=head1 NAME
Configure.pl - Parrot's Configuration Script
=head1 SYNOPSIS
% perl Configure.pl [options]
=head1 DESCRIPTION
This is Parrot's configuration script. It should be run to create the
necessary system-specific files before building Parrot.
=head2 Command-line Options
General Options
=over
=item C<--help>
Prints out a description of the options and exits.
=item C<--version>
Prints out the version number of Configure.pl and exits.
=item C<--verbose>
Tells Configure.pl to output extra information about the configuration
data it is setting.
=item C<--verbose=2>
Tells Configure.pl to output information about i<every> setting added or
changed.
=item C<--verbose-step={N|regex}>
Run C<--verbose=2> for step number C<N> or matching description.
=item C<--nomanicheck>
Tells Configure.pl not to run the MANIFEST check.
=item C<--prefix>
Sets the location where parrot will be installed.
=item C<--ask>
This turns on the user prompts.
=back
Compile Options
You can add and remove option values with C<< :rem{<opt>} >> and
C<< :add{<opt>} >>. For example:
perl Configure.pl --ccflags=":rem{-g} :add{-O2}"
=over
=item C<--debugging=0>
Debugging is turned on by default. Use this to disable it.
=item C<--profile>
Turn on profiled compile (gcc only for now)
=item C<--optimize>
Tell the compiler to do an optimization phase.
=item C<--inline>
Tell Configure that the compiler supports C<inline>.
=item C<--cc=(compiler)>
Specify which compiler to use.
=item C<--ccflags=(flags)>
Use the given compiler flags.
=item C<--ccwarn=(flags)>
Use the given compiler warning flags.
=item C<--cxx=(compiler)>
Specify which C++ compiler to use (for ICU).
=item C<--libs=(libs)>
Use the given libraries.
=item C<--link=(linker)>
Specify which linker to use.
=item C<--linkflags=(flags)>
Use the given linker flags
=item C<--ld=(linker)>
Specify which loader to use for shared libraries.
=item C<--ldflags=(flags)>
Use the given loader flags for shared libraries
=item C<--lex=(lexer)>
Specify which lexer to use.
=item C<--yacc=(parser)>
Specify which parser to use.
=item C<--define=val1[,val2]>
Generate "#define PARROT_DEF_VAL1 1" ... entries in has_header.h.
Currently needed to use inet_aton for systems that lack inet_pton:
--define=inet_aton
=back
Parrot Options
=over
=item C<--intval=(type)>
Use the given type for C<INTVAL>.
=item C<--floatval=(type)>
Use the given type for C<FLOATVAL>.
=item C<--opcode=(type)>
Use the given type for opcodes.
=item C<--ops=(files)>
Use the given ops files.
=item C<--pmc=(files)>
Use the given PMC files.
=item C<--cgoto=0>
Don't build cgoto core. This is recommended when you are short of memory.
=item C<--jitcapable>
Use JIT system.
=item C<--execcapable>
Use JIT to emit a native executable.
=item C<--gc=(type)>
Determine the type of garbage collection. The value for C<type> should
be one of: C<gc>, C<libc>, C<malloc> or C<malloc-trace>. The default is
C<gc>.
=back
ICU Options
=over
=item C<--icu-config=/path/to/icu-config>
Use the specified icu-config script to determine the necessary ICU options.
Use --icu-config=none to disable the autodetect feature. Parrot will
then be build with its own ICU.
B<Note:> If you specify another ICU option than --icu-config, the
autodetection functionality will be disabled.
=item C<--icuplatform=(platform)>
Use the given platform name to pass to ICU's runConfigureICU. (See icu/source/runConfigureICU for the list of available "platform" names, which specify both operating system and compiler.)
=item C<--icuconfigureargs=(arguments)>
Pass the given arguments to ICU's configuration script, instead of the default.
=item C<--icudatadir=(path)>
Use the given directory to locate ICU's data file(s) at runtime
If you have an installed unicode package, you can use these two options instead:
=item C<--icushared=(linkeroption)>
Linker command to link against ICU library version 2.6.
E.g.
--icushared='-L /opt/openoffice/program -licudata -licuuc'
(The libs in openoffice are actually version 2.2 and do not work)
=item C<--icuheaders=(header_dir)>
Location of ICU header files without the /unicode suffix. The header files must match your platform, especially F<platform.h> must be present.
E.g.
--icuheaders='/home/lt/icu/'
You might also need '--nomanicheck'.
=back
Other Options
=over
=item C<--maintainer>
Use this option if you want imcc's parser and lexer files to be
generated. Needs a working parser and lexer.
=item C<--miniparrot>
Build parrot assuming only pure ANSI C is available.
=item C<--expnetwork>
Enable experimental networking. This is an unused option and should
probably be removed.
=back

--verbose-step=N Set verbose for step N only
--verbose-step=regex Set verbose for step matching description
--nomanicheck Don't check the MANIFEST
--prefix Set the installation prefix
--ask Have Configure ask for commonly-changed info
Compile Options:
You can add and remove option values with :rem{<opt>} and :add{<opt>}
e.g. : --ccflags="rem{-g} :add{-O2}"
--debugging=0 Disable debugging, default = 1
--profile Turn on profiled compile (gcc only for now)
--optimize Optimized compile
--inline Compiler supports inline
--cc=(compiler) Use the given compiler

Parrot Options:
--intval=(type) Use the given type for INTVAL
--floatval=(type) Use the given type for FLOATVAL
--opcode=(type) Use the given type for opcodes
--ops=(files) Use the given ops files
--pmc=(files) Use the given PMC files
--cgoto=0 Don't build cgoto core - recommended when short of mem
--jitcapable Use JIT
--execcapable Use JIT to emit a native executable
--gc=(type) Determine the type of garbage collection
type=(gc|libc|malloc|malloc-trace) default is gc
ICU Options:
For using a system ICU, these options can be used:
--icu-config=/path/to/icu-config
Location of the script used for ICU autodetection.
You just need to specify this option if icu-config
is not in you PATH.
--icu-config=none can be used to disable the autodetection feature.
It will also be disabled if you specify any other
of the following ICU options.
If you do not have a full ICU installation:
--without-icu Build parrot without ICU support
--icuheaders=(path) Location of ICU headers without /unicode
--icushared=(flags) Full linker command to create shared libraries
--icudatadir=(path) Directory to locate ICU's data file(s)
Other Options (may not be implemented):
--maintainer Create imcc's parser and lexer files. Needs a working
parser and lexer.
--miniparrot Build parrot assuming only pure ANSI C is available
--expnetwork Enable experimental networking (unused)

Parrot Version $parrot_version Configure 2.0
Copyright (C) 2001-2005 The Perl Foundation. All Rights Reserved.
Hello, I'm Configure. My job is to poke and prod your system to figure out
how to build Parrot. The process is completely automated, unless you passed in
the `--ask' flag on the command line, in which case it'll prompt you for a few
pieces of info.
Since you're running this script, you obviously have Perl 5--I'll be pulling
some defaults from its configuration.
END
#Run the actual steps
Parrot::Configure::RunSteps->runsteps(%args);
print <<"END";
Okay, we're done!
You can now use `make' (or your platform's equivalent to `make') to build your
Parrot. After that, you can use `make test' to run the test suite.
Happy Hacking,
The Parrot Team
