Devel::Size - Perl extension for finding the memory usage of Perl variables

SYNOPSIS

use Devel::Size qw(size total_size);

my $size = size("A string");

my @foo = (1, 2, 3, 4, 5);
my $other_size = size(\@foo);

my $foo = {a => [1, 2, 3],
    b => {a => [1, 3, 4]}
       };
my $total_size = total_size($foo);

DESCRIPTION

This module figures out the real size of Perl variables in bytes, as accurately as possible.

Build and Install

To build and install this module, you need:

Perl
a working C or C++ compiler
a make (or namke on Windows) utility

Follow these steps:

On Linux, Cygwin, or Unix:

perl Makefile.PL
make
make test
sudo make install

On most systems, it is necessary to link to libstdc++. On such systems, libstdc++ should be found automatically (by default). If libstdc++ is *not* being found automatically (in which case you'll get link errors),then instead of running 'perl Makefile.PL', you'll need to run:

perl Makefile.pl LIBS="-L/path/to/libstdc++ -lstdc++"

On Windows:

perl Makefile.PL
nmake
nmake test
nmake install
