    perl --define=inet_aton

Running will generate a config.h header, a Parrot::Config
module, platform files and many Makefiles.

The file "myconfig" has an overview of configure settings.

Next, run make. ( will tell you which version of make it
recommends for your system.)

Now, the interpreter should build.  If you are building the ICU library
(this is the default on most systems), you need to use GNU make instead
(or something compatible with it).

You can test Parrot by running "make test". You can run the tests in parallel
with "make TEST_JOBS=3 test".

You can run the full test suite with

    make fulltest

Note: PLATFORMS contains notes about whether test failures are expected
on your system.

You can install Parrot with:

    make install

By default, this installs in /usr/local, with the Parrot executable in
/usr/local/bin. If you want to install Parrot into another location use:

    perl --prefix=/home/joe/bird
    make install

But please note that dynamic libs will not be found for non-standard
locations unless you set LD_LIBRARY_PATH or similar.

Look at docs/parrot.pod and docs/intro.pod for where to go from here.  If you
have any problems, see the section "How To Submit A Bug Report" in
docs/submissions.pod.  These documents are in POD format. You can view these
files with the command:

    perldoc -F docs/intro.pod
