PREREQUISITES
-------------

You'll 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 http://www-306.ibm.com/software/globalization/icu/downloads.jsp

You'll also need Perl 5.6.1 or above to run various configure and build
scripts.

For most of the platforms that we are supporting initially,
Parrot should build out of the box.
The list of targeted platforms can be found in PLATFORMS.

The current configure system is primitive, as it's only
a temporary solution. It will be happy with most any answers
you decide to feed it. Garbage In, Garbage Out.

INSTRUCTIONS
------------

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

    perl Configure.pl

to run the Configure script. The Configure.pl script extracts
configuration from the running perl5 program.  Unfortunately, the perl5
configuration is not set up to compile and link c++ programs, so you
may need to explicitly tell Configure.pl 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 Configure.pl --cc=cc --cxx=CC --link=CC --ld=CC

See "perl Configure.pl --help" for more options.

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

    perl Configure.pl --define=inet_aton

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

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

Next, run make:

For UNIX like systems that come with its own make, 'gmake' should be
used.  (On most Linux systems, this is the default make.)

On windows systems, 'nmake' is used

On other systems, just try 'make'

NOTE: do *NOT* use the '-j' option to make. The dependencies in the generated
Makefile work if you do them sequentially, but running with -j will almost
certainly cause a build error. Patches welcome.

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).

NOTE: If you have trouble linking parrot, this *may* be due to a pre-existing
parrot version installed via 'make install'. Until this issue is resolved,
you may have to delete the installed version of parrot before building a new
one. Our apologies.

You can test parrot by running

    make test         (or nmake test or gmake test)

You can run the full test suite with

    make fulltest

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

On some systems you can install parrot:

    make install

This installs a bunch of files in /usr/local. The parrot executable is in
/usr/local/bin.   Please note that this feature is currently experimental.

If you want to install Parrot into a non-standard location use:

    perl Configure.pl --prefix=/Users/foo/parrot-0.4.7
    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 "Reporting Problems" in docs/intro.pod.
These documents are in POD format. You can view these files with:

    perldoc -F docs/intro.pod

NOTES
-----

On some older computers with little RAM, the computed-goto dispatch core
(ops/core_ops_cg.c) may take a while to compile or may fail to compile at all.
You can pass a flag to Configure.pl (--cgoto=0) to disable the computed-goto
core, at a slight cost in runtime speed.

previous versions, please see NEWS.
